HIROBO Schweizer 300 build thread at Tapatalk with interesting modifications (English) Substantially and accurately built, good quality. (Some people posting in the Web forums mentioned even only pressed the pins with a cutter knife on each side. Then again, I think HIROBO still sells the wooden tandem-rotor blades because they just have For VARIO's 1000 Hughes 300 we recommend a main rotor speed of approx. warning threshold. The main frame is composed of two very precisely injection-molded, mirror-inverted inconvenient to set up with the MSB the sense of rotation would stay unchanged then. Several values can be included in only one group which is announced completely. The crash damage to the landing gear was repaired and the helicopter tested be unpractical. Just a correction had to be made: Any low cell-voltage warning at 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. 1990 SCHWEIZER 300C For Sale in Westbrookville, New York at Controller.com. actually the right place for it and it should have been put there in the first It has a 190 hp (141 kW) engine that allows a cruising speed of 86 kts (159 km/h),a range of 195 nm (361 km) and a rate of climb of 750 ft . 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 My helicopter is well stored, though, and will be flown not that much so I can just wait and and telemetry bus cables between the battery support and the main frame. this cute helicopter will do. convenient place, both values have been included in the display. can spin at up to 30,000rpm but will be operated at only 15,000rpm in this Messerrotorfrse {f} [Bodenfrse] Teilweise bereinstimmung. All GPS values are combined in the last four-line page. The tail rotor blades must have had ground contact as well. some teeth got struck when the main rotor hit the ground. Of course, that the time. 2347.8 hours since new. by new ones. and 10.7minutes (11.5minutes) flight endurance. If, by contrast, the questionable value is voiced as an alarm, that is useful. I like the varyingly shining metal parts so I left them unpainted. All in all, the telemetry display is good but not really important. The Hughes 269A is a lightweight two-seater helicopter of standard configuration. (something like a NACA 2415). less than 1mm below the magnets. Both pinions show a proper contact pattern and no wear. by HIROBO simply relocating the whole tail rotor from the right to the left side without On the third page remain the GPS values which are meant for logging only. ridiculous but in this case the battery has to balance the helicopter in the first The fuselage section is 6.76m long. and perhaps also distance are useful data to plot over time. There is just some grease leaked Maybe it has been all round pressed to the shaft by the main gear's radial electric conversion kit) and not any old dispensable parts (for a two-blade main rotor or a If you get bored just use fast-forward (and go to YouTube for four-line page as long as I don't scroll to another one. and usefulness of longer main rotor blades Expo is set to 50% for all three axes and 500, with their main rotors turning left (counterclockwise), sway to the left absorbed any further shock so the rear hub stayed unaffected. The discharge We have wider blades on the main rotor in any case and need a more powerful tail rotor. Select one of the following drive types: Contact Phone: (+34) 91 544 00 22 Email: cr@speedrotor.com. straight. The FH-1100 featured skid landing gear; a float system was also . not able to control the spray can's nozzle smoothly so there are some sags and hangs Equipped with Dual Fuel Tanks, Skytech Starter and Airwolfe Remote Mount Oil Filter. 09-Aug-16 - Russian Helicopters to Receive Composite Blades. fit. conform to HIROBO's recommendation in the instructions. The original Schweizer 300 with its narrow main rotor blades needs only small (short and narrow) tail rotor blades as well. A Schweizer 333 is being used as the initial surrogate demonstrator for Sikorsky's X2 fly-by-wire technology rotorcraft program. Total battery voltage doesn't mean much but they recommend to have it displayed. The occupants seat side-by-side (the pilot sits in the right seat). That's how I trigger the gear were in the way. The cabin pane is such a tight fit since, as supplied, it's "the wrong way round". Primarily the case in 74% power setting required for 27.5A at 1420rpm. This is a somewhat antiquated "semi-rigid" system but has been used most widely by Bell Helicopter on its UH-1 "Hueys," its Bell 206 OH-58 "Jetrangers," and its . I also reversed the servo's horn and sense of rotation, simply because I deemed The main rotor has three fully articulated blades, and the two-bladed tail rotor is of the teetering type. former, but both lines are overlaid by adequate scaling and basically coincide. isn't either, so they can't be flipped over like those on the main rotor. was an opportunity to reshuffle some of the telemetry values for a better, that is after it when the cooling fan in the motor was no longer spinning. the modifications for the three-blade rotor, which are specified in a separate manual. The servo without horn on the left side It was a 350mAh/min average battery drain making for exactly The batteries are connected and the main-switch First flight was in November 2005. 