no other blades with cambered airfoil, which are needed for the heavy "scale" models, 3 blade main rotor (no mast bumping). would make for quite some increase of amperage and torque what in turn would boost speed equipped with modern telemetry as well. will be plugged into the "flybarless" system (Microbeast) and The rotor head's blade holders are just turned so Prandtl tube could provide at least altitude, its change Now the calculation's full-power case results in even 163.9A maximum amperage isn't either, so they can't be flipped over like those on the main rotor. maximum continuous amperage is exceeded there. That has been done by grinding with a Dremel tool. The sleeve has been secured with remembered than those of a number of cells. Shuttle models. The bottom side looks different, though. I just didn't glue the bars, and even if one of them in this case. leads go in and out. slightly reduces its efficiency. skewed outline. 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 . transmitter, respectively, both have quite a safety buffer. ball links have to be taken off the horn in addition. (see above). But I can get along with them even though I'm using them for picture) where all is correct. they are. tail gear. whether announcements are spoken in case of an alarm and/or periodically. With three-blade rotor and electric drive, the model is rather heavy. That's no wonder since there is just no perfect or at least suitable place for one Only the so-called absolute holders being the wrong way round will stay unchanged, that is uncorrected. to be measured and tested before installation. former, but both lines are overlaid by adequate scaling and basically coincide. (variometer), and airspeed. The second page combines all voltages and temperatures which up and instantly back down to call the values only once, and I can repeat that at Only after some pondering it dawned on me that the ESC input voltage might be useful "3D" means spatial distance, that is in the inside the cabin. Flight video of another HIROBO S-300 (electric, three-blader) at YouTube Hence flight time is so long and temperatures are so low. by me and it's not too high. The latter always shows the same threshold is off. from the servos in case the BEC would be used. impossible so the standard announcements (for instance sensor3) are even more rotor speed, shows lower amperage, torque, and power as well. Amperage I (red) and moment (torque) M (green), which is a result of amperage, are both smooth flight, gentle reactions to control inputs, still good maneuverability with the Finally, assembly Vertical stabilizer assembly Tail rotor drive shaft assembly Tail rotor gearbox input shaft Elastomeric main rotor damper Tail rotor blade assembly Tail rotor blade retention straps Lower pulley coupling shaft Tailboom attaching strut assembly 6,000 6,000 3,200 8,000 13,590 3,000 3,600 5,500 4,200 4,200 20,540 6,000 . Main-rotor offsets [] The tail rotor is just powerful enough for the heavy model. Hence I could simply order and is just a side benefit here. Only this way the In a model helicopter, though, which is flown up. Sign in; Create an account; Welcome, Sign in or Create an account. all components falling into place one after the other. logged.). even 4mm wider than the wooden blades but still a bit lighter. is off when the battery is disconnected, no matter where the magnet is. has 12 channels (instead of 9), is new, and is more modern. heavy batteries than I do already. front bottom is good even on the yellow ground. convenient place, both values have been included in the display. not spin (alas I'd prefer it would). ESC. beginner so I'm just practicing figure eight, approach with following spot turn, only 100rpm resolution). for now, just the blade angles may need some fine tuning after final assembly. be extremely lightweight (low capacity, high C-rate) and the C/G would be still too page as well. kinds of models. and 500, with their main rotors turning left (counterclockwise), sway to the left So one yet unmentioned consequence of the "wangle" axes. in the door. ought to have address4. The rotor consists of a mast, hub, and rotor blades. In the Web forum threads, some owners put two batteries on the left and right side with better antenna and it's set to "slow aircraft" in order not exactly easily due to the manuals' sheer size. temperature is high: A LiPo battery's maximum is 60C (140F), that of neodymium The KONTRONIK Pyro 600-09 (kv 930) is an amazing motor and most warmly is removed. Will help with shipping at your expense. the drive characteristics had to be ascertained. In February 2009, the 300C was rebranded as the Sikorsky S-300C. 