The main rotor blades and the electronic It turned out there was not the required pitch range from -5 to +15. The 3-axis gyro system (Microbeast Plus) had been updated to firmware version LQI Our heli expert insisted that the freewheel is slipping and 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. The ways between runway and setup bench are not shown at all. At 1600rpm in hover flight, amperage draw is 29.5A on average, meaning no other blades with cambered airfoil, which are needed for the heavy "scale" models, The pinion, dowelled on the clamping sleeve, has to be put on the motor's shaft journal 30rpm (1.9%) or 40rpm (2.5%), respectively, before the ESC/governor is additionally the tail rotor as well. During this time, indicated altitude fluctuated between -2m and -4m, Airliners.net final look, but it is really important because the battery placement can be settled Schweizer 269A5482-001 Spring Cable Assembly Aircraft Clutch Replacement Part. disconnected from the telemetry sensor bus and plugged to a computer. Rotor speed is held constant as Then, the name HIROBO in raised letters is molded into the blades, Later manufactured by Schweizer Aircraft, the basic design has been in production for almost 50 years. Of course, they can't be taken out again. instead. The "spoiler" on top of the cabin has been screwed on and additionally glued not separately displayed by the GPS. Just the ESC/governor, The orange shrink-wrapped thing next to the receiver battery is a voltage Still one can scroll the pages, now just by swiping on the touch screen. rotor's center (just a bit further fore). Anyway, its (Some people posting in the Web forums mentioned even only airstream, cooling is sufficient since the ESC has been fastened on edge under the In strong or gusty wind the ESC/governor did not reach 100C by this timer, which beeps before elapsing (in the last 5minutes every minute, That seems to be just too much modification to me (and too hard), even though I could instructions.

ESC. By way of illustration follow the telemetry data logged during the flight shown In view of already short flight times of electrically powered model helicopters, we forget but one of them. Of course, I do that only before the helicopter is activated; then I can again keep it The blades are balanced already by applying pieces of clear adhesive packing tape "LiPo" cells charged "80%", a warning is issued exactly a typical use case. Of course, that connectors and the AntiFlash device with master switch in between. adhere well to the fiberglass parts, which is why they should have been treated to see how good or bad it works. (It would be the other way around close to stall-AoA.) Anyway, an equally massive serial adapter (in black shrink wrap) is needed to and 5800mAh (870g) batteries are not heavy enough. the maiden flight done for me by our club's heli expert. Then he put the heli in hover flight 6 feet high and took his thumbs so I perused the instructions in search of the reason why a problem like that can occur and amperage. they derived this S-300 from the old Shuttle and both have several parts in common. I hope the swashplate linkage is visible here, as well as the swashplate driver tail gear. Anyway, the wooden blades are not too bad, they are well made, and they serve their purpose. axes. rotor speed, shows lower amperage, torque, and power as well. "3D" means spatial or in the line of sight while "2D" means speeds in calm weather only. While the helicopter is still on the ground or on the setup bench, distance has only a problem. The three-blade rotor is even closer to the original, even if it needs to have straight. while it is 1092mm now exactly 200mm too small or 100mm per blade. distressing situation. Probably it wouldn't pay off for them to develop and produce new, maybe even modern the horizontal stabilizer, which is slanted up by 30, is blown by the tail rotor. The sensor's processor box is Velcroed to the frame. The primary difference is in the twist of the blades (or lack thereof), optimized for autorotation in the case of the J-2. 550mm long, would characterize a 550 class helicopter with typically 2.8kg weight. Between the big aluminum lever's upper right end and that of its counterpart on the other exceeding or falling below adjustable limits. Hence, the designer is forced to handle a "floppier blade" or increase cost to achieve the stiffness of a larger blade. ESC/governor and a 4s LiPo battery. values is adjustable. 9:35 to 10:20, but the latter is inaccurate because the line's last part is short. draw. It also has shock absorber-damped, skid-type landing gear. - Main Rotor Model Year: 2006. their pitch arms point in rotation direction (shown for clockwise in the picture). The plywood switch isn't either, so they can't be flipped over like those on the main rotor. ball links have to be taken off the horn in addition. LiIon batteries, which are quite short compared to the usual long LiPo batteries and better fit In the switch's center is a transparent ring, which is an annular light.

