The latter seemed to be the case here. inner lips into the holes with a small screwdriver. 03-Nov-16 - Helicopter Blades Market Growing at 5% to 2020. After the first flights, the cell-voltage sensor has been relocated from the tail rotor blades would have to be square and all red with one white cross stripe. Almost all values are voiced if and when they exceed or fall below some threshold, The wooden blades are 477mm long from the center of the blade-holder screw to the blade There are three pre-drilled holes for aluminum bushings, which have to be glued in the connections. altitude went up to -1m, but while the helicopter was carried to the setup cooling fan. GPS plugged into the bus again. After the 2020 flying season I purchased a new transmitter. The GPS 3D location data are logged by the FlightRecorder in any case. As mentioned above, HIROBO had originally designed the three-blade rotor for their CH-46 and measure of friction moment and suggests even 96% overall (main and tail rotor) Then again, the splitting detriment is more than offset by the better capacity-to-weight ratio Since voltage ("throttle") is held constant and amperage is inversely proportional The two aluminum stubs on the frame's lower rear side and the molded stubs at the tail The instructions should, or better must be carefully perused and collated, and there are I wanted to reverse the main rotor's sense of rotation performance, idle (no-load) amperage (current, I0), had to be measured. problem since in flight the helicopter is tilted to the left, anyway, and the tail flybar (paddles) and mechanical mixers to the swashplate. side up into the AntiFlash device, making a U-turn. tip, so 577mm would be ideal. heavy batteries than I do already. In this case the whole helicopter sways to the right, by the way, and in They are useless, though, which is why I replaced all of them by a short beep to shorten That's why I don't feel compelled to replace them by carbon-fiber blades, the more so as there a problem. they were used for the test flight after the freewheel replacement but far fore. adjusted to be tight. should be voiced. That's how it should be (in most on it (between both aluminum levers) sits one pitch-control lever. Make: Schweizer. The elastic shaft to the alarm levels set in the sensors). Soon enough this reason was clear, just trying to provide a remedy has 12 channels (instead of 9), is new, and is more modern. Indicated speed might be flawed as well but no errors show up; the blue line The ESC/governor went The "bell" in the frame's center is actually the cooling fan shroud for equipped with modern telemetry as well. But not only a switch and will thus go unnoticed. a small brush but they are hardly visible from "stand-way-off scale" not only but especially in case an alarm is just signalized by sounding a tail rotor is driven by bevel gears and shafts an advantage for me since I just are shown on transmitter displays and announced by a voice-output device. Now the warning level in the ESC had to be set up differently and the ESC had to be together with the two bull gears so in case of autorotation the tail rotor will The That's why I preferred it to anti-flash XT90 connectors, which would have been The 6S had to hang under the bottom and would be prone it needs even 40seconds to 1600rpm. for their notable drawbacks. Technical description*. the equipment plate (my term). just two extra sensors are used to monitor drive battery Of course, general information about this model is given as well. when wooden blades were still commonplace and three-axis gyros were just emerging. While flying a helicopter, such values should be hardly of any interest. are voiced as an alarm but not periodically, so only if problems arise. require only 1100rpm rotor speed with longer and wider blades (580x43mm). flight batteries and all of them with 0.1V resolution. Info word, value, and unit it takes some time to voice all that. Yet it's only a safety add-on in this case because a big battery (7000mAh) My transmitter has an integrated display and an ancillary one. so little amperage that temperature even slightly drops (below 52C/126F). Taking the end-points, mean Indeed this drive is operated where its efficiency curve eta (light blue) Only then it dawned on me that the battery's The tail boom truss comprises five short aluminum tube braces to hold the boom's root I found a natural place for really heavy batteries on - Sensor Setup After all, wooden blades can be not as uniform as metal or fiberglass blades and The rotor system (hub and blades) is very similar to that found on the early versions of the Hughes 269 / Schweizer 300 series helicopters. - Voice Output ball links have to be taken off the horn in addition. and cell voltage matter so much to me that they are always voiced, regardless of switch position, although just every 2minutes (Timer1). To be alarm on the transmitter in case the freewheel would slip. Both were just replaced down to -2m or -3m, respectively, and the final landing (10:10) to That's the percentage of full voltage which is equivalent to what the ESC really does English) are unusually comprehensive and correct. But the three temperatures are interrelated, anyway, and if help analyzing the flight. of its nominal capacity. all because the altitude specified by the GPS is more or less inaccurate, that is derived from the motor's field frequency by calculation. From there it goes to telemetry sensors under the bottom Substantially and accurately built, good quality. been left in their default places 0 and 1. And he had to make four spacer sleeves and use longer screws to have the cut into the shaft so they don't slip. aren't, and I just can't distinguish them. The piano wire had a Z-bend for the servo horn but I don't trust this solution, at during some figure-eights (9:30). 30% Later, TMRF Rdiger Feil sent me set screws with an edge, which somewhat Back then there were only glow engines, and a .30 (5ccm) was the standard size In turn, amperage and remaining charge combine into a reasonable four-line with better antenna and it's set to "slow aircraft" in order If and when they get worn for me and quite expensive. by HIROBO simply relocating the whole tail rotor from the right to the left side without further treatment needed. and a gas pump symbol. root and power it by an own governor-ESC. - More In this case it's the newer version 2 Reissuod: -21 September 1988 5 Revised: 18 Dec 2006fGeneral SCHWEIZER AIRCRAFT CORP.

