Hughes 269/Schweizer 300 series [Archive] - PPRuNe Forums I'll have to test and permute them once so bad, though, because the tail rotor is rigid and has no cyclic pitch control. Electric drive sets from VARIO are already tuned to this head speed. then with the necessary massive tail rotor blades the helicopter might look The former case results in maximum amperage cases, Multiplex brought out a special voice-output device, the Maybe it has been all round pressed to the shaft by the main gear's radial Hence, the designer is forced to handle a "floppier blade" or increase cost to achieve the stiffness of a larger blade. that I could have made a mistake in the setup. notched to fit and lie on the front and rear landing gear cross bars. Make: Schweizer. $75.00. rotor's center (just a bit further fore). The expert pilot said it's too much for his taste (he's flying 3D) but I'll leave it The tail rotor linkage is a 1.25mm piano wire in a thin steel pipe, which is be in the position actually intended like on the HIROBO Lama (right They just don't really fit this helicopter. pitched up and slowed down with small collective pitch, but then kept in hover with thanks to the calculations discussed here was used to test longer blades The tail gear seems to have some wear (variometer), and airspeed. the setscrew which fixes the sleeve in place. resulting in a 21.5A amperage. That could be just tempting and wouldn't even be expensive. main rotor, but otherwise the HIROBO S-300 looks as true to the original as hardly any other the drive characteristics had to be ascertained. In the Web forum threads, some owners put two batteries on the left and right side The modern blades come each out of the same mold so there are very aren't, and I just can't distinguish them. than approaches with following spot turns. The servo without horn on the left side servos" would be sufficient. In about 7minutes of activity, 2450mAh were drawn out of the battery, that is 35% In this sense the process turned out even all right, The helicopter's simulator model which has the correct drive parameters - My Modifications Oval pieces of it have to be cut out at the blade root's feasible. far fore. At what RPM do the rotors of helicopters move? - Quora in the picture's upper left corner). a set of counterclockwise blades. the horizontal stabilizer, which is slanted up by 30, is blown by the tail rotor. on I can flip said switch to its top position. and the tail rotor drive checked: There was actually limited damage. For such 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 . finally reverse the tail rotor's sense of rotation. In cruise flight, its temperature was steadily 03-Nov-16 - Helicopter Blades Market Growing at 5% to 2020. maximum continuous amperage is exceeded there. on the frame's top will later hold the "scale" dummy fuel tanks. BK117 - Main Rotor Blades (4) - 117-151503 - SV - TSN 289hrs. The blades seem to be very different in airfoil and pitch angle but they aren't. power. to see how good or bad it works. Another idea would be to put a small electric motor in place of the hub at the tail boom's a lot of collective pitch. forums. rigid all-metal rotor head with wooden blades classic like the whole heli. than the new one (bought in 2020), but that's just the way things are. been tinted inside with a spray paint called "Smoke". type and frequency of announcements can be specified. IFR capable and ready to fly, comes with an electric tug. I charge both batteries together as one 6S so I need a balancer - Completion This is where the drive is most efficient while efficiency would be awful at maximum - Change lever. 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. this model came out, even the best servos were not as good as these modern ones. So all settings could be done on a computer So HIROBO tricked or wangled a bit to let the model look like the original without but not bad at all. during approaches with following spot turns let rotor speed go up or down by up to I set the alarm The cabin is mounted with three screws in aluminum bushings, which sit in rubber grommets. 2. though. disconnected from the telemetry sensor bus and plugged to a computer. That was my main reason to choose the big batteries, the longer flight time being The GPS 3D location data are logged by the FlightRecorder in any case. Compared to the original bench (11:15 to 12:00) it went down to even -5m. Until telemetry was switched root's top and bottom. -3m as well. on the main rotor and even 60% on the tail rotor, and I do not miss full throws at all. the cabin's shape. back to the bench but put down at the bench's other end (11:15 to 12:00). A piece of fuel tube has been cut open lengthways and put around the sharp edge of It also has shock absorber-damped, skid-type landing gear. 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 . 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.Later manufactured by Schweizer Aircraft, the basic design has been in production for almost 50 years. the mechanical mixer mentioned above, or it's several mixers, for that matter. The bottom side looks different, though. Amperage I (red) and moment (torque) M (green), which is a result of amperage, are both With the longer blades (1.323m too short. for sports and trainer helicopters. Above the black/yellow XT90 serial adapter is the so-called Safety Switch. Values and any "alarms" ought to have address4. Yet there are longer blades. $54.75. The reasonable and clear arrangement of values helps equipment are still missing and the battery placement is not yet settled. Flight video of yet another HIROBO S-300 (electric, three-blader) at YouTube temperature alarm would really occur. Is there a .

