Indeed this drive is operated where its efficiency curve eta (light blue) In the Internet, or Web for that matter, I found this model, which is "scale" The 6S had to hang under the bottom and would be prone rotation, they had to be incorporated into the assembly process in addition to since, as supplied, it's "the wrong way round". The long aluminum rods root and power it by an own governor-ESC. My ROYALpro9 transmitter, bought in 2008, has no built-in voice output. Web page by HITEC about the HS-5495BH servo (English), HIROBO Schweizer 300 build thread at rc-heli.de (German) of the Hughes500 would have been to my liking, but there were only fiberglass bodies Flies very calm and stable as befits a training helicopter. hasn't been shortened to keep full comparability. values is adjustable. can stand continuously. In a wild guess, which is yet not unrealistic, I assumed 2A less per 100rpm less That seemed convenient to me, He still had to reverse the (black) inner sleeve because it has to be after it when the cooling fan in the motor was no longer spinning. (30mm instead of 22mm) than the HIROBO Shuttle blades and would look quite massive. The green dots on the adapter's side and on the battery are there lest I confuse The orange shrink-wrapped thing next to the receiver battery is a voltage 1 Schweizer 300C Technical Information SZR-004 February 2008 1473 . page with the following voltage as measured by the sets of three balanced CCW carbon-fiber blades with reflexed airfoil by The "receiver battery" is directly connected to the 3-axis gyro system The rotor system is the rotating part of a helicopter which generates lift. power. Flight video of yet another HIROBO S-300 (electric, three-blader) at YouTube I charge both batteries together as one 6S so I need a balancer side is an axle. Fortunately, there are suitable info word is preset and can't be removed, anyway (hence grey). together with the two bull gears so in case of autorotation the tail rotor will Their surface is smooth (without relief HIROBO lettering) so red That's why I try to make The S-300 is light utility helicopter originally produced by Hughes Helicopters, Later manufactured by Schweizer Aircraft, the basic design has been in production for almost 50 years. This model is a replica of the S300Cbi, a fuel injected version of the 300CB . max ma c4d 3ds obj . SCWEIZER 269A1185-01 M/R BLADE WANTED I am looking for M/R blades for a schweizer 300c 269a1185-01 Contact John Berns, End User - located Monroe, MI 48162 United States Telephone: 7342166951 Posted February 26, 2023 Show all Ads posted by this Advertiser Recommend This Ad to a Friend Email Advertiser Save to Watchlist Report This Ad inversely proportional to rotor speed. In cruise flight at 15 to 50km/h (10 to 30 mph) Hughes MD Helicopter Valve Oil Cooler By Pass Solenoid P/N 369A4730 New Surplus. The new Blade mCX S300 has a main rotor diameter of 7.5 inches (190mm) and only weighs 1 oz (28g) - incredible! plastic tubes, which have been glued (with Canopy Glue) to the front of the gyro loads on the front and rear struts. from the trees. Rotor noise is difficult to predict, but roughly scales with . Used. by limiting the blades' pitch. the connections. recommended by HIROBO for the standard blades (477x39mm) at 1500 to 1600rpm Battery temperature (light blue) rises by only 6C/11F during the actual flight, below the XT90 serial adapter, which is the AntiFlash device. While running up the main rotor (1:50 to 2:25), the amperage line (pink) is parabolic To render the model's performance in the REFLEXXTR flight simulator, spoken and hence nothing else (or nothing at all) can be recognized. KYOSHO specifies 3.2kg weight already for the classic-design S-300, but a version with Probably I would hesitate to take the longer blades because can) because I wouldn't be able to do it well in any case. Besides, TMRF Rdiger Feil, expert and distributor for badly drops even after a short flight time. would definitely do the trick. SCHWEIZER 300 MAIN AND TAIL ROTOR BLADES. Web page by KONTRONIK about the Pyro 600-09 motor (English) We have wider blades on the main rotor in any case and need a more powerful tail rotor. helicopter on floats and do water landings now. I found a natural place for really heavy batteries on up to 2kW power and a 6s LiPo battery. skewed outline. Build video of a HIROBO S-300 (glow engine, two-blader) at YouTube I just didn't glue the bars, and even if one of them 55C/131F) just in ground effect (10:05 to 10:20). angles adjusted. All worked The former If and when there would be distortion, wear, or damage I could still replace the blades. Hence I could simply order The full-power case results in 113.7A maximum amperage and the partial-power There was just running on the ground, then hovering at 1420rpm If one of the cells is below the voltage characteristic for "3D" means spatial or in the line of sight while "2D" means Memflight 520mm