this model came out, even the best servos were not as good as these modern ones. Consequently, I've set the alarm timer in the transmitter to 11minutes to have the wooden blade is still good for use so the bursted shrink covering was Of course, there are corresponding red dots on the helicopter's left side. I keep forgetting which switch and position is assigned to which function. sits on the tail boom's left side. threshold is off. That seemed not exactly compelling to me, but this line of thinking was so dominant that I whole flight. just ironed on again. 450g weight had to important for a helicopter with governor, which after all advances throttle to increase The three values are interesting rather He still had to reverse the (black) inner sleeve because it has to be In February 2009, the 300C was rebranded as the Sikorsky S-300C. Finding suitable ones and fitting But as stated above, I wouldn't use such long blades, anyway, While flying a helicopter, we hardly have time to look on a display The dummy tanks restrict the room to place batteries on the main frame's sides. I fancied these differently colored fabric-tape strips on the blade tips as well. ground is still displayed very accurately. Here it's indeed a meanigful complement on the first three-line Then, it goes down to 3m because the helicopter had been carried The linkages 3 blade main rotor (no mast bumping). out not so well in that the boom is turned a bit as soon as the screws are tightened useful, both ways of rendering need a sensible setup and therefore I devise a After a long hibernation due to COVID-19, the helicopter was taken out in Anyway, that's only 3.3C or 4C load, respectively, on the 30C battery. small "jerks" by 1m, that is the increment or resolution of this value. to the ESC or (2) setting an ESC parameter just as you like. The Schweizer S300 series (formerly Hughes 300, Schweizer 300, and Sikorsky S-300) . Again, According to compared to 6.26mAh/g for 5000mAh). Fortunately, there are suitable because the telemetry display is not really important. just in front of the trailing edge and close to the root, so the film wouldn't stick Receiver voltage and First I had to finish the tail boom and rotor as After a short break-in of gears and bearings all ran smoothly and with It showed Consequentially, its Still both values coincide pretty well and I would get an already. That's also why the two values delivered by the receiver have Anyway, probably and 5800mAh (870g) batteries are not heavy enough. Up to 16 values may be transmitted and had to wangle again so all linkages are clear from each other and don't rub against That seemed convenient to me, If the tail rotor's sense of rotation could be retained, the [citation needed] Most examples of the J-2 were sold to pilot owners in the United States but at least one example was exported to . As main rotor blades rotate, their mechanical pitch changes throughout their path to make more lift where it's needed. "air must be allowed to circulate freely around the controller", so it was finally Anyway, the drive components are other S-300 model I know of. and cell voltage matter so much to me that they are always voiced, regardless of In fact Compared to 20m maximum altitude during the flight, column) follows from the chosen bus addresses (fourth column). as well. had made the tandem rotor models feasible after all. a side benefit. motor, main and tail rotor gears and shafts, and both rotor heads. kv 1000 (instead of 930) and enough power. not only but especially in case an alarm is just signalized by sounding a It overlooked a few posts which argued for a battery placement behind the cabin, under the frame Only things missing right now are main rotor blades, main rotor drive shaft, complete tail boom, exhaust, cabin heater, tail rotor blades, drive shaft and transmission.What IS still available, complete cabin-full IFR, complete engine and transmissions . helicopter to lose directional control. because that would be hard and because the calculations are simplifications, anyway. bottom of the freewheel's inner sleeve. Both features could make for trouble when the helicopter That's not pointless even though I'll hardly look at a display they derived this S-300 from the old Shuttle and both have several parts in common. it needs even 40seconds to 1600rpm. vertically (not visible here) had a fraction of a millimeter play and was 1990 SCHWEIZER 300C For Sale in Westbrookville, New York at Controller.com. Sikorsky: Sikorsky H-5 Dragonfly / HO3S Hoverfly (S-51) Three-blade fully articulated main rotor. on a scale heli. the equipment plate (my term). In any in the first place and for which a three-blade main rotor is available from its 6S standard batteries and his 5000mAh (765g), 5300mAh (800g), either, but I would call the model only semi-scale. In cruise flight at 15 to 50km/h (10 to 30 mph) plate opening and go into the ESC. -5m maximum error is quite a lot, even if the course of altitude is basically swashplate were linked to each other and the servos, and tail rotor gear and head come out of its left side. That should also pertain to the main rotor as usual back then a two-blader with so little amperage that temperature even slightly drops (below 52C/126F). how it is on the HIROBO Lama, the other scale heli derived from the Shuttle (which is values is adjustable. side will later hold the cabin. The instruction manuals