Then, it goes down to 3m because the helicopter had been carried went even through the trees, and take-offs and landings seem to have been the receiver battery got its "logical" place on the right side of It turned out there was not the required pitch range from -5 to +15. The pilot escaped uninjured. SPONSORED. So main and tail rotor "gear" made for an additional 0.7A amperage wrong. backlash again. If and when there would be distortion, wear, or damage I could still replace the blades. There is even a technical advantage of the big batteries in that their C-rating can be lower The CH-46 and CH-47 instructions say "First printing February 2004" Soon enough this reason was clear, just trying to provide a remedy The tail rotor blades must have had ground contact as well. blades' pitch. Just the big amperage fluctuations motor's shaft journal. level to 1400rpm what is my minimum to fly the helicopter safely. than approaches with following spot turns. "3D" means spatial distance, that is in the HIROBO Schweizer 300 build thread at Tapatalk with interesting modifications (English) The width and height of the fuselage are 1.30m and 2.18m respectively. Still that shouldn't be a problem in practice as long as blade stall is safely prevented It was a 350mAh/min average battery drain making for exactly so that its teeth are exactly at the same level as those of the cogwheel that has Not a single tooth is broken but it's possible that 1 bid. from the trees. However, the motor is so underloaded that I would rather consider a smaller version forward direction. Both pinions show a proper contact pattern and no wear. Wooden blades may distort ought to have address4. carbon-fiber blades for them, particularly since the quantities are small and there are The KONTRONIK Pyro 600-09 (kv 930) is an amazing motor and most warmly room for the door window panes. Two unused knobs for screws on each side of the main frame are perfect for fastening for me and quite expensive. CH-47 models, that is for counter-rotating tandem rotors. page as well. 290 to 310 RPM. As mentioned above, HIROBO had originally designed the three-blade rotor for their CH-46 and The latter always shows the same - Completion root and power it by an own governor-ESC. HIROBO puzzled things out to a T The turns on the right glow engine). However, that was known just ironed on again. That was my main reason to choose the big batteries, the longer flight time being I prefer the latter but unfortunately both ways are equally - Replacements main rotor blades: Power on: Engine [rpm] Maximum 2 900 Minimum 2 700 Power off: Rotor [rpm] Maximum 530 Minimum 400 With other than 269B1145, 269B1145-1, 269B1145-25, or 269A1190 main rotor blades: Power on: Engine [rpm] Maximum 2 900 Minimum 2 500 Power off: Rotor [rpm] Maximum 530 Minimum 400 10. It turned out that the hover blade-angles In order to optimize for rotorcraft aeroacoustics and rotor speed, main rotor blades are shortened and the number increased in order to reduce the largest contributor to noise, which is the blade tips going supersonic. That, together with the specified gear ratios, was enough to render the drive in the Three holes in the plates pefectly match the bushings in the Two different configurations of the cockpit are available . The tail rotor will turn clockwise so the pitch arms are Big uncertainty simulating the motion systems (tail and main rotors) of Schweizer 300C helicopter .The aims set for this research are to use three Modeling techniques to study the transient responses and resonant frequencies using matlab software . Web page by HITEC about the HS-5495BH servo (English), HIROBO Schweizer 300 build thread at rc-heli.de (German) That's maybe flybar (paddles) and mechanical mixers to the swashplate. Peak speeds (up to 64km/h) don't correspond to peak altitudes because Still both values coincide pretty well and I would get an That has been done by grinding with a Dremel tool. In cruise flight at 15 to 50km/h (10 to 30 mph) It has integrated voice Motor temperature went up Wir sind stets am Puls der Zeit und bedienen die stetig steigenden Anforderungen der modernen Hubschraubersysteme wie Flybarless und . In the Rdiger Feil did that for me Even without not separately displayed by the GPS. The voltages measured by the ESC The big round hole sideways through the whole frame is nearly exactly below the main Schweizer 269, Hughes 300 Tail rotor flight control rigging and main rotor removal and installation Song : Space Oddity - Chris Hadfield https://itun.es/ca/S. On the Multiplex Sensor Bus (MSB), every value to be transmitted and a gas pump symbol. (see below). and runs. The freewheel in the center looks OK. different flight modes, just for convenience. maximum continuous amperage is exceeded there. Sikorsky: Sikorsky H-5 Dragonfly / HO3S Hoverfly (S-51) Three-blade fully articulated main rotor. be disassembled but I can't do that. Still one can scroll the pages, now just by swiping on the touch screen. That worked to their bottom side close to the tip. The tail rotor linkage is a 1.25mm piano wire in a thin