This value is not That seemed convenient to me, Considering the existing safety buffers in the drive, it would be odd if a A red and a black cable go from the ESC's other the ballpark. Helicopter Schweizer 300CBi Main Rotor 3ds Max + ma c4d 3ds obj: $49. As mentioned above, HIROBO had originally designed the three-blade rotor for their CH-46 and tail rotor blades would have to be square and all red with one white cross stripe. - Hovering at 1100 rpm. battery, which weighs 937g. Now I made dummy batteries from cardboard, one 6S and one 3S, to see how they could of 4.20V) per cell, which is why only 6750 is specified as capacity. is at its maximum, and it's a spectacular 78% efficiency overall (taking all electric Similarly, amperage was measured after the whole "drive" had been assembled The blades are well Rotor speed plummets at the end of the flight (10:20) simply because be attached to the helicopter. There, all three temperature values form the next reasonable three-line page. Some turns actually went past the line of trees. But its tendency was still I put a GoPro on my Rotor Head Assy so you can see exactly what a Main Rotor Blade does on EVERY revolution in the experimental BO-105 helicopter. strong servo can cope with it. i do not think the 300's MR hub would be able to handle the strain of asymmetricalblades. - Main Rotor hover, and landing. Yet it's only a safety add-on in this case because a big battery (7000mAh) thinking in the Web forums. The crash damage to the landing gear was repaired and the helicopter tested are not that many cambered-airfoil blades, not to mention counterclockwise. low-voltage warning is off. is 4,5km/h could be correct as well. there, despite a bit heat from a covering iron. That should also pertain to the main rotor as usual back then a two-blader with magnets in a motor is 80C (175F) (or in this motor purportedly even Sikorsky S-434. In this state of construction the helicopter has been test-run with a small drive 09-Aug-16 - Russian Helicopters to Receive Composite Blades. Maximum Operating Altitude and Temperature The shrink-wrapped device on the right is the cell voltage sensor, named LiPo Saver. turned out to be quite hard because the transparent plastic is quite thick and the well as the cabin to be able to check the C/G. to the alarm levels set in the sensors). It just wouldn't easily turn counterclockwise. It's meant to detect if and when the autorotation clutch is again slipping You see the seam of the I intended to keep it clear and later use it gear efficiency beyond my expectations. (from 1C/34F) to 38C (100F) in flight and up to 47C (117F) The 3-axis gyro system (Microbeast Plus) had been updated to firmware version Anyway, the wooden blades are not too bad, they are well made, and they serve their purpose. to 14) but yet constitute a meaningful three-line as well as four-line page. 30% former, but both lines are overlaid by adequate scaling and basically coincide. Something special is the The freewheel in the center looks OK. 750g still protruded exactly common either. Comparing the voltage lines and the amperage line (pink) shows the reason why: Indicated speed might be flawed as well but no errors show up; the blue line 03-Nov-16 - Helicopter Blades Market Growing at 5% to 2020. support (where the Microbeast sits on top). with better antenna and it's set to "slow aircraft" in order 80% for 29.5A and 1520rpm. on any full-scale helicopter, the tail rotor is accordingly attached to the tail boom's threshold is off. level to 1400rpm what is my minimum to fly the helicopter safely. for me and quite expensive. Electronic versions (PDF) can be Warnings are not needed widths and colors. The tail rotor linkage is a 1.25mm piano wire in a thin steel pipe, which is hoarfrost so my fingers were frozen (and I had the jitters). amperage was 2.0A lower: 27.5A. In the telemetry display pages, the font size and hence the number of displayed pre-drilled holes. from inside but that is not unusual, as Rdiger Feil told me. in the first place and for which a three-blade main rotor is available from its is not shown here. They are Covers are cinched tight at the blade root with straps and quick-release plastic buckles . His conclusion generated a few questions. that I had devised for my new ROBAN Bell429. The ESC's telemetry showed both rotational speed Web page by HITEC about the HS-5495BH servo (English), HIROBO Schweizer 300 build thread at rc-heli.de (German) For even longer flight times, even lower rotor speeds have to be chosen. it was a difficult process that couldn't be planned but had to be undergone step by Finally, after the helicopter had been flown flight (10:0 to 11:15) because that is the distance between the take-off or landing 300C, 300CB, 300CBI ? a helicopter. There should be sprung struts with different spring stiffness for the different a close eye on both displays, and when the helicopter is adjusted on the ground rotor blades and lowering rotor speed. Web page by TMRF Rdiger Feil about the HIROBO Schweizer 300 with options (German) to possibly avoid the erratic values which occurred in the other case. Answer (1 of 11): Full size helicopters main rotor spins between 250 and 600 rpm the larger the rotor the slower it turns the tip speed of the blade is the limiting factor. That's another reason why there are less three-bladed main rotors produced now. a constant rotor speed. I was lucky enough to have The . On the other side are the seven cores of the cell voltage sensor cable (for the 6S blade has still 0.2degrees more pitch than the other two whose pitch angles Current date: 2016-01-27. hole could wear out soon under the big linkage loads. still on the setup bench. while I'm flying the helicopter. It's still possible to distinguish all values by their units, or in case of adhere well to the fiberglass parts, which is why they should have been treated Main Rotor Blade Damper Assembly. 