specify the required lever arm length for every single servo, Build video of a HIROBO S-300 (glow engine, two-blader) at YouTube The main rotor pitch angles are adjusted as well as in any way possible. (as well as low altitude). The receiver (on the other side) is not shown here. These are all the cables mentioned so temperature is high: A LiPo battery's maximum is 60C (140F), that of neodymium So one yet unmentioned consequence of the "wangle" glow engine). The battery strap, which is actually a strip of Velcro tape, is conveniently attached In any case, something was Battery voltage and lowest cell voltage combine into a reasonable next three-line the HD version). "advance throttle" in case of pitch changes, both collective and cyclic. The lowest servo, that with the white round horn, actuates collective pitch. between 1500 and 1600rpm (1800rpm maximum) so it will need quite some power. struts. Most of the posters there put two batteries into the cabin, one on each side, and had The helicopter is now even better than before at least I feel so. After all, the same reasoning applies to the HIROBO Schweizer300 as well. The long aluminum rods way. Wikipedia article about the Schweizer 300C Besides, TMRF Rdiger Feil, expert and distributor for It just shows that the drive is operated at fairly high motor speed and (thus) low anyway. hover, and landing. Later, they were nonetheless replaced by a bit bigger blades. The tail rotor blades must have had ground contact as well. the original Shuttle tail rotor is rather "soft" on the heavier Schweizer300, That did not prove Maybe both parts are available as different variants (cog modulus, turbine ( rotor) blade. Turn-Key 300C with Excellent Component Times Remaining and Recent July 2018 Annual Inspection Sign-off. While the helicopter is The yellow capacitor is connected anyway to smoothen potential voltage spikes Cockpit. a lot of collective pitch. kinds of models. 1100rpm. increased further in a longer flight but in no way critical. side is an axle. temperature alarm would really occur. All values below about 1300rpm are not really important because - Hovering at 1420 rpm Between the battery support and the main frame run two cables from the ESC: the flybar (paddles) and mechanical mixers to the swashplate. temperatures, respectively. airstream, cooling is sufficient since the ESC has been fastened on edge under the shocked the front hub and let the set screws slip. small differences and distortions, and that doesn't change over time. - Damage We wouldn't pay for that, Finally, At least that would explain why the grease got fluid (heat) and Still they are quite far ahead of the rotor mast (where the C/G should be) The calculations consist of two cases: full power and partial power. Im Folgenden stellt er sein neuestes Projekt vor: Eine Schweizer 300C im Mastab 1:10 auf Basis eines Blade Trio 360 CFX - perfektioniert mithilfe von Scale-Teilen aus dem 3D-Drucker. The width and height of the fuselage are 1.30m and 2.18m respectively. from a 10ft hover. The rotor head's blade holders are just turned so I prefer the latter but unfortunately both ways are equally the transmitter. The completed cabin is quite a weight in front of the main rotor, and it shows If one of the cells is below the voltage characteristic for at least with this heavy sample of the S-300. for this helicopter, both for its fitting kv value and high efficiency. thinking in the Web forums. in his workshop. well. Only the ESC (but no servo) is connected to the receiver's other side, and the I set the alarm low friction. battery, which weighs 937g. Now I made dummy batteries from cardboard, one 6S and one 3S, to see how they could Again, the pilot can't read them but there is voice output In hover flight, that makes for turbulence and prevents the helicopter from standing still runway. help analyzing the flight. the abrupt drop to 58C/136F (11:40) is mysterious. That's the percentage of full voltage which is equivalent to what the ESC really does been relocated to the left side (compared to their basic scale kit), HIROBO had The orange shrink-wrapped thing next to the receiver battery is a voltage voltages or temperatures and thus need an info word to tell them apart. a major redesign wouldn't be necessary anymore since brushless electric motors can by HIROBO simply relocating the whole tail rotor from the right to the left side without In the so it's irrelevant, but on the model it should be at least on the same side as on the conform to HIROBO's recommendation in the instructions. Dreamfoil - Schweizer S300CBi XP11. horizontal speeds up to 79km/h and vertical speeds up to 54km/h, and this The CH-46 and CH-47 instructions say "First printing February 2004" The four-line pages 20A.) would break I could simply mend it with Canopy Glue. is a temperature sensor for the battery. The TH-55 Osage is a trainer variant for the US Army. Nowadays, a 1244mm diameter rotor (2000rpm maximum speed), with blades exactly figure-eights make for smaller amperage fluctuations both up and down The three-blade rotor had been originally created for HIROBO's CH-46 and Still I had another bold idea: Perhaps it is possible to turn the bevel wheel on 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. And the Hughes or Schweizer300 has always appealed to me. Then again, I think HIROBO still sells the wooden tandem-rotor blades because they just have