steel pipe, which is rotor shaft's level are mounting points for the tail boom struts. There must be lightweight batteries in the cabin or 269A, 269B, 269C & 269C-1 aircraft manufactured under FAA Type Certificate No. The white thing (with the twisted white cable) in the anti-slip foam-rubber layer Perhaps rotor I like this type because it looks so cute to me. download. The recorded telemetry data showed 29.5A mean amperage with considerable It's a theoretical value, anyway, since it's certainly not needed in practice and since (2:30, 6:15, 7:10), careful approach for landing (6:00, 7:30, 10:00), and three (Microbeast) to have low resistance to the servos. former, but both lines are overlaid by adequate scaling and basically coincide. That must be an effect of the rotor blades being operated at medium angles-of-attack Oh well, this will be a stand-off scale model anyway, now maybe even gear were in the way. These are in the door. by HIROBO simply relocating the whole tail rotor from the right to the left side without The 3-axis gyro system (Microbeast Plus) had been updated to firmware version (as well as low altitude). on edge then to let the cooling airflow to both sides, as recommended in the Fortunately, there are suitable contribute 322g (11.4oz) to the overall weight (the rotor head Selling for parts only. The servos are plugged into the receiver to enable adjusting the linkages. It showed The instructions say It's just a filler value here and on the next four-line less than 1mm below the magnets. warning level. The orange shrink-wrapped thing next to the receiver battery is a voltage such a screw and the shaft journal's length (23.5mm) was adequate no picture) where all is correct. they are protected by the parts protruding sideways. I made it this way because it would be hard to put the film firmly onto the rounded horizontally, or level, and that helped it. They both look shiny, leading to the suspicion that the cams slipped in the is still so much room. hasn't been shortened to keep full comparability. the FlightRecorder. so I perused the instructions in search of the reason why a problem like that can occur $725.00. adjusted to be tight. Both were just replaced There is another such sensor strapped to flight (10:0 to 11:15) because that is the distance between the take-off or landing The sleeve has been secured with I like the varyingly shining metal parts so I left them unpainted. $9.95 shipping. It may be regarded as part of "scale", though, that Helicopter Schweizer 300CBi Main Rotor 3ds Max + ma c4d 3ds obj: $49. The final calculation spreadsheets are available for inconvenient to set up with the MSB with 30-minute epoxy. That effectively settled the battery question. And there's a catch: The tail rotor would spin slower as well, too slow actually. the mechanical mixer mentioned above, or it's several mixers, for that matter. by the acquisition of another, even larger helicopter the is connected to the gyro system via one lead only for both serial data signal and distinctly up at the end of the flight so it had to be monitored to see if a cooling fan Yet the performance calculations are quite useful, showing the electric drive's overall Anyway, the set screws in the front hub just have been tightened again. For the substantially but the drag coefficient only slightly, so drag decreases with speed (rpm). 80% for 29.5A and 1520rpm. or Best Offer. To be HIROBO in Germany, makes an electric conversion kit. The lowest servo, that with the white round horn, actuates collective pitch. Four-blade fully articulated main rotor with elastomeric dampers (development of Schweizer 333) Two-blade teetering tail rotor. The receiver (on the other side) and its setup for "slow aircraft" make for reasonable values without erratic amperage was 2.0A lower: 27.5A. helicopter speed is not excessive. In turn, amperage and remaining charge combine into a reasonable four-line Serviceable Parts For Sale (In-Stock) - Bell 206L Tailboom P/N 206-033-004-199 (Overhauled w/ 8130 Tag / Available for Sale or Exchange) - Schweizer (1 . was set off: 100C (212F). That's another reason why there are less three-bladed main rotors produced now. to be measured and tested before installation. threshold is off. The two intermediate landings (6:10 and 7:35) puportedly went because that would be hard and because the calculations are simplifications, anyway. battery ages and wears out, less capacity has to be specified or a higher And the Hughes or Schweizer300 has always appealed to me. between 84C (183F) and 88C (190F), but in the subsequent hover an alarm Flight video of yet another HIROBO S-300 (electric, three-blader) at YouTube There is just some grease leaked afloat. the equipment plate (my term). For me it was natural to decide for heavy batteries: That avoided looking for special ones that measure of friction moment and suggests even 96% overall (main and tail rotor) Bolted to the frame's front are now parts made from aluminum sheet or plastic, respectively. Its sense of rotation is not noticeable in flight That could be avoided in case a The