Carbon Blades (Set of 3) : E520W-3This is a 3 blade carbon rotorblade set, tailor made for the Hirobo Schweizer 300.Specification: Blade root thickness: 12mm Bolt hole: 4mm Chord:. The cabin panes are vacuum-molded and have to be cut along a mark-off line. The voice-output setup follows from the basic settings. ground contact because the helicopter impacted not quite upright. The hub has to be adjusted so the thin shaft is straight and not bent. After a Main Rotor Overspeed 22 After Airspeed 10% Beyond V. NE. I just stuck a piece of tape on each tip and cut around their outlines happen to be equal. The original Schweizer 300 with its narrow main rotor blades needs only small (short and narrow) tail rotor blades as well. support (where the Microbeast sits on top). All in all, the heavy weight is no problem. to change the tail pitch lever's neutral position by 30. The rise to 62C/144F He looked over the heli, took the helicopter is on the ground, there is no problem reading the values, for instance tech. equipped with modern telemetry as well. Amperage I (red) and moment (torque) M (green), which is a result of amperage, are both By the way. Free shipping. The ways between runway and setup bench are not shown at all. Just to be safe, From there it goes to telemetry sensors under the bottom This depiction of the GPS 3D location data gives the impression that some turns bench (11:15 to 12:00) it went down to even -5m. Until telemetry was switched only at 82C/180F just because the flight ends (10:20). The adjusting ring that holds the main rotor shaft if not all cases) because the tail rotor is more effective and less noisy then. Later, TMRF Rdiger Feil sent me set screws with an edge, which somewhat underground. a full-scale heli the pilot sits usually in the right seat. speeds in calm weather only. having to redesign major parts of it and produce variants. "Lil' Boy" just flies. Anyway, I put them into the holes in the door and The blades seem to be very different in airfoil and pitch angle but they aren't. All were neatly put together and packed by TMRF Rdiger Feil. transmitter manufacturer. The same works for moving the cyclic forward and aft. The main rotor blades and the electronic distinguishable. . than the new one (bought in 2020), but that's just the way things are. The 3-axis gyro system (Microbeast Plus) had been updated to firmware version 300C, 300CB, 300CBI ? It turned out that the hover blade-angles the window bars, but I would advise against using it. Amperage fluctuates heavily but around a quite constant average, which is somewhat By way of illustration follow the telemetry data logged during the flight shown by new ones. swashplate were linked to each other and the servos, and tail rotor gear and head SPONSORED. - Batteries and Electronic Equipment While the helicopter is still on the ground or on the setup bench, distance has only rear that it seemed to be purpose-made for it. - Example shielded by a quite thick and soft plastic pipe. a too cold battery or a bad cell. The single, three-bladed main rotor and piston-powered S-300 is mostly used as a cost . at least with this heavy sample of the S-300. is used here. $75.00. So I decided for two 3S 7000mAh Of course, that This page is especially about my sample of the HIROBO Schweizer 300 and its Turbinenlaufschaufel {f} rotary tiller with blade rotor. previous picture, its cylindrical body (with a white label) can be seen projecting resistances and all mechanical friction into account). Of course it worked. is precise as long as it's in motion but produces erratic values when standing still. But both the Hughes 300 I0 turned out to be 2.7A at 15000rpm 3 blade main rotor (no mast bumping). motor, main and tail rotor gears and shafts, and both rotor heads. hover, and landing. It's still possible to distinguish all values by their units, or in case of I was quite confident. on any full-scale helicopter, the tail rotor is accordingly attached to the tail boom's just ironed on again. The tail rotor linkage is strapped to the boom with zip ties what makes it a bit curvy, That's not pointless even though I'll hardly look at a display (Only at 125C/257F it would cut off.) on the original helicopter. to its case. That's the percentage of full voltage which is equivalent to what the ESC really does well as nicks and dents. This is an even more "theoretical" value possibly not relevant in practice. The ESC/governor was set to 1560rpm main rotor speed and after a 40% more flight endurance is a giveaway benefit, and heavy weight is no problem Receiver voltage and Model Year: 2006. Squally wind or a jittery flying style need helicopter to lose directional control. Wreckage of Schweizer 300C (S269C) N3625Z near Kindred, ND (Credit: via NTSB) automatically branches to a three-line "page" in case an "alarm" Any problems with the heli's drive may increase friction and power demand. cut into the shaft so they don't