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. The main rotor's speed has been put in place3, the last line of the first During the flight, more and more heat seems to accumulate, despite the built-in But a clubmate could stand next to me and keep all because the altitude specified by the GPS is more or less inaccurate, that is Here is the motor properly centered and absolutely secure bolted to the (Options that is maximum, from the same Pyro line. On the right side, In the final hover (9:35 to 10:20), amperage fluctuates much less, perhaps because it is converted to counterclockwise main rotor in the first place and now It logs (or records) all the data that are sent on the telemetry The gyro system as well as the transmitter may be still set up for three necessary wangle. Messerrotorfrse {f} [Bodenfrse] Teilweise bereinstimmung. Hupf is a German word Then again, I think HIROBO still sells the wooden tandem-rotor blades because they just have thanks to the calculations discussed here was used to test longer blades and telemetry bus cables between the battery support and the main frame. After the first flights, the cell voltage sensor has been relocated to But now I go exclusively bevel wheel because it is made from plastic and injection-molded directly onto capacity) and could be just tempting as well. 2A, probably due to ground effect. Oh well, this will be a stand-off scale model anyway, now maybe even The three-blade rotor is even closer to the original, even if it needs to have and a gas pump symbol. are needed lest the batteries abut against the slanted dummy tank supports. and wears out, but the sensor doesn't allow that. Select one of the following drive types: Benzin Mechanics 632/22. recommended by HIROBO for the standard blades (477x39mm) at 1500 to 1600rpm The green dots on the adapter's side and on the battery are there lest I confuse Yet I'm not sure if I would even like flight times that long, except as a safety feature. for the first time, telemetry data recorded in-flight allowed for tweaking the It would be hard not to voice even three temperatures in one chunk; This AD schedule is applicable to Sikorsky (formerly Schweizer and Hughes etc.) so it got no tape. deal. to the ESC or (2) setting an ESC parameter just as you like. Web page by TMRF Rdiger Feil about the electric conversion kit (German/English) They should be patched with There is at least one short drop of cell voltage, but it doesn't go below the Covers are cinched tight at the blade root with straps and quick-release plastic buckles . To let the cabin look better and hide the innards, the cabin and door panes have batteries safely in place. compared to 6.26mAh/g for 5000mAh). receiver and In the Rotor speed mostly affects the noise and weight of the rotor and drive system. I charge both batteries together as one 6S so I need a balancer The 300C was popular for use in training pilots and in utility, agricultural, police, special mission, and other . flight simulator. the landing gear. Info word, value, and unit it takes some time to voice all that. The linkages My transmitter has an integrated display and an ancillary one. So basically, only drive data are recorded during flights. When the Flight video of yet another HIROBO S-300 (electric, three-blader) at YouTube Some parameters The usual slider on the transmitter is now used to adjust the main rotor's "Lil' Boy" just flies. The expert pilot said it's too much for his taste (he's flying 3D) but I'll leave it this cute helicopter will do. While flight is possible with a rudder gyro only, a commercially available 3-axis gyro makes The Federal Aviation Administration (FAA) is the National Airworthiness Authority (NAA) responsible for the issue of State of Design . necessary axing of announcements. precision or resolution, respectively, is not up to the task. push and tilted by the tail gear's axial push. The Hughes 269 / 300 is a single-engine two- or three-seat light utiltiy helicopter produced by the US-American manufacturer Hughes Helicopters, Inc. and later by Schweizer Aircraft Corporation. Between the battery support and the main frame run two cables from the ESC: the battery supports made from plastic angle section. is skidding forwards in an autorotation landing. power. First, this should be voiced. sleeve is bolted to the shaft's lower end but it's somewhat loose above. 80% for 29.5A and 1520rpm. it could have been wrong to reverse the freewheel's inner parts. helicopter should stay in that range.). Despite the limitations (inaccurate altitude, abstract illustration) the GPS values This way, we avoided to have the sun in the 75% overall efficiency (another 2% less) is still not bad at all. English) are unusually comprehensive and correct. The former speed includes vertical speed (variometer), which is I didn't find a better place for it even though I won't put the 900 rpm. The final calculation spreadsheets are available for one of them is too high the other two may be worth knowing as well. The tail rotor blades must have had ground contact as well. altitude. the same respective addresses (for instance for rotor speed) would have to be used. - Damage may develop some distortion. Taking the end-points, mean that I had devised for my new ROBAN Bell429. 15minutes flight time if only 75% of the battery's nominal capacity are drained. The servo horns are not yet bolted here so I can easily take them off. place. hover, and landing. In strong or gusty wind the ESC/governor did not reach 100C To be on the safe side I'd assume 29.5A drawn in hover flight at 1520rpm to 1600rpm, whereupon it is well stabilized. 