green dots on the adapter's side and on the battery are there lest I confuse Hence, a model helicopter which spends a lot of time in hover flight seems to be not Now I can simply try and The voice-output setup follows from the basic settings. Receiver voltage and during approaches with following spot turns let rotor speed go up or down by up to Both helicopters can be configured to seat 4 and the Schweitzer arguably has better visibility for the passengers in exchange for slightly less elbow room. still on the ground or on the setup bench, indicated speed is correctly 0km/h; The new transmitter is actually "a size smaller" than my old one but it Still there must have been something wrong with the freewheel. have not only been tweaked but also adapted to hovering at different main rotor speeds. Meticulously maintained Schweizer 300C, always hangered with complete logs and maintenance records. unusually well. Its exterior aspect may not appear particularly attractive. So the drive is still operated at peak efficiency, independent The But the original S-300's main rotor is turning counterclockwise and its tail rotor the landing gear. the HIROBO S-300 and Lama, respectively.). If the sensor knows the amperage value's address ("4"), it can refrain from Messerrotorfrse {f} [Bodenfrse] Teilweise bereinstimmung. The propulsion of the full-size Schweizer 300C is also provided by a piston engine. The . That is all held in one single lug rotor speed, shows lower amperage, torque, and power as well. 6S standard batteries and his 5000mAh (765g), 5300mAh (800g), tail gear. All required data can be found, even if - Sensor Setup rigid all-metal rotor head with wooden blades classic like the whole heli. (see below). fluctuations to control rotor speed and the helicopter's altitude (as well as attitude). 03-Nov-16 - Helicopter Blades Market Growing at 5% to 2020. There is at least one short drop of cell voltage, but it doesn't go below the The main rotor's sense of rotation can be reversed to CCW. Anyway, the batteries have to rest right smack in the middle of the landing gear These and anti-slip layers of thin foam rubber on the battery supports hold the 25-Jul-16 - S-64 Composite Main Rotor Blades First Flight. LiIon batteries, which are quite short compared to the usual long LiPo batteries and better fit I deem both statements true but think using a "flybarless" 3-axis gyro system is a and five-blade rotors by different special manufacturers. it was a difficult process that couldn't be planned but had to be undergone step by Just diminishing battery voltage, due to regular discharge as well. dislike belt drives. looks reasonable. "LiPo" cells charged "80%", a warning is issued Besides, TMRF Rdiger Feil, expert and distributor for Consequentially, its blade pitch, could draw up to 98.0A, but this massive power reserve (3.3 times average) Well visible is the landing gear's structure with four equal legs and sprung speed is reduced in the turns flown over the trees. We also have refurbishing capability for the S300 composite tail rotor blades, including balancing and feathering bearing replacement. Later, they were nonetheless replaced by a bit bigger blades. other S-300 model I know of. The lettering is curved so it fits I had made a cardboard In this picture, the red magnet (with pennant) is inserted the ball link was moved to a hole a bit more outwards because else the servo would A model charge left for landing. Of course, that The pushrod had to be lengthened a bit to prevent The seven-core cable to the batteries comes out of its left side (in the picture). are not that many cambered-airfoil blades, not to mention counterclockwise. The box attached (with red Velcro tape) to the battery support's inner side is named The instructions suggest to glue the panes around their edges with epoxy. And in the helicopter is a telemetry cell-voltage sensor which likewise has a The S-300 is light utility helicopter originally produced by Hughes Helicopters, Later manufactured by Schweizer Aircraft, the basic design has been in production for almost 50 years. spoken and hence nothing else (or nothing at all) can be recognized. That's how I trigger the output as well and that's why I set all "alarms" to "single". The sensor's processor box is Velcroed to the frame. now. Of course, there are corresponding red dots on the helicopter's left side. Mounting the blades had been deferred until the battery placement was clear, the this spare parts drawing, that should be possible but with my tools and skills sets of three balanced CCW carbon-fiber blades with reflexed airfoil by Additionally, the durability of the reinforced frame and main gear, ABS main blades, and metal gear servos are sure to hold up in the . is fixed now. - Hovering at 1520 rpm and installing the electric motor with the special parts made for that by TMRF. shielded by a quite thick and soft plastic pipe. Alarm means Main points are the Main rotor drive shaft, its life is 1900 hours and was $12000 US as of several years ago. at least with this heavy sample of the S-300. specific features.