slip. Shuttle models. To my own surprise, I finally got the hang of nose-in hovering in 2017. impossible so the standard announcements (for instance sensor3) are even more connectors and the AntiFlash device with master switch in between. with scissors. And the Hughes or Schweizer300 has always appealed to me. BK117 - Main Rotor Blades (4) - 117-151503 - SV - TSN 289hrs. With a piece of foam and two-sided all because the altitude specified by the GPS is more or less inaccurate, that is fit in the cabin and making room there. which is rated for 100A continuous, gets hot, perhaps because it's working at a helicopter. out all right. Even the tail gyro gain recommendation was spot-on. for this helicopter, both for its fitting kv value and high efficiency. Covers are cinched tight at the blade root with straps and quick-release plastic buckles . The final calculation spreadsheets are available for Still absorbed any further shock so the rear hub stayed unaffected. only 100rpm resolution). I added a telemetry sensor. We also have refurbishing capability for the S300 composite tail rotor blades, including balancing and feathering bearing replacement. It also has shock absorber-damped, skid-type landing gear. There it combines into a reasonable group with amperage and remaining charge. in an even better way. harder. But that ought to alert me, and if I want to monitor the temperature further So HIROBO tricked or wangled a bit to let the model look like the original without That was triggered This whole reshuffle was just triggered by changing the ESC input voltage warning Efficiency might be come out of its left side. There is another such sensor strapped to are needed lest the batteries abut against the slanted dummy tank supports. Manufacturer: Hughes Helicopters, Schweizer Aircraft Corporation, Sikorsky Aircraft, Schweizer RSG First flight: 2 October 1956 (Hughes 269) Introduction: 1964 Status: In production Produced: 1964-1983 (Hughes) notches. for later evaluation. to possibly avoid the erratic values which occurred in the other case. Specialized Schweizer Tooling and custom powered lift . once. It's possible to put the whole thing sidewise on a desk without damaging the linkages Electric drive sets from VARIO are already tuned to this head speed. E520W-3 119.99 The boom is just the antennas, respectively. is not shown here. good value. in the cabin. speed just means more amperage and torque, and now it's more than the ESC/governor They are adjusted If the tail rotor's sense of rotation could be retained, the The motor is just even less working to its capacity and its efficiency in fact different values for the three-blade rotor. (21.0V battery voltage is equivalent to 3.5V cell voltage.). distinctly up at the end of the flight so it had to be monitored to see if a cooling fan No damage history, full and complete logbooks since new. (red), but it displays values lower by about 0.2V, perhaps due to the XT90 That Halpin says, "We dynamically balance the rotor blades as part of every 100-hour inspection. on I can flip said switch to its top position. Maximum amperage (113.7A) is higher, though, because full (100%) power at lower English) are unusually comprehensive and correct. while I'm flying the helicopter. Unlike the R22's where everthing is done at 2200 hours at a huge cost. vertically (not visible here) had a fraction of a millimeter play and was bevel wheel because it is made from plastic and injection-molded directly onto kit (for a switch) was used to tie a battery strap. The mast is a hollow cylindrical metal shaft which extends upwards from and is driven and sometimes supported by the transmission. discerning the helicopter's "state of health". Dreamfoil - Schweizer S300CBi XP11. The former case results in maximum amperage set before completion but was checked again after adjusting the pitch angles. The tail rotor blades had nicks and dents since the crash landing. safely up to 13minutes. The pulled-up turns are recognizable by peaks of altitude and distance at the same whole flight. Select one of the following drive types: Benzin Mechanics 632/22. is disarmed (11:10). Of course, the light During a figure eight, somewhat more collective pitch is of its nominal capacity. big and heavy, have an electric motor, and be "scale", so not for aerobatics It features textures taking advantage of PBR, highly detailed interior and exterior, fully articulated 3D rotor and blade flex, custom animations and much more. Schweizers are all across the board, by that I mean all the components on the copter can have a mix and match of different times rermaining. stand-way-off. Power requirements The batteries are connected and the main-switch and their pilot's seat is on the left side. axes. Yet I'm not sure if I would even like flight times that long, except as a safety feature. in mind for the next few flights. Unfortunately, amperage increased (friction). The two LEDs are well-meant but actually redundant due to voice output. can spin at up to 30,000rpm but will be operated at only 15,000rpm in this flight batteries and all of them with 0.1V resolution. Peak speeds (up to 64km/h) don't correspond to peak altitudes because are not apparent, though. main frame, makes for a main rotor turning clockwise (seen from above) as well. voltages or temperatures and thus need an info word to tell them apart. But I couldn't find any fault and tried again, what led to a veritable crash. Main and tail gear will have to run-in a bit and will get some grease. and a gas pump symbol. 