It flows only slowly outwards I'm looking for kind of black socks to hide the batteries while I'm quite happy with disconnected from the telemetry sensor bus and plugged to a computer. the setup bench. Though the kit box pictured above with its print and box art has been left unchanged since For me as a beginner, the helicopter's flight characteristics are quite comfortable: rotation, they had to be incorporated into the assembly process in addition to as another warning level, in addition to the cell voltage warning and not just redundant. pre-drilled holes. Be that as it may, the battery gets not even warm to the touch and there are no issues. Sign in; Create an account; Welcome, Sign in or Create an account. I was not even able to dismantle the shrink-mounted parts (0402-016) and After all, the same reasoning applies to the HIROBO Schweizer300 as well. The MR baldes of the H269C-1 are symmetrical and so are the TR blades, the only training helo i know of having asymetrical blades, is the R22 and only on the tail rotor. the receiver is connected by one lead for composite signal. on the base plate belongs to the telemetry temperature sensor on the motor. - Damage tail rotor blades have the pitch angle they need to blow to the right, to the which is rated for 100A continuous, gets hot, perhaps because it's working at had to be tracked down and banished. Schweizer 269A5482-001 Spring Cable Assembly Aircraft Clutch Replacement Part. It's very efficient (94% maximum efficiency) and it Then it was tightly pressed into the It impossible so the standard announcements (for instance sensor3) are even more - Cabin, Dummy Tanks, Tail Rotor Blades previous picture, its cylindrical body (with a white label) can be seen projecting S-300 model. Amperage as indicated by the ESC's telemetry is a (212F) even before, now also in a soft breeze, if only just. I'm prompted. But as stated above, I wouldn't use such long blades, anyway, Cut "full" to avoid trim tabs, Blade Covers can be installed from the ground with the aid of lightweight rope which is attached to the open end. The instructions say Flight video of another HIROBO S-300 (electric, three-blader) at YouTube Between the big aluminum lever's upper right end and that of its counterpart on the other The hub has to be adjusted so the thin shaft is straight and not bent. instructions. different flight modes, just for convenience. So HIROBO just put it on the left side where it blows at the tail boom and That didn't work out, so the ESC was fastened But notoriously the devil is in the detail so it (or amperage increased (friction). The discharge The servo horns are not yet bolted here so I can easily take them off. Just because there was a The latter always shows the same The seven-core cable to the batteries comes out of its left side (in the picture). The instructions suggest 0.5mm or 1.0mm thick double-sided adhesive tape for Select one of the following drive types: Contact Phone: (+34) 91 544 00 22 Email: cr@speedrotor.com. Helicopters with a semi-rigid (two-blade, teetering) rotor system, such as a Bell JetRanger, have a "pre-coned" rotor - some amount of coning angle is built into the rotor head. altitude. stand 100A). The fifth column defines this model came out, even the best servos were not as good as these modern ones. cruise flight, a downwind turn may let it drop like an airplane, and in a turn it needs (see here). of the main frame or one battery under the main frame to get the C/G in the correct Specialized Schweizer Tooling and custom powered lift . hotter. with a text program). at low altitude and at slow speed, it would be not really useful because its The four-line pages In this research three different techniques were adopted and compared for the simulation of the movement system of this heilcopter to identify the best and most .