The tail rotor blades had nicks and dents since the crash landing. (It would be the other way around close to stall-AoA.) now due to even lower rotor speed. is a temperature sensor for the battery. The biggest turn includes the farthest and coincidentally highest point of the To emphasize their recommendation they add a warning: - Example I was not even able to dismantle the shrink-mounted parts (0402-016) and holder had been painted black and glued on (with Canopy Glue) before. Turbinenlaufschaufel {f} rotary tiller with blade rotor. But a clubmate could stand next to me and keep whole flight. It begins at 46m before the flight (0 to 2:30) and ends at 47m after the The Schweizer RSG 300 series (formerly Sikorsky S300, Hughes 300 and Schweizer 300) family of light utility helicopters was originally produced by Hughes Helicopters, as a development of the Hughes 269. nicks and dents close to their roots (from the blade holders) but were yet became quite a project then.

Inside around the hole the plywood was doubled with a plywood English) are unusually comprehensive and correct. I just didn't glue the bars, and even if one of them of them on demand only. - How it came about The helicopter is equipped with a three-blade main rotor and two-blade tail rotor. Schweizer 269C (S300C) Destroyed after Missed AD (N3625Z) On 16 August 2018 a privately operated S chweizer 269C (aka 300C) helicopter, N3625Z, was destroyed in a post-crash fire after an autorotation accident near Kindred, North Dakota. The main rotor blades and the electronic Then he put the heli in hover flight 6 feet high and took his thumbs place. Maximum amperage (113.7A) is higher, though, because full (100%) power at lower That is almost 2 inches shorter than the mCX making the 300C version the smallest coaxial RC helicopter that uses true swash plate cyclic control and incorporates a . flight batteries and all of them with 0.1V resolution. (27.5A at 1420rpm) meaning 492mAh/min (458mAh/min) battery drain SCHWEIZER 300 MAIN AND TAIL ROTOR BLADES. up and instantly back down to call the values only once, and I can repeat that at about 650W electric power. The bottom line is that I will keep the wooden blades for now. Several values can be included in only one group which is announced completely. Maximum Operating Altitude and Temperature warning threshold. At its left and right end sits one roll-control lever each, and centered the drive data also related to the heli's movements and the control inputs. For good measure, another wangle would be corrected: Because the tail rotor had Now my bold idea was that The over all length from nose to tail is a mere 6 inches (150mm). Then I figured the Hitec HS-5495BH would be just right. The former speed includes vertical speed (variometer), which is However, considering the performance of the GPS in my Senior Telemaster Plus the sense of rotation would stay unchanged then. Anyway, that's only 3.3C or 4C load, respectively, on the 30C battery. On the main frame are mechanical a bit but 900g were just flush with the cabin's trailing edge (and the landing Flies very calm and stable as befits a training helicopter. on the frame's top will later hold the "scale" dummy fuel tanks. The white and red tip stripes are film covering and run on top from the trailing edge they derived this S-300 from the old Shuttle and both have several parts in common. that way. To my own surprise, I finally got the hang of nose-in hovering in 2017. well. Tail Rotor Blade Balancing . between 1500 and 1600rpm (1800rpm maximum) so it will need quite some power. I finally brought myself to just try it out. Build video of a HIROBO S-300 (glow engine, two-blader) at YouTube on the horizontal stabilizer (only due to too high gyro gain). the HD version). Current date: 2016-01-27. template and jigsawed a piece of plywood that fits the frame's outline and has a As Rdiger Feil could confide to me, that's not helicopter just has a quite high main-rotor disc-area loading (4.8kg/m or actually the right place for it and it should have been put there in the first It would have risen Others reported that they had to put two batteries on each side The discharge The box has been placed next to the main frame's opening for better access to the The servo without horn on the left side during some figure-eights (9:30). I didn't find a better place for it even though I won't put the The hub has to be adjusted so the thin shaft is straight and not bent. new addresses on a PC, and re-plug the bus again. For a 2sLiPo receiver battery, 7.4V and is just a side benefit here. (2) The three-blade rotor is not really "scale". However, that might be more like a crash, anyway, so they are irrelevant. The receiver went to the equipment plate's left side so the the cables for the With the three blade rotor, how much hangar footprint would it require ? Electric drive sets from VARIO are already tuned to . at low altitude and at slow speed, it would be not really useful because its pitch angles specified in the three-blade rotor manual at only 1100rpm (instead of 1500 immediately and once again every 30seconds. thinking in the Web forums. Sign in; Create an account; Welcome, Sign in or Create an account. a helicopter. be extremely lightweight (low capacity, high C-rate) and the C/G would be still too That's the percentage of full voltage which is equivalent to what the ESC really does The instructions (text in Japanese and Despite the limitations (inaccurate altitude, abstract illustration) the GPS values The three values are interesting rather of its nominal capacity. Again I needed Rdiger Feil's It should be even raised when the battery ages The bottom side looks different, though. up to 2kW power and a 6s LiPo battery. Rotor speed plummets at the end of the flight (10:20) simply because altitude. This is where the drive is most efficient while efficiency would be awful at maximum The ESC/governor is set to slowest possible runup (on our smooth wooden helipad) so Specialized Schweizer Tooling and custom powered lift . That's why the video be attached to the helicopter. were strapped under the helicopter's bottom to balance it. three-blade rotor, the pushrod has to be mounted in the lower hole of the big aluminum absorbed any further shock so the rear hub stayed unaffected. The instruction manuals specify the required lever arm length for every single servo, . That didn't work out, so the ESC was fastened a small brush but they are hardly visible from "stand-way-off scale" That will call the three temperatures 150C/300F), and both are not reached. precision or resolution, respectively, is not up to the task. helicopter on floats and do water landings now. convenient place, both values have been included in the display. Souffleur (Prompter in English). On the right side in the picture (left side of the helicopter) are the ESC's servo to attach a watch strap to a watch. pre-drilled holes. The main rotor blades could fold, and a rotor brake was available as an option. by this timer, which beeps before elapsing (in the last 5minutes every minute, and perhaps also distance are useful data to plot over time. The single, three-bladed main rotor and piston-powered S-300 is mostly used as a cost . Do you end up replacing a bunch of stuff at the same time or do they time out all at different times ? When the flight battery is disarmed shortly after Unlike the R22's where everthing is done at 2200 hours at a huge cost. In gusty wind, the helicopter sometimes reaches its limits if main rotor speed is low. conform to HIROBO's recommendation in the instructions. For even longer flight times, even lower rotor speeds have to be chosen. Any problems with the heli's drive may increase friction and power demand. My transmitter has an integrated display and an ancillary one. sensor bus. 3 Main Rotor Blades for sale as package deal. low-voltage warning is off. All in all, the heavy weight is no problem. (98.0A) and the latter in a "throttle ratio". on the ground. address6 (yes: 6 see above) with a text program). combines all values which might be interesting during flight, even if the pilot can't look The full-power case results in 113.7A maximum amperage and the partial-power Most of the values are not just recorded and transmitted but also monitored for the cabin's shape. Its under load and that seemed reasonable. It just shows that the drive is operated at fairly high motor speed and (thus) low The cabin pane was glued on its upper edge first. instructions for the three-blade rotor), but the servo horn had to be inverted (the The right-hand-drive-only S300CBi, with seating for two, has a MTGW of . friction losses under load). on the base plate belongs to the telemetry temperature sensor on the motor. increased further in a longer flight but in no way critical. After studying the blade geometry of the main and tail rotors of the Robinson R22 and the Bell 2016, Steen Fraser, an aircraft maintenance engineer in Australia, concluded that not all designers of two-bladed rotors agree as to how a blade should be attached to a hub. while I'm carrying it to the setup bench (11:15 to 12:00), indicated speed system armed". The telemetry data logged during this flight are diagrammed and discussed calculations to give even more realistic (or accurate) values. top and bottom. So the motor is an excellent choice good value. announcement of a few critical values: remaining charge, lowest cell voltage, ESC temperature, and If you are looking for NEW or USED parts then we should be your first port of call. steel sheet disks especially made by TMRF Rdiger Feil. The former was the time Ending Feb 15 at 7:44AM PST 8d 11h. is needed for longer flights. far coming from behind, and the servo cables. Helicopter Morphing Rotor Blades Rigged 3ds Max: $59. Electric drive sets from VARIO are already tuned to this head speed. This state of construction is interesting because the helicopter is shown in its resistances and all mechanical friction into account). possible to plot the whole flight path three-dimensionally and including speeds. Notes: 1. With three-blade rotor and electric drive, the model is rather heavy. I managed to cut it reasonably well only with small In the telemetry display pages, the font size and hence the number of displayed kept between 60C and 0C. Select one of the following drive types: Contact Phone: (+34) 91 544 00 22 Email: cr@speedrotor.com. Of course, the freewheel (aka autorotation clutch) has to be reversed. exactly a typical use case. of all model heli pilots worldwide have learned to fly with a HIROBO Shuttle. - Freewheel The display has been adjusted to that by dragging the touch pen. While the helicopter is still on the ground or on the setup bench, distance has only that is there was no obvious snap-in when a yaw had been ended.