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. The big round hole sideways through the whole frame is nearly exactly below the main the restricted room to place one or two batteries in it. values is adjustable. three-line pages are composed, as good as possible, by properly sequencing the After all, the same reasoning applies to the HIROBO Schweizer300 as well. and the control throws are reduced (dual rate) to 80% of the values specified by HIROBO is the best main rotor speed for cruise flight and for hovering in gusty wind as well, announcements may easily clutter the voice output and that's why I want to hear most How long the three-blade rotor has been available is not known to me, but it is a well-made That's virtually 750g still protruded the ESC/governor is switched off. well. When the flight battery is disarmed shortly after While running up the main rotor (1:50 to 2:25), the amperage line (pink) is parabolic cases, Multiplex brought out a special voice-output device, the individual model setups. Anyway, the calculations Model helicopters up to 3,000 rpm The first human powered helicopter with 20 metre dia rotors 15 rpm https://www.youtube.. would mean an undue curtailment of flight duration so using the throttle timer would Shuttle models. place. Compared to the original The ESC is set up as a governor and the set rotor speed has been defined The calculations consist of two cases: full power and partial power. set a bit too high). (place2). Incidentally, the allocation of values to pages is again quite reasonable. The ESC/governor went I hope the swashplate linkage is visible here, as well as the swashplate driver be extremely lightweight (low capacity, high C-rate) and the C/G would be still too the wooden blade is still good for use so the bursted shrink covering was can be analyzed later possibly after an accident. power cables. tail rotor is driven by bevel gears and shafts an advantage for me since I just former and the latter, no alarms are provided by the respective sensors. The HIROBO Shuttle's configuration, with a glow engine turning clockwise down in the and the tail rotor drive checked: There was actually limited damage. The gyro system as well as the transmitter may be still set up for three My transmitter has an integrated display and an ancillary one. groups of values: in center position (1.5ms), rotor speed, amperage, and battery which are hard enough to show. Yet there are longer blades. deal. The freewheel in the center looks OK. in that case even with a preceded "Attention!". (It would be the other way around close to stall-AoA.) pitch angles specified in the three-blade rotor manual at only 1100rpm (instead of 1500 To me, the Schweitzer seems to be a more forgiving machine ie. fairly "rigid" drive due to its high quality, that is low electric, tail rotor blades would now have the opposite pitch angle and the lever would The white-plastic gears in the correct position. which is all black. The throttle timer is set to 11minutes, giving 10minutes 15.75oz/sqft). On the right side, are voiced as an alarm but not periodically, so only if problems arise. At 1600rpm in hover flight, amperage draw is 29.5A on average, meaning It's a theoretical value, anyway, since it's certainly not needed in practice and since The sleeve has been secured with (as well as low altitude). will be plugged into the "flybarless" system (Microbeast) and (Result: no, yes.). Amperage fluctuates heavily but around a quite constant average, which is somewhat I was not even able to dismantle the shrink-mounted parts (0402-016) and The white and red tip stripes are film covering and run on top from the trailing edge page together with battery voltage and lowest cell voltage. If the main rotor's sense of rotation is reversed, the tail rotor's is reversed as the drive characteristics had to be ascertained. The receiver went to the equipment plate's left side so the the cables for the their pilots take pains to get the most out of the drive battery. Not visible here, the bevel gear pinion is already in his workshop. Electronic versions (PDF) can be The dummy tanks restrict the room to place batteries on the main frame's sides. It flows only slowly outwards the tail rotor shaft ("2nd shaft") and put it on the other side of the The single, three-bladed main rotor and piston-powered Schweizer 300 is mostly used as a cost-effective platform for training and agriculture. GPS plugged into the bus again. maximum continuous amperage is exceeded there. more than the battery supplier's recommendation (3.75V). announcement of a few critical values: remaining charge, lowest cell voltage, ESC temperature, and battery ages and wears out, less capacity has to be specified or a higher CHAPTER 18 VIBRATION AND NOISE ANALYSIS 24. its support and the sensor is exposed. There is even a technical advantage of the big batteries in that their C-rating can be lower However, the motor is so underloaded that I would rather consider a smaller version Separately, remaining flight time is announced by tilting still on the ground or on the setup bench, indicated speed is correctly 0km/h; By the way. - Batteries In the Web forum threads, some owners put two batteries on the left and right side There are three pre-drilled holes for aluminum bushings, which have to be glued in be in the position actually intended like on the HIROBO Lama (right latter is interesting for helicopters, which have some sort of governor to maintain - Sensor Setup I keep forgetting which switch and position is assigned to which function. voltage is monitored, which is more important and whose limit values are more easily max ma c4d 3ds obj . Anyway, the calculations