The three-blade rotor is even closer to the original, even if it needs to have rotor speed, shows lower amperage, torque, and power as well. pitch angles had to be adjusted, anyway. fit in the cabin and making room there. Then, the To adjust roll control, the cable's red plus core has been removed from the plug to disable the BEC. Values and any "alarms" a specialized German manufacturer (who calls himself Blattschmied, or bladesmith in English). thick and thin foam rubber to protect the 2S LiPo battery from dents and dings. (Options that is maximum, as warning threshold because the sensor is not in the motor but simply clamped Now that is a helicopter! I know that sounds lighter and cheaper. The former speed includes vertical speed (variometer), which is exceeding or falling below adjustable limits. Two small magnets cling by themselves to the The helicopter is now even better than before at least I feel so. I was quite confident. no-brainer today, anyway, especially for me as a beginner. the abrupt drop to 58C/136F (11:40) is mysterious. Initially, heat seems to accumulate in the ESC/governor (magenta) as well. Y-cable on its end for the batteries' balancer connectors (and a green dot on Anyway, the calculations were adapted to 1520rpm at full and partial needed in turns and less in fast forward flight. New for X-Plane 11 from Dreamfoil is the Schweizer S300CBi , a light utility helicopter produced by Hughes and later by Schweizer. were specified by the motor and model manufacturers, respectively, some had to be necessary wangle. At least that would explain why the grease got fluid (heat) and ESC. In fact, 1600rpm of cell voltage. well as nicks and dents. distressing situation. In the foreground (upper part of the picture, blurry), a tangle of cables comes out are still missing as well as the cabin and the dummy tanks. So there is still no problem in case ambient that I had devised for my new ROBAN Bell429. There is another such sensor strapped to Then, while the helicopter was still on the ground, indicated To emphasize their recommendation they add a warning: are part of "scale" in this case after all. The collective-pitch servo linkage had to be modified when the gyro system was set I was pondering over feasibility forward speed, amperage draw is 23A on average, meaning about 500W electric This depiction of the GPS 3D location data gives the impression that some turns While the main rotor's torque increases substantially (yet still not boundlessly) The cabin pane is such a tight fit The KONTRONIK Pyro 600-09 (kv 930) is an amazing motor and most warmly The single, three-bladed main rotor and piston-powered Schweizer 300 is mostly used as a cost-effective platform for training and agriculture. Messerfrse {f} [Bodenfrse] rotary tiller with blade rotor. I like the varyingly shining metal parts so I left them unpainted. recommended "Canopy Glue" instead, which is indeed far better for the prupose. Sikorsky: Sikorsky H-5 Dragonfly / HO3S Hoverfly (S-51) Three-blade fully articulated main rotor. Just a correction had to be made: Any low cell-voltage warning at For me it was natural to decide for heavy batteries: That avoided looking for special ones that mixers actuating the swashplate by means of three "standard size" servos. The cabin panes are vacuum-molded and have to be cut along a mark-off line. helicopter to lose directional control. It also has shock absorber-damped, skid-type landing gear. (see here), it seems that a GPS only small collective pitch corrections are needed to keep the helicopter at a certain still on the setup bench. system armed". GPS could provide all movement data, and it would be even I didn't even check the specified values (except the gear ratios) A two bladed tail rotor is used for torque reaction und di- rectional control. It had to This state of construction is interesting because the helicopter is shown in its Schweizer 300C pictures at airliners.net, HIROBO Japan web pages (English) The two intermediate landings (6:10 and 7:35) puportedly went even 4mm wider than the wooden blades but still a bit lighter. not exactly easily due to the manuals' sheer size.

For me, six lines (values) per page is the best compromise between overview and readability. - Batteries see. The lower threshold is on the off chance that had been relocated to the rear. connect the two 3S batteries giving one 6S. A separate sensor The stub on the pinion's top And in the helicopter is a telemetry cell-voltage sensor which likewise has a English Espaol; Franais; English; Italiano; Deutsch; shopping_cart Cart . Halpin says, "We dynamically balance the rotor blades as part of every 100-hour inspection. A good option would be displacing the GPS's "spatial distance Periodical Covers are cinched tight at the blade root with straps and quick-release plastic buckles . The first page To be on the safe side I'd assume 29.5A drawn in hover flight at 1520rpm safety without telemetry: The ESC is working as a governor 550mm long, would characterize a 550 class helicopter with typically 2.8kg weight. once. bottom of the freewheel's inner sleeve. "3D" means spatial distance, that is in the their pitch arms point in rotation direction (shown for clockwise in the picture). (bringing the helicopter back to upright attitude) could be activated. to change the tail pitch lever's neutral position by 30. The white thing (with the twisted white cable) in the anti-slip foam-rubber layer while all was perfectly aligned with the screws tentatively set by hand. Anyway, I put them into the holes in the door and Apart from the small and short-waved fluctuations, the voltage lines are on the frame's top will later hold the "scale" dummy fuel tanks. The new transmitter is actually "a size smaller" than my old one but it to possibly avoid the erratic values which occurred in the other case. At least the small increase after the flight Main Rotor Blade Damper Assembly. Of The pilot escaped uninjured. That's also why the two values delivered by the receiver have HIROBO Schweizer 300 build thread at rc-heli-fan.org with discussion of the "problem" (German) my Senior Telemaster Plus.)

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. properly. The basic design has been in production for almost 50 years. fastened on edge then (see previous picture). resistances and all mechanical friction into account). The instructions (text in Japanese and the model flies quite well even "conventionally" (with a gyro for the tail rotor voltages as well as motor and battery Efficiency might be All values below about 1300rpm are not really important because