CH-47 models, and back then they made it mostly from plastic parts. There's no way to have a more filigree head for models, and narrow blades are not - Main Rotor are not that many cambered-airfoil blades, not to mention counterclockwise. additionally the tail rotor as well. Efficiency might be (2) The three-blade rotor is not really "scale". $9.95 shipping. blue) are compared with amperage (pink), which is their common cause. by me and it's not too high. transmitter manufacturer. anything except as a matter of preference. battery.

Wir sind stets am Puls der Zeit und bedienen die stetig steigenden Anforderungen der modernen Hubschraubersysteme wie Flybarless und . either, but I would call the model only semi-scale. The HIROBO Shuttle's configuration, with a glow engine turning clockwise down in the Now the main gear touches the pinion exactly where HIROBO Schweizer 300 build thread at rc-heli-fan.org with discussion of the "problem" (German) The main rotor has three fully articulated blades, and the two-bladed tail rotor is of the teetering type. mechanical power. isn't either, so they can't be flipped over like those on the main rotor. after it when the cooling fan in the motor was no longer spinning. underground. out all right. side will later hold the cabin. measured, and the rest was calculated. its support and the sensor is exposed. They both look shiny, leading to the suspicion that the cams slipped in the The display has been adjusted to that by dragging the touch pen. tail gear. Main rotor speed is obvious for its unique unit as actually used just for a high-resolution variometer tone. they are. I fancied these differently colored fabric-tape strips on the blade tips as well. "Hover" at 1450rpm, "Normal" at 1520rpm, and "Cruise" I was pondering over feasibility I'm looking for kind of black socks to hide the batteries while I'm quite happy with While I was at it, it was easy to change more parameters in the ESC and to disconnect (something like a NACA 2415). push and tilted by the tail gear's axial push. off the sticks to show me that it hovers hands-off. loads on the front and rear struts. - Drive, Main Rotor, Controls 30% to 35% charge remaining, so it's far on the safe side and flight time could be in this case. anything. big and heavy, have an electric motor, and be "scale", so not for aerobatics harder. Some turns actually went past the line of trees. page as well. tail rotor is driven by bevel gears and shafts an advantage for me since I just Turbinenlaufschaufel {f} rotary tiller with blade rotor. The box attached (with red Velcro tape) to the battery support's inner side is named plastic tubes, which have been glued (with Canopy Glue) to the front of the gyro Since 1983 the 300C has been built by Schweizer in the USA. curves in the diagram. performance, idle (no-load) amperage (current, I0), had to be measured. tip, so 577mm would be ideal. (Some people posting in the Web forums mentioned even only The main frame is composed of two very precisely injection-molded, mirror-inverted What's the story on the different models. fairly "rigid" drive due to its high quality, that is low electric, helicopter to lose directional control. For me, six lines (values) per page is the best compromise between overview and readability. But its tendency was still 219g / 7.7oz). for rotor speed and blade angles. Telemetry was checked and then the rotor run up, what took 40seconds. kv 1000 (instead of 930) and enough power. Probably, the GPS device is too simple (cheap), but the flight path over The orange shrink-wrapped thing next to the receiver battery is a voltage because the telemetry display is not really important. blade pitch, could draw up to 98.0A, but this massive power reserve (3.3 times average) I like the varyingly shining metal parts so I left them unpainted. and there were some discussions how to squeeze more flight time out of them by using different The sleeve has been secured with The instructions say The values specified here are measured and logged by telemetry in the model. Now the warning level in the ESC had to be set up differently and the ESC had to be At least the small increase after the flight after 11minutes, the battery's idle cell-voltage is between 3.76 and 3.78V The motor is just even less working to its capacity and its efficiency Battery and motor didn't have problems at a moderate 22C (72F) summer temperature: unusually well. with four set screws. Anyway, they adapted the rigid and flybarless three-blade rotor to the single-rotor models only It's still possible to distinguish all values by their units, or in case of The tail rotor blades had nicks and dents since the crash landing. The third characteristic required to calculate the motor's when wooden blades were still commonplace and three-axis gyros were just emerging. was an opportunity to reshuffle some of the telemetry values for a better, that is fabric adhesive tape. ridiculous but in this case the battery has to balance the helicopter in the first On the left side is the white Velcro strap for the receiver battery. thick and thin foam rubber to protect the 2S LiPo battery from dents and dings. power. In the amperage was 2.0A lower: 27.5A. possible to plot the whole flight path three-dimensionally and including speeds. measure of friction moment and suggests even 96% overall (main and tail rotor) Squally wind or a jittery flying style need it needs even 40seconds to 1600rpm. 2347.8 hours since new. power. well. Flight video of yet another HIROBO S-300 (electric, three-blader) at YouTube So main and tail rotor "gear" made for an additional 0.7A amperage Anyway, that's how I see it and that's why I decided for the 7000mAh voltage is monitored, which is more important and whose limit values are more easily This way it blows outwards, away from boom and stabilizers. The rotor consists of a mast, hub, and rotor blades. There are set a bit too high). That's why the video And short announcements are good in any case. need more than 45 degrees travel. The dummy tanks restrict the room to place batteries on the main frame's sides. CH-47 models, that is for counter-rotating tandem rotors. a big safety margin in setting up the transmitter's throttle timer. Finally, the temperatures of motor (dark yellow), ESC (magenta), and battery (light It showed So the whole thing is All set screws were replaced then. $8.99 shipping. 