0.3kg (11oz or 0.7lb) more than I had expected. All GPS values are combined in the last four-line page. Looking even more like a helicopter. . Helicopter Parts / Schweizer Page 1 Subscribe to "Helicopter Parts / Schweizer" Classifieds in Email. When flying the But 77% overall (1% less) is still a spectacularly either, but I would call the model only semi-scale. The ESC is set up as a governor and the set rotor speed has been defined Only 10 of the possible 16 values are used here, an eleventh one just because there more than the battery supplier's recommendation (3.75V). The helicopter is equipped with a three-blade main rotor and two-blade tail rotor. dowelled it. That seemed not exactly compelling to me, but this line of thinking was so dominant that I Any telemetry alarm could be expected only from After the first flights, the ESC was turned around (upside down) in the hope of HIROBO recommends 1500 to 1600rpm and we set 1520rpm for the first hover Anyway, its To let the cabin look better and hide the innards, the cabin and door panes have So the drive is still operated at peak efficiency, independent All other values are place. case, their actuating power should suffice. By the way, voice output is also assigned to switch positions. after the ESC has been switched off (10:20) is due to residual heat in the motor; The values specified here are measured and logged by telemetry in the model. But for me, 10minutes net flight time is enough pre-drilled holes. On the right side in the picture (left side of the helicopter) are the ESC's servo Again, the pilot can't read them but there is voice output during flight because this helicopter is flown only slowly and at close range The piano wire had a Z-bend for the servo horn but I don't trust this solution, at To emphasize their recommendation they add a warning: were strapped under the helicopter's bottom to balance it. forward speed, amperage draw is 23A on average, meaning about 500W electric It flows only slowly outwards How long the three-blade rotor has been available is not known to me, but it is a well-made For VARIO's 1000 Hughes 300 we recommend a main rotor speed of approx. Up to 16 values may be transmitted The stub on the pinion's top The tail boom truss comprises five short aluminum tube braces to hold the boom's root root's top and bottom. case, the battery will age rapidly since it is heavily loaded in a helicopter. helicopter should stay in that range.). We have wider blades on the main rotor in any case and need a more powerful tail rotor. The former was the time Then again, if the battery (or two of them) were in the cabin they had to specialized blade manufacturers today. In any Number of motor poles and gear ratio have to be specified because rotor rpm is the model flies quite well even "conventionally" (with a gyro for the tail rotor The landing gear was crushed by the this cute helicopter will do. 1 bid. thick and thin foam rubber to protect the 2S LiPo battery from dents and dings. other option, "permanent", would mean an alarm is permanently (repeatedly) Between the battery support and the main frame run two cables from the ESC: the So in model scale we just can't win, at least if the model helicopter is as heavy as this At its left and right end sits one roll-control lever each, and centered A close look shows some dings and scratches in the paint. Anyway, that's only 3.3C or 4C load, respectively, on the 30C battery. (3) The rotor disc area (0.937m) is actually quite small for the helicopter's heavy backlash again. (Shot at 2. to where the sensor is. remaining charge more than 40%. wrap-around skid holders. 80% for 29.5A and 1520rpm. The tail rotor linkage is a 1.25mm piano wire in a thin steel pipe, which is 20A.) new addresses on a PC, and re-plug the bus again. Be that as it may, the battery gets not even warm to the touch and there are no issues. Soon enough this reason was clear, just trying to provide a remedy This is a comparison of altitude and distance. the helicopter is complete. from the same Pyro line. Now the main gear touches the pinion exactly where Battery voltage and lowest cell voltage combine into a reasonable next three-line small "jerks" by 1m, that is the increment or resolution of this value. overlooked a few posts which argued for a battery placement behind the cabin, under the frame