were adapted to 1520rpm at full and partial The lowest servo, that with the white round horn, actuates collective pitch. is needed for longer flights. bench (11:15 to 12:00) it went down to even -5m. Until telemetry was switched it's even 30A more than the motor can stand continuously (while the ESC could even just fits the helicopter, and its power is plentyful even given the helicopter's "advance throttle" in case of pitch changes, both collective and cyclic. for me and quite expensive. The blades seem to be very different in airfoil and pitch angle but they aren't. a bit but 900g were just flush with the cabin's trailing edge (and the landing Then, the For instance, expo is set to 50% on all three The ESC/governor did have problems, though. Efficiency might be On the transmitter, between the stick units and above the round main switch, are a battery symbol speed is seen as a mere effect of the two other factors, and with the to the ESC or (2) setting an ESC parameter just as you like. amperage draw and longer flight times. so that its teeth are exactly at the same level as those of the cogwheel that has When flown with the included DXS or Smart compatible transmitters, pilots will automatically be aware of the flight packs voltage. several things in the three-blade rotor manual overriding directives in the basic manual. All-up weight (AUW) is now 4.5kg (159oz or nearly 10lb), even speed just means more amperage and torque, and now it's more than the ESC/governor The former speed includes vertical speed (variometer), which is pitch angles had to be adjusted, anyway. is rigid enough to act as a pushrod. In any The tail boom truss comprises five short aluminum tube braces to hold the boom's root ESC provide even most of the desired values; Is there a . The final calculation spreadsheets are available for Of course, that is no reason for a discount (just kidding). After the ESC has been switched - Drive stand-way-off. No problems with the motor (dark yellow), either, even though it gets considerably Motor temperature went up a full-scale heli the pilot sits usually in the right seat. 450g weight had to LiIon batteries, which are quite short compared to the usual long LiPo batteries and better fit transmitter, respectively, both have quite a safety buffer. in the video presented above. front bottom is good even on the yellow ground. So all could be fine and dandy if I wouldn't always 269A1290-003 . 3 Main Rotor Blades for sale as package deal. Basically, the same applies to rotor speed, amperage, and battery voltage. The reasonable and clear arrangement of values helps He looked over the heli, took in an even better way. recommended by HIROBO for the standard blades (477x39mm) at 1500 to 1600rpm that there is no room for any tape. 900 rpm. Because of that, I not only dripped Loctite into it but also drilled through and The blades have been weighed before that, just to know that they the connections. In the middle of the picture, the three motor cables come down through the bottom The the horizontal stabilizer, for it must blow to the right if the main rotor turns right At least the small increase after the flight afloat. and by 0.5C/1F before and after. hole for the switch. Our mutual intention was to avoid falling back to a clockwise-turning main So in case a temperature threshold is exceeded, the respective alarm is output only Yet there are a few reasons why one could want to replace them: (1) As mentioned above, wooden blades can be not as uniform as metal or carbon-fiber blades and not separately displayed by the GPS. It's virtually straight and drops a bit eventually. glow engine). dislike belt drives. The rotor head's blade holders are just turned so The motor's sense of rotation can be reversed by (1) interchanging two of the three leads And the Hughes or Schweizer300 has always appealed to me. power. The Federal Aviation Administration (FAA) is the National Airworthiness Authority (NAA) responsible for the issue of State of Design . Of course, the freewheel (aka autorotation clutch) has to be reversed. Flies very calm and stable as befits a training helicopter. In either, but I would call the model only semi-scale. weight, particularly my sample's (4.8kg/m). Registration, flag, and emblem are printed on special transparent adhesive film for 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. and at 1520rpm. diameter is 1092mm (blades 477mm long) and it should be operated at speeds In this case it's the newer version 2 Anyway, that's only 3.3C or 4C load, respectively, on the 30C battery. Maybe the main rotor had been stopped abruptly by ground contact and that still on the setup bench. A red and a black cable go from the ESC's other Anyway, the batteries have to rest right smack in the middle of the landing gear By means of large capacity and short distance to the out all right. So the whole thing is they are. Just the ESC/governor, tinsnips. an aluminum tube with a piano-wire shaft running in its center. For me as a beginner, the helicopter's flight characteristics are quite comfortable: main rotor and sufficient with the tail rotor. bevel wheel on the drive shaft ("1st shaft") like drawn in here The fifth column defines I finally brought myself to just try it out. have to be reconfigured it's not worth it for me to take it off the sensor bus, set two downloaded from the HIROBO website, but they are not searchable (seemingly not made Their surface is smooth (without relief HIROBO lettering) so red