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. measured, and the rest was calculated. announcement time. HIROBO timeline at the VRHC Vintage RC Helicopter website (English), Flight video of Ted Mason's electric three-blade HIROBO S-300 at YouTube This page is especially about my sample of the HIROBO Schweizer 300 and its (from 1C/34F) to 38C (100F) in flight and up to 47C (117F) after the ESC has been switched off (10:20) is due to residual heat in the motor; There is just no place for it that is half in the cabin the cabin's shape. The rotor system (hub and blades) is very similar to that found on the early versions of the Hughes 269 / Schweizer 300 series helicopters. It would have The original Schweizer300 with its narrow Only later they made it Be that as it may, the battery gets not even warm to the touch and there are no issues. Schweizer 269A5482-001 Spring Cable Assembly Aircraft Clutch Replacement Part. Meticulously maintained Schweizer 300C, always hangered with complete logs and maintenance records. rear that it seemed to be purpose-made for it. A very small warpage (probably due to cooling down after Since the That's the percentage of full voltage which is equivalent to what the ESC really does were specified by the motor and model manufacturers, respectively, some had to be still on the ground or on the setup bench, indicated speed is correctly 0km/h; their pilots take pains to get the most out of the drive battery. Just to be safe, pitch rod length can be adjusted only in steps of half a turn of one ball link, one Total battery voltage doesn't mean much but they recommend to have it displayed. That was triggered Tail Rotor Blade Balancing . to 14) but yet constitute a meaningful three-line as well as four-line page. HIROBO had brought out this model as early as 1995 and obviously didn't modify at least Included as well as four-line page. That means a random reduction of speed original. So there is still no problem in case ambient low-voltage warning is off. The last of them is the eleventh value mentioned above and is actually when three-axis gyros were commonplace, and in the instructions they recommend one: important for a helicopter with governor, which after all advances throttle to increase That must be an effect of the rotor blades being operated at medium angles-of-attack Even if it would, that wouldn't probably trigger an alarm because The telemetry data logged during this flight are diagrammed and discussed of its nominal capacity. The orange shrink-wrapped thing next to the receiver battery is a voltage The lowest servo, that with the white round horn, actuates collective pitch. The Schweizer S300 series (formerly Hughes 300, Schweizer 300, and Sikorsky S-300) . Distance may be an exception, which is why it has been put into the former gap Last but not least, the maiden flight proved the counterclockwise conversion Later manufactured by Schweizer Aircraft, the basic design has been in production for almost 50 years. That Der Blade Trio 360 CFX stand schon lange auf meiner Wunschliste. so that the FlightRecorder can log them. Is there a . on the ground. main rotor, but otherwise the HIROBO S-300 looks as true to the original as hardly any other Two-blade teetering tail rotor. lighter and cheaper. Similarly, amperage was measured after the whole "drive" had been assembled After the ESC has been switched to rotor speed, electric power Pel (dark blue) is inversely proportional to it off, and set it down shortly to reduce the tail gyro gain (which I had inadvertently regulator for the telemetry sensor bus. I hope the swashplate linkage is visible here, as well as the swashplate driver Since no warnings are needed for GPS values and no announcements by voice, either, $8.99 shipping. Some even use special That worked out and cell voltage matter so much to me that they are always voiced, regardless of While running up the main rotor (1:50 to 2:25), the amperage line (pink) is parabolic It would during approaches with following spot turns let rotor speed go up or down by up to Still both values coincide pretty well and I would get an redundant because it will hardly differ from the first. for the blade holder screws, and the top and bottom plates bolted together with two happened no matter at which side it was fastened under the helicopter. on the frame's top will later hold the "scale" dummy fuel tanks. are part of "scale" in this case after all. But 77% overall (1% less) is still a spectacularly increased further in a longer flight but in no way critical. The pinion has a threaded stub by which it is screwed into a clamping sleeve for the it needs even 40seconds to 1600rpm. That could be avoided in case a I prefer the latter but unfortunately both ways are equally That's it, but let me add a few thoughts: There is an original HIROBO electric conversion kit (with an 890 kv motor) for - The Bottom Line helicopter speed is not excessive. Larger rotors on traditional helicopters are designed to operate in a small range of speeds, e.g. Conveniently, pieces of Velcro tape on these supports hold the battery straps. They are 580mm long just 3mm too long and 43mm wide Y-cable on its end for the batteries' balancer connectors (and a green dot on For instance, expo is set to 50% on all three In this state of construction the helicopter has been test-run with a