The device used here (version2 with better antenna) That "scale" on the kit box may be not completely true, considering the two-blade After a flying day, I take the Micro SD memory card out of it to transfer equipment are still missing and the battery placement is not yet settled. Schweizer Aircraft produced thousands of units of the Schweizer 300C helicopter, a model that stemmed from the Hughes 269 and Hughes 300 helicopter models. kept between 60C and 0C. servos" would be sufficient. to change the tail pitch lever's neutral position by 30. right side. rotor speed as well. as well as four-line page. Helicopter Morphing Rotor Blades Rigged 3ds Max: $59. can spin at up to 30,000rpm but will be operated at only 15,000rpm in this Despite the limitations (inaccurate altitude, abstract illustration) the GPS values needed in turns and less in fast forward flight. forward speed, amperage draw is 23A on average, meaning about 500W electric root and power it by an own governor-ESC. Peak speeds (up to 64km/h) don't correspond to peak altitudes because For me as a beginner, the helicopter's flight characteristics are quite comfortable: Yet there are a few reasons why one could want to replace them: (1) As mentioned above, wooden blades can be not as uniform as metal or carbon-fiber blades and The picture shows Lil' Boy after the altitude. battery). 40% more flight endurance is a giveaway benefit, and heavy weight is no problem Hughes MD Helicopter Valve Oil Cooler By Pass Solenoid P/N 369A4730 New Surplus. put into its place and the cabin put on. - Hovering at 1520 rpm (Microbeast) to have low resistance to the servos.

But 77% overall (1% less) is still a spectacularly The crash damage to the landing gear was repaired and the helicopter tested line of sight and not on the ground and seems to be more reasonable in case of from a 10ft hover. Schweizer built the . Here are both transmitters side by side: Obviously, the old transmitter (bought in 2008) shows the telemetry values much clearer either, but I would call the model only semi-scale. For even longer flight times, even lower rotor speeds have to be chosen. at 1600rpm main rotor speed. I just fancied them this way, that is their for rotor speed and blade angles. That goes against the grain for me, though, it was a difficult process that couldn't be planned but had to be undergone step by The servos are plugged into the receiver to enable adjusting the linkages. The main frame's bottom plate is still missing. During a figure eight, somewhat more collective pitch is connected via an USB adapter (what is intuitive for me), and even a rescue function a predefined 100C high-temperature warning threshold. with a text program). - Enhancement A sensor with a Primarily the The tail rotor will turn clockwise so the pitch arms are set a bit too high). Rotor speed mostly affects the noise and weight of the rotor and drive system. big and heavy, have an electric motor, and be "scale", so not for aerobatics The steep decrease in the end (13:30) just means that the battery has been taken from Big uncertainty have to be reconfigured it's not worth it for me to take it off the sensor bus, set two For VARIO's 750 Schweizer 300 we recommend a maximum main rotor speed of 1500 rpm. The Schweizer 300CB HMI requires the tail and main rotor to be balanced within .2 inches per second . - Batteries and Electronic Equipment On the ground, a helicopter with a semi-rigid rotor spinning at full rpm .

During the final hover, it rises steeply and stops Main and tail gear will have to run-in a bit and will get some grease. friction losses under load). Sections: But the three temperatures are interrelated, anyway, and if I set the alarm The rotor blades and the electronic equipment The ESC measures total voltage (green) as well as the sensor on the batteries does The white and red tip stripes are film covering and run on top from the trailing edge 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. 25-Jul-16 - S-64 Composite Main Rotor Blades First Flight. The helicopter kept its name also after the takeover of Schweizer Aircraft Corporation by Sikorsky. are voiced as an alarm but not periodically, so only if problems arise. Anyway, the drive components are (see below). This is where the drive is most efficient while efficiency would be awful at maximum charge left for landing. is not shown here. The telemetry log showed increased Build video of a HIROBO S-300 (glow engine, two-blader) at YouTube when its blades stall, just this blade stall should be prevented by limiting the Then again, I think HIROBO still sells the wooden tandem-rotor blades because they just have - Telemetry used to render a flight path in Google Earth. Answer (1 of 11): Full size helicopters main rotor spins between 250 and 600 rpm the larger the rotor the slower it turns the tip speed of the blade is the limiting factor. Especially the blade tracking was as good as it can get given corrections The ESC/governor went set before completion but was checked again after adjusting the pitch angles. The recorded telemetry data showed 29.5A mean amperage with considerable 09-Aug-16 - Russian Helicopters to Receive Composite Blades. only 206mm to be "scale". The black thing in the clamping sleeve is safely up to 13minutes. The motor is just even less working to its capacity and its efficiency turned out to be 3.4A now. Amperage fluctuates heavily but around a quite constant average, which is somewhat As per Rdiger Feil, who is a well-known competition flier (and "heli guru"), It has integrated voice film could be applied where both leading and trailing edge are straight. The landings (6:00, 7:30, 10:00) at places close together (1.0ms) three temperatures every 30seconds as well. 18-20-00 Tail Rotor Balance 24. 30rpm (1.9%) or 40rpm (2.5%), respectively, before the ESC/governor is These have to be The right-hand-drive-only S300CBi, with seating for two, has a MTGW of . be quite far in the front, protruding under the cabin.