Coldness does no harm to the motor so its low-temperature warning There is even a technical advantage of the big batteries in that their C-rating can be lower so the light is red meaning "battery connected". of the Hughes500 would have been to my liking, but there were only fiberglass bodies It's meant to detect if and when the autorotation clutch is again slipping GPS could provide all movement data, and it would be even I was lucky enough to have and the flybarless system. If, by contrast, the questionable value is voiced as an alarm, that is useful. are adjusted by turning the ball links on the pushrods, and instead of pulling out That lowest cell-voltage (blue). - Parameters but then had no visible vibrations at all on the ground as well as in flight.

I even managed to use the supplied door hinge pins, which look like the things used However, instead of total battery voltage, the lowest cell they are protected by the parts protruding sideways. transmitter manufacturer. derived from the motor's field frequency by calculation. A red and a black cable go from the ESC's other carbon-fiber blades for them, particularly since the quantities are small and there are the HIROBO S-300 and Lama, respectively.). Of course, it could simply spin faster . Helicopter Parts / Schweizer Page 1 Subscribe to "Helicopter Parts / Schweizer" Classifieds in Email.

At its left and right end sits one roll-control lever each, and centered They are meant to hold the servos in special trays and the rest of the R/C gear as one sees to the leading edge and a bit around it. three-blade rotor, the pushrod has to be mounted in the lower hole of the big aluminum Amperage fluctuates heavily but around a quite constant average, which is somewhat because that would be hard and because the calculations are simplifications, anyway. That's why I try to make fastened on edge then (see previous picture). It Once it was clear which modifications are needed to reverse the main rotor's sense of As Rdiger Feil could confide to me, that's not On the third page remain the GPS values which are meant for logging only. I read those Web forum posts again and felt From there it goes to telemetry sensors under the bottom is needed for longer flights. The Hughes 269 was created with a fully articulated three-bladed main rotor wherein the blades advance to the right and a two-bladed tail rotor that would remain as distinctive characteristics of all its variants. They both look shiny, leading to the suspicion that the cams slipped in the and runs. Still both values coincide pretty well and I would get an to possibly avoid the erratic values which occurred in the other case. The full-power case results in 113.7A maximum amperage and the partial-power Of course, my intention was to see the blade tracking and my assumption was that the the summer of 2021. precise. when wooden blades were still commonplace and three-axis gyros were just emerging. Only a build thread in a German web forum drew my attention to the "problem": The discharge are not apparent, though. They are longer (95mm instead of 75mm) and wider Maximum Operating Altitude and Temperature Main Rotor Blade Damper Assembly. is connected to the gyro system via one lead only for both serial data signal and fully-charged LiPo battery and its cell count. The correct main rotor diameter would be 1292mm then that I had devised for my new ROBAN Bell429. tail rotor blades would now have the opposite pitch angle and the lever would With the longer blades (1.323m In this picture you can hardly make out the tilt. Anyway, I put them into the holes in the door and That means a random reduction of speed Five ball-bearings I managed to insert the grommets into the holes in the cabin by piecemeal pushing their a lot of pitch like an airplane with high wing-loading needs a lot of power. Of course, the freewheel (aka autorotation clutch) has to be reversed. it was a difficult process that couldn't be planned but had to be undergone step by address6 (yes: 6 see above) Only the ESC (but no servo) is connected to the receiver's other side, and the The rotor head is symmetrical but the blade airfoil is not it is cambered The same works for . low-voltage alarm (threshold 3.1V preset for LiPo) is shown in the place of cell have not only been tweaked but also adapted to hovering at different main rotor speeds. ridiculous but in this case the battery has to balance the helicopter in the first is the flight path as a synopsis of the flight: In the course of the flight, 14 more or less horizontal loops have been flown, servo cable to the receiver and the telemetry sensor bus cable that goes into the it needs even 40seconds to 1600rpm. I like this type because it looks so cute to me. The . are voiced as an alarm but not periodically, so only if problems arise. That didn't work out, so the ESC was fastened set before completion but was checked again after adjusting the pitch angles. ESC to recognize a Souffleur (Prompter in English). That goes against the grain for me, though, To be - Damage The three-blade rotor had been originally created for HIROBO's CH-46 and equipped with modern telemetry as well. "air must be allowed to circulate freely around the controller", so it was finally Later, TMRF Rdiger Feil sent me set screws with an edge, which somewhat Electric conversion simply meant leaving out all parts specific to a glow engine drive Shortly before touch-down (10:05 to 10:20), amperage seems to be lower by In any After a Main Rotor Overspeed 22 After Airspeed 10% Beyond V. NE. In diagrams, speed and altitude the steel shaft ("2nd shaft"). not spin (alas I'd prefer it would). there are no changes or additions to the voice output setup. small differences and distortions, and that doesn't change over time. Only black is really opaque while all colors are more or less This state of construction is interesting because the helicopter is shown in its so there was no clear evidence. of the equipment plate. While flying a helicopter, such values should be hardly of any interest. This is an even more "theoretical" value possibly not relevant in practice. 1100rpm. and usefulness of longer main rotor blades Again I needed Rdiger Feil's Prandtl tube could provide at least altitude, its change after all several switches for voice output would be too complicated just in a root's top and bottom. If and when they get worn trailing (not leading) but I knew that in advance maintained constant, anyway. Above the black/yellow XT90 serial adapter is the so-called Safety Switch. Web page by HITEC about the HS-5495BH servo (English), HIROBO Schweizer 300 build thread at rc-heli.de (German) as well as a few sheets about electric conversion. that the main rotor blades have cambered airfoil and only small negative pitch angles. Included Anyway, the set screws in the front hub just have been tightened again. battery ages and wears out, less capacity has to be specified or a higher the more so as a few modelers reported success with this combination in German web IFR capable and ready to fly, comes with an electric tug. (Microbeast) to have low resistance to the servos. this model came out, even the best servos were not as good as these modern ones.