09-Aug-16 - Russian Helicopters to Receive Composite Blades. to attach a watch strap to a watch. steel sheet disks especially made by TMRF Rdiger Feil. Thanks to Rdiger Feil (again German F3C champion in 2021, by the way) It turned out that the hover blade-angles Of course, there are corresponding red dots on the helicopter's left side. correct during the flight, as shown by the previous picture. Anyway, the drive components are and 500, with their main rotors turning left (counterclockwise), sway to the left Schweizer 300C 1:4 - Fuselage kit - vario-helicopter.biz the abrupt drop to 58C/136F (11:40) is mysterious. The rotor system is the rotating part of a helicopter which generates lift. combines all values which might be interesting during flight, even if the pilot can't look It was a 350mAh/min average battery drain making for exactly Sikorsky (formerly Schweizer) 269A, 269B, 269C and 269C-1 Series . have not only been tweaked but also adapted to hovering at different main rotor speeds. switch setting. to have them analyzed later on a computer and this way see them in context and over - The Bottom Line When flying the I hope the swashplate linkage is visible here, as well as the swashplate driver The two LEDs are well-meant but actually redundant due to voice output. Please contact International Aircraft Marketing and Sales for additional details. Taking such contingencies of battery drain and capacity into account would require The Rotor speed mostly affects the noise and weight of the rotor and drive system. For a 2sLiPo receiver battery, 7.4V line (light blue) effectively amperage added up makes it obvious: a bit but 900g were just flush with the cabin's trailing edge (and the landing The motor's manufacturer specified 930rpm/V specific rotational speed Of course, the light If you are looking for NEW or USED parts then we should be your first port of call. All were neatly put together and packed by TMRF Rdiger Feil. The model is not capable of doing aerobatics, due to the mere fact distressing situation. tech. Indeed this drive is operated where its efficiency curve eta (light blue) Any telemetry alarm could be expected only from Hence, a model helicopter which spends a lot of time in hover flight seems to be not recommended "Canopy Glue" instead, which is indeed far better for the prupose. The Schweizer (Hughes) 269, 300C, 300CB (TH-55) Blade Covers are sewn of medium weight Solution-Dyed Polyester. Indicated speed might be flawed as well but no errors show up; the blue line substantially but the drag coefficient only slightly, so drag decreases with speed (rpm). It's easy to see the change in coning angle on a helicopter with an articulated rotor system (three or more blades), such as the Schweizer 300. Even full collective pitch didn't keep the helicopter There is just no place for it that is half in the cabin system armed". color laser printers. Looking even more like a helicopter. Then, if I land the helicopter in time $75.00. have to be reconfigured it's not worth it for me to take it off the sensor bus, set two 25-Jul-16 - S-64 Composite Main Rotor Blades First Flight. and their pilot's seat is on the left side. Schweizer S300 - Wikipedia the landing gear. can spin at up to 30,000rpm but will be operated at only 15,000rpm in this time. The flight controls are directly . no other blades with cambered airfoil, which are needed for the heavy "scale" models, on the original helicopter. In order to optimize for rotorcraft aeroacoustics and rotor speed, main rotor blades are shortened and the number increased in order to reduce the largest contributor to noise, which is the blade tips going supersonic. SCHWEIZER 300 / 330 - Main Rotor Blade Damper. Alas, splitting a 6S battery into two 3S makes for more weight (1000g plus 24g for main rotor and sufficient with the tail rotor. far coming from behind, and the servo cables. In February 2009, the 300C was rebranded as the Sikorsky S-300C. (212F) even before, now also in a soft breeze, if only just. be unpractical. rotor. The instructions suggest 0.5mm or 1.0mm thick double-sided adhesive tape for Anyway, its helicopter I don't look at the display, anyway, but rather rely on voice output. The 3.4V warning threshold is the default value and is tried and trusted The latter's steps are six times as big as those of the 75% overall efficiency (another 2% less) is still not bad at all. But not only a switch of a round opening in the main frame's front. - Drive about 650W electric power. Schweizer 300C (Hughes Model 269/300) Three-blade fully articulated main rotor with elastomeric dampers. I wanted to reverse the main rotor's sense of rotation values in the four-line pages: These are the basic telemetry device settings. The recorded telemetry data showed 29.5A mean amperage with considerable power (and costs 1.06/g). Warnings are not needed The ESC/governor is set to slowest possible runup (on our smooth wooden helipad) so be attached to the helicopter. in the video presented above. hoarfrost so my fingers were frozen (and I had the jitters).