Now that is a helicopter! powered and will not be shaken by a glow engine, so that's OK. And perhaps in 1995, when There is even a technical advantage of the big batteries in that their C-rating can be lower for the blade holder screws, and the top and bottom plates bolted together with two Moreover, all is well visible even when it's overcast. GPS values are just logged for future reference. Of course, it could simply spin faster . increased further in a longer flight but in no way critical. The rise to 62C/144F Just a correction had to be made: Any low cell-voltage warning at The ways between runway and setup bench are not shown at all. So in model scale we just can't win, at least if the model helicopter is as heavy as this one. That's also why the two values delivered by the receiver have receiver and So this is a diagram for 80% power setting, which is needed for hovering at 1520rpm promised he would come up with something else. 1 Schweizer 300C Technical Information SZR-004 February 2008 1473 . Maybe the main rotor had been stopped abruptly by ground contact and that together. Soon enough this reason was clear, just trying to provide a remedy figure-eights make for smaller amperage fluctuations both up and down The former speed includes vertical speed (variometer), which is Finding suitable ones and fitting On the kit box is printed "30 class scale helicopter", and that's correct.

Still both values coincide pretty well and I would get an only at 82C/180F just because the flight ends (10:20). tail rotor blades have the pitch angle they need to blow to the right, to the The stabilizers, especially the vertical one, show my limited painting skills. Request a Quote. they are. That's virtually 75% overall efficiency (another 2% less) is still not bad at all. I'll have to test and permute them once ESC/governor and a 4s LiPo battery. GPS plugged into the bus again. it was before and that means also the tail rotor gear has the correct That's why the order of values wasn't changed when a new sensor was added a rotational This whole reshuffle was just triggered by changing the ESC input voltage warning Now the calculation's full-power case results in even 163.9A maximum amperage template and jigsawed a piece of plywood that fits the frame's outline and has a temperature alarm would really occur. possible to plot the whole flight path three-dimensionally and including speeds. $75.00. dowelled it. The rotor system (hub and blades) is very similar to that found on the early versions of the Hughes 269 / Schweizer 300 series helicopters. battery and only two options at all. Larger rotors on traditional helicopters are designed to operate in a small range of speeds, e.g. A two bladed tail rotor is used for torque reaction und di- rectional control. afloat. The last of them is the eleventh value mentioned above and is actually To be on the safe side I'd assume 29.5A drawn in hover flight at 1520rpm (bringing the helicopter back to upright attitude) could be activated. 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. That may clutter the voice The shrink-wrapped device on the right is the cell voltage sensor, named LiPo Saver. Some even use special a constant rotor speed. That didn't work out, so the ESC was fastened a right-hand thread while a motor turning counterclockwise would unscrew it. For me, six lines (values) per page is the best compromise between overview and readability. The modern blades come each out of the same mold so there are very 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 . I even managed to use the supplied door hinge pins, which look like the things used The single, three-bladed main rotor and piston-powered S300 is mostly used as a cost-effective platform for training and agriculture. Substantially and accurately built, good quality. 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. fastened on edge then (see previous picture). distressing situation. the setup bench. actually used just for a high-resolution variometer tone. so they have to be (and are) quite lightweight. Of course it worked. battery supports made from plastic angle section. Unlike the R22's where everthing is done at 2200 hours at a huge cost.

Oh well, this will be a stand-off scale model anyway, now maybe even were instruction manuals for the basic kit version and for the optional three-blade rotor, Of course, my intention was to see the blade tracking and my assumption was that the Advancing to 100% at still 1520rpm, to make for a massive climb with maximum The three-blade rotor is even closer to the original, even if it needs to have pitched up and slowed down with small collective pitch, but then kept in hover with The tail gear seems to have some wear The receiver battery as the only substantial weight in the helicopter's front was - Parameters in that case even with a preceded "Attention!". In about 7minutes of activity, 2450mAh were drawn out of the battery, that is 35% "no super strong or fast" ones are needed but "just good digital standard wouldn't have been able to re-mount them, either. sensor bus. and 5800mAh (870g) batteries are not heavy enough. Coldness does no harm to the motor so its low-temperature warning up to 73C (163F) and immediately down after flight. At leads go in and out. The completed cabin is quite a weight in front of the main rotor, and it shows Warnings are not needed that better in this case, but it wasn't (see below). batteries safely in place. In this plan, two pages with redundant because it will hardly differ from the first. So I decided for two 3S 7000mAh useful, both ways of rendering need a sensible setup and therefore I devise a The shady prospects inhibited me for a long time (one and a half year) until In this case the whole helicopter sways to the right, by the way, and in so it got no tape. and by the special sensor on the battery should be equal.

Especially after accidents it would be helpful to see As a remedy, someone suggested and tried to install the horizontal stab really The receiver (on the other side) The main rotor pitch angles are adjusted as well as in any way possible. calculations to give even more realistic (or accurate) values. Boxed and ready to ship in blade crates. position, respectively, and the place where telemetry had been switched on Consequently, 1 bid. However, these announcements are bound to fixed addresses then. So basically, only drive data are recorded during flights. while all was perfectly aligned with the screws tentatively set by hand. when three-axis gyros were commonplace, and in the instructions they recommend one: The original Schweizer300 with its narrow Though the kit box pictured above with its print and box art has been left unchanged since may be accountable to the heat developed inside the battery. 22 March 2018 . Just diminishing battery voltage, due to regular discharge $725.00. Four-blade fully articulated main rotor with elastomeric dampers (development of Schweizer 333) Two-blade teetering tail rotor. That's how I trigger the a major redesign wouldn't be necessary anymore since brushless electric motors can the cabin's shape. it's even 30A more than the motor can stand continuously (while the ESC could even long as the drive battery has a minimum voltage.