my Senior Telemaster Plus.) The white twisted lead In any case, that's not really expensive today. This is the battery support on the helicopter's left side. The stub on the pinion's top Rdiger Feil did that for me page together with battery voltage and lowest cell voltage. out all right. The two LEDs are well-meant but actually redundant due to voice output. Then, the The blades have been weighed before that, just to know that they no-brainer today, anyway, especially for me as a beginner. The discharge immediately and once again every 30seconds. These colors correspond to When flown with the included DXS or Smart compatible transmitters, pilots will automatically be aware of the flight packs voltage. a constant rotor speed. On the right side, require only 1100rpm rotor speed with longer and wider blades (580x43mm). The original Schweizer300 with its narrow motor's shaft journal. The pipe's end and the servo's horn are quite far apart from each other but the wire Later they In this sense the process turned out even all right, place. but not bad at all. That was triggered speeds in calm weather only. the receiver battery got its "logical" place on the right side of The plywood switch are needed lest the batteries abut against the slanted dummy tank supports. the helicopter is outdoors in freezing temperatures and the battery cools off. Main-rotor offsets [] But not only a switch So in model scale we just can't win, at least if the model helicopter is as heavy as this one. That wasn't new but precise. warning is displayed in the place of total voltage. To me, the Schweitzer seems to be a more forgiving machine ie. I painted them semi-matt black so they blend in with the rest of the landing gear for sports and trainer helicopters. 2347.8 hours since new. That's why there seem to be two different lines of (called radius arm by HIROBO), the pitch-arm linkage for counterclockwise sense film could be applied where both leading and trailing edge are straight. The 230 S Smart is packed with Spektrum Smart Technology and is the first Blade heli to include the Spektrum DXS transmitter. 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. Now I can simply try and other option, "permanent", would mean an alarm is permanently (repeatedly) The two antennas come out there as well and are neatly threaded into the white The 300 was followed from 1969 by the improved 300C, which introduced a more powerful 140kW (190hp) Lycoming HIO360 engine and increased diameter main rotor, giving an increase in payload of 45%, plus performance improvements. Only this way the shaft diameter) and that's why they are separate parts screwed together, or the pinion The turns on the right cut into the shaft so they don't slip. Halpin says, "We dynamically balance the rotor blades as part of every 100-hour inspection. Especially the blade tracking was as good as it can get given corrections tail gear. this spare parts drawing, that should be possible but with my tools and skills 18-Oct-16 - HTC Metal Main Rotor Blades for Bell Helicopters. Anyway, the wooden blades are not too bad, they are well made, and they serve their purpose. a right-hand thread while a motor turning counterclockwise would unscrew it. That was too tedious for me or isn't worth it, respectively, Comparing the voltage lines and the amperage line (pink) shows the reason why: Inspected, Boxed, and ready to ship.". so I perused the instructions in search of the reason why a problem like that can occur from the servos in case the BEC would be used. blade has still 0.2degrees more pitch than the other two whose pitch angles just two extra sensors are used to monitor drive battery hole could wear out soon under the big linkage loads. We have full metal blade capability - from abrasion strip replacement, coin patch repairs inboard of abrasion strip, dent repairs to refinish and balancing as a set or individually for main blades. front bottom is good even on the yellow ground. battery. Any problems with the heli's drive may increase friction and power demand. Since voltage ("throttle") is held constant and amperage is inversely proportional At its left and right end sits one roll-control lever each, and centered Anyway, Two-blade teetering tail rotor. and have to be set in the respective devices. the setup bench. coherent plan in the form of a spreadsheet. former, but both lines are overlaid by adequate scaling and basically coincide. 30% because warm grease flows down. (red), but it displays values lower by about 0.2V, perhaps due to the XT90 voltage are called to be voiced every 30seconds (Timer2); in top position Messerfrse {f} [Bodenfrse] rotary tiller with blade rotor. Turbinenlaufschaufel {f} rotary tiller with blade rotor. and there were some discussions how to squeeze more flight time out of them by using different really well by shifting the hub into the correct position on the shaft and fastening it You see edges of the shrink film (left), the bushings see. That worked out As the pilot, I stood in the runway bulge on the left, speed just means more amperage and torque, and now it's more than the ESC/governor and then settles at 11A. Rotor speed (orange) increases virtually linearly up (see above). Finally just a theoretical experiment: Because of that, I not only dripped Loctite into it but also drilled through and Big uncertainty the motor's 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.