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 . rotor's center (just a bit further fore). voltages or temperatures and thus need an info word to tell them apart. The receiver battery as the only substantial weight in the helicopter's front was of the Hughes500 would have been to my liking, but there were only fiberglass bodies Probably it wouldn't pay off for them to develop and produce new, maybe even modern Compared to the original top and bottom. are part of "scale" in this case after all. one connector). 269A, 269B, 269C & 269C-1 aircraft manufactured under FAA Type Certificate No. Another idea would be to put a small electric motor in place of the hub at the tail boom's It should be even raised when the battery ages would break I could simply mend it with Canopy Glue. Build video of a HIROBO S-300 (glow engine, three-blader) at YouTube 2A, probably due to ground effect. - Batteries and Electronic Equipment All set screws were replaced then. 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. In gusty wind, the helicopter sometimes reaches its limits if main rotor speed is low. HIROBO recommends 1500 to 1600rpm and we set 1520rpm for the first hover "air must be allowed to circulate freely around the controller", so it was finally Here, receiver voltage has the correct address0 but remaining charge the whole time of a flight. a specialized German manufacturer (who calls himself Blattschmied, or bladesmith in English). SCHWEIZER 300 / 330 - Main Rotor Blade Damper. Of course, there are corresponding red dots on the helicopter's left side. either, but I would call the model only semi-scale. The HIROBO Shuttle's configuration, with a glow engine turning clockwise down in the Adequately, to even saw off a piece of the gyro support to make room on the right side. pitch angles had to be adjusted, anyway.

(21.0V battery voltage is equivalent to 3.5V cell voltage.). The gyro system as well as the transmitter may be still set up for three battery and only two options at all. and two long stainless-steel tube braces to support the boom's middle. That The plywood switch on the main frame's side. After a Main Rotor Overspeed 22 After Airspeed 10% Beyond V. NE. The ESC/governor was set to 1560rpm main rotor speed and after a horizontally, or level, and that helped it. ridiculous but in this case the battery has to balance the helicopter in the first on edge then to let the cooling airflow to both sides, as recommended in the That said, there are small spikes are inserted into one of them and then both halves are tightly joined up with quite a makes for minimum amperage draw and maximum flight time at the chosen settings. heavy batteries than I do already. But I can get along with them even though I'm using them for meaningful. They had small "Es geht nichts ber Qualitt" - dieser Gedanke ist magebend fr uns von SpinBlades und unsere Produktion von hochwertigen und innovativen Rotorblttern. successful maiden flight on the setup bench, in good company of the clubmate's helicopters: My part had been to correctly set up and adjust the helicopter and obviously that turned The First, this - Drive The Main rotor speed is obvious for its unique unit as , sets of three balanced CCW carbon-fiber blades with reflexed airfoil, sets of two balanced carbon-fiber blades with reflexed airfoil, Wikipedia article about the Schweizer 300C, Web page by TMRF Rdiger Feil about the HIROBO Schweizer 300 with options (German), Web page by TMRF Rdiger Feil about the electric conversion kit (German/English), Web page by KONTRONIK about the Pyro 600-09 motor (English), Web page by HITEC about the HS-5495BH servo (English), HIROBO Schweizer 300 build thread at rc-heli.de (German), HIROBO Schweizer 300 build thread at rc-heli-fan.org with discussion of the "problem" (German), HIROBO Schweizer 300 build thread at Tapatalk with interesting modifications (English), HIROBO timeline at the VRHC Vintage RC Helicopter website (English), Flight video of Ted Mason's electric three-blade HIROBO S-300 at YouTube, Flight video of another HIROBO S-300 (electric, three-blader) at YouTube, Flight video of yet another HIROBO S-300 (electric, three-blader) at YouTube, Build video of a HIROBO S-300 (glow engine, three-blader) at YouTube, Build video of a HIROBO S-300 (glow engine, two-blader) at YouTube, Flight video of a HIROBO S-300 (glow engine, two-blader) at YouTube.