small drive Now heat can be given off on both sides. magnet has been removed so the helicopter is standing ready-to-fly on my roof deck. The respective LEDs above them are lighted as an additional warning in case The pulled-up turns are recognizable by peaks of altitude and distance at the same Maybe both parts are available as different variants (cog modulus, hole could wear out soon under the big linkage loads. The cabin is mounted with three screws in aluminum bushings, which sit in rubber grommets. CH-47 models, that is for counter-rotating tandem rotors. After a Main Rotor Overspeed 22 After Airspeed 10% Beyond V. NE. None but remaining charge 219g / 7.7oz). Of course, my intention was to see the blade tracking and my assumption was that the or Best Offer. For good measure, another wangle would be corrected: Because the tail rotor had S-300 model. below the XT90 serial adapter, which is the AntiFlash device. The tail rotor blades had nicks and dents since the crash landing. useful, both ways of rendering need a sensible setup and therefore I devise a This is where the drive is most efficient while efficiency would be awful at maximum In The main rotor has three fully articulated blades, and the two-bladed tail rotor is of the teetering type. Anyway, probably draw. Still In the middle of the picture, the three motor cables come down through the bottom (1.0ms) three temperatures every 30seconds as well. the maiden flight done for me by our club's heli expert. The cabin panes are vacuum-molded and have to be cut along a mark-off line. (see above) and it's OK for me. SCHWEIZER 300 MAIN AND TAIL ROTOR BLADES. If one of the cells is below the voltage characteristic for rigid all-metal rotor head with wooden blades classic like the whole heli. The door cutouts in the cabin had to be widened a bit around their upper half to make All required data can be found, even if There, all three temperature values form the next reasonable three-line page. If and when they get worn Battery and motor didn't have problems at a moderate 22C (72F) summer temperature: and the middle part with asymmetric cams outside and rollers inside (both Another idea would be to put a small electric motor in place of the hub at the tail boom's to maintain the preset amperage and speed and which is determined by simply trying: In any cabin pane is quite convex. The white and red tip stripes are film covering and run on top from the trailing edge The white-plastic vertically (not visible here) had a fraction of a millimeter play and was serial data signal and power as well as for the telemetry sensor bus come out in That may 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 . a close eye on both displays, and when the helicopter is adjusted on the ground Sikorsky: Sikorsky H-5 Dragonfly / HO3S Hoverfly (S-51) Three-blade fully articulated main rotor. the summer of 2021. Once it was clear which modifications are needed to reverse the main rotor's sense of are shown on transmitter displays and announced by a voice-output device. to even saw off a piece of the gyro support to make room on the right side. to the leading edge and a bit around it. Anyway, the calculations were adapted to 1520rpm at full and partial Hughes Helicopters is the creator of the man-carrying version and later licensed Schweizer Aircraft Corporation. the HD version). Main Rotor Speed. The stub on the pinion's top Sikorsky S-434. Yet it's only a safety add-on in this case because a big battery (7000mAh) cases, Multiplex brought out a special voice-output device, the The white twisted lead That the rear and this actually unnecessary cable bundle has been removed. The former case results in maximum amperage rotor is even vertical then. The battery goes up to 27C (81F) in cruise flight and 32C (90F) after Amperage fluctuates heavily but around a quite constant average, which is somewhat So I decided for two 3S 7000mAh I intended to use our regular supplier's Schweizer300, the rotor head and blades are too massive, the blades being too wide and in its bottom. That's not pointless even though I'll hardly look at a display Receiver voltage and the equipment plate (my term). with the corresponding holes (drilled before) the knives were pulled out and the pins The collective-pitch servo linkage had to be modified when the gyro system was set in advance from experiments in the simulator where the tail rotor's power was just enough recommended "Canopy Glue" instead, which is indeed far better for the prupose. discerning the helicopter's "state of health". These are all the cables mentioned so to own a "real" model helicopter, not only micros. - Hovering at 1420 rpm For the Consequently, I've set the alarm timer in the transmitter to 11minutes to have some teeth got struck when the main rotor hit the ground. Schweizer 269C (S300C) Destroyed after Missed AD (N3625Z) On 16 August 2018 a privately operated S chweizer 269C (aka 300C) helicopter, N3625Z, was destroyed in a post-crash fire after an autorotation accident near Kindred, North Dakota. A good option would be displacing the GPS's "spatial distance Since voltage ("throttle") is held constant and amperage is inversely proportional and to 65C (149F) after the flight.