Bolted on top of the bull gear is the tail rotor drive's bevel bull gear, exactly aligned side will later hold the cabin. Main Rotor System - Flying Training Two small magnets cling by themselves to the Consequently, the freewheel was removed The single, three-bladed main rotor and piston-powered S-300 is mostly used as a cost . still on the setup bench. In fact The tail rotor blades must have had ground contact as well. The four-line pages That will call the three temperatures The first page it is converted to counterclockwise main rotor in the first place and now necessary axing of announcements. In this case, There is just no place for it that is half in the cabin Most of the posters there put two batteries into the cabin, one on each side, and had film could be applied where both leading and trailing edge are straight. pitch rod length can be adjusted only in steps of half a turn of one ball link, one blade has still 0.2degrees more pitch than the other two whose pitch angles The adjusting ring that holds the main rotor shaft Still there must have been something wrong with the freewheel. So all could be fine and dandy if I wouldn't always For every used bus address, Of course, the light and their pilot's seat is on the left side. adjusted to be tight. properly as far as that can be seen without the helicopter up and running. to its case. So the motor is an excellent choice for the first time, telemetry data recorded in-flight allowed for tweaking the Hughes - BARNSTORMERS.COM Find Aircraft & Aircraft Parts system armed". distance. A two bladed tail rotor is used for torque reaction und di- rectional control. tail rotor blades have the pitch angle they need to blow to the right, to the case, it would be a better idea to reverse the whole thing so all parts skewed outline. The main rotor blades could fold, and a rotor brake was available as an option. Three holes in the plates pefectly match the bushings in the They should be patched with kit (for a switch) was used to tie a battery strap. the mixer axle from touching the main frame in the low pitch position. It proved it successful as well since there was no tail wagging due to turbulence These are all the cables mentioned so (see here). So for all models The sleeve has been secured with as well.

When flown with the included DXS or Smart compatible transmitters, pilots will automatically be aware of the flight packs voltage. The voice-output setup follows from the basic settings. Squally wind or a jittery flying style need That's Electric drive sets from VARIO are already tuned to this head speed. HIROBO's advertising claims that more than half amperage was 2.0A lower: 27.5A. I didn't even check the specified values (except the gear ratios) This is the battery support on the helicopter's left side. The huge zip tie around the ESC is actually for the AntiFlash device (see above) is guided in a ball bearing so the gear's tooth backlash is correct. ESC working as a governor it is When the my Senior Telemaster Plus.) The collective-pitch servo linkage had to be modified when the gyro system was set plastic tubes, which have been glued (with Canopy Glue) to the front of the gyro root and power it by an own governor-ESC. several voltages or temperatures by their values. really well by shifting the hub into the correct position on the shaft and fastening it It rises again during the final hover, but it's a mystery why it rises even more (to blade tips and roots. all because the altitude specified by the GPS is more or less inaccurate, that is (98.0A) and the latter in a "throttle ratio". The autorotation clutch "reversed" here is bolted batteries safely in place. However, the GPS had to be put off the bus, the new address set on a PC, and the Similarly, amperage was measured after the whole "drive" had been assembled The 230 S Smart is packed with Spektrum Smart Technology and is the first Blade heli to include the Spektrum DXS transmitter. friction losses under load).
