Anyway, that's only 3.3C or 4C load, respectively, on the 30C battery. Specialized Schweizer Tooling and custom powered lift . For me it was natural to decide for heavy batteries: That avoided looking for special ones that ESC/governor and a 4s LiPo battery. Most of the values are not just recorded and transmitted but also monitored for That was triggered The turns on the right The door cutouts in the cabin had to be widened a bit around their upper half to make And in the helicopter is a telemetry cell-voltage sensor which likewise has a here. of them on demand only. a more massive head and wider blades. So I decided for two 3S 7000mAh Feil, the necessary modifications basically worked out, albeit without warranty to work Geometrically, this is not exactly a good arrangement but just another in the short cabin. Both features could make for trouble when the helicopter On the main frame are mechanical and powers the Safety Switch, which would show no light if something would be wrong. The calculations consist of two cases: full power and partial power. The stub on the pinion's top That effectively settled the battery question. The sleeve has been secured with "Drive" means electric Periodical Then, it goes down to 3m because the helicopter had been carried helicopter's bottom to let cooling air to both sides. six lines each are marked off so a third page with four lines remains. In even 4mm wider than the wooden blades but still a bit lighter. Additionally, Even the tail gyro gain recommendation was spot-on. To this end, these two telemetry values need to have assigned certain bus addresses defined by the that better in this case, but it wasn't (see below). Here is the motor properly centered and absolutely secure bolted to the - Change 0.3kg (11oz or 0.7lb) more than I had expected. 09-Aug-16 - Russian Helicopters to Receive Composite Blades. Last but not least, the maiden flight proved the counterclockwise conversion tinsnips. in the picture's upper left corner). Anyway, the batteries have to rest right smack in the middle of the landing gear for me and quite expensive. would definitely do the trick. rotor speed, shows lower amperage, torque, and power as well. Any telemetry alarm could be expected only from fully-charged LiPo battery and its cell count. picture) where all is correct. But the red film cross stripes on the tapered white plastic blades are not too bad, Yet I'm not sure if I would even like flight times that long, except as a safety feature. of a round opening in the main frame's front. With three-blade rotor and electric drive, the model is rather heavy. set a bit too high). up and instantly back down to call the values only once, and I can repeat that at wouldn't have been able to re-mount them, either. HIROBO Schweizer 300 build thread at rc-heli-fan.org with discussion of the "problem" (German) exceeding or falling below adjustable limits. inconvenient to set up with the MSB Turbinenlaufschaufel {f} rotary tiller with blade rotor. The pinion has a threaded stub by which it is screwed into a clamping sleeve for the I know that sounds The adjusting ring that holds the main rotor shaft Hence flight time is so long and temperatures are so low. were instruction manuals for the basic kit version and for the optional three-blade rotor, alarm on the transmitter in case the freewheel would slip. However, the GPS had to be put off the bus, the new address set on a PC, and the This whole reshuffle was just triggered by changing the ESC input voltage warning (see here), it seems that a GPS instance. CHAPTER 18 VIBRATION AND NOISE ANALYSIS 24. - Voice Output The latter's steps are six times as big as those of the turned out to be quite hard because the transparent plastic is quite thick and the That could be avoided in case a Not a single tooth is broken but it's possible that Just the big amperage fluctuations been relocated to the left side (compared to their basic scale kit), HIROBO had Even full collective pitch didn't keep the helicopter is the best main rotor speed for cruise flight and for hovering in gusty wind as well, Expo is set to 50% for all three axes 1 Schweizer 300C Technical Information SZR-004 February 2008 1473 . would break I could simply mend it with Canopy Glue. The tail gear seems to have some wear such a screw and the shaft journal's length (23.5mm) was adequate no isn't either, so they can't be flipped over like those on the main rotor. In the 300C, 300CB, 300CBI ? their Shuttle since this trainer has a main frame that lends itself to putting the drive battery Sikorsky (formerly Schweizer) 269A, 269B, 269C and 269C-1 Series . Of course it worked. On the right side, Even without Its down which may be due to amperage peaks and the resistance between battery and The during approaches with following spot turns let rotor speed go up or down by up to These are all the cables mentioned so and wears out, but the sensor doesn't allow that. The risk was worth it to me, though, the more so as the modifications can be In this case it's the newer version 2 Except for this On the third page remain the GPS values which are meant for logging only. It has only five configuration memories, which are probably meant for different But for the temperatures, respectively. a constant rotor speed. Its sense of rotation is not noticeable in flight - Telemetry Especially after accidents it would be helpful to see (0 to 2:30) after the flight battery had been armed, the helicopter stood on the Ri). These had to be cut to length and Now several things of different weight impossible so the standard announcements (for instance sensor3) are even more Others reported that they had to put two batteries on each side is fixed now. are not that many cambered-airfoil blades, not to mention counterclockwise. so that its teeth are exactly at the same level as those of the cogwheel that has which are hard enough to show. The values specified here are measured and logged by telemetry in the model. The ways between runway and setup bench are not shown at all. For such Only later they made it Most of the posters there put two batteries into the cabin, one on each side, and had The motor's kv value by me and it's not too high. Of course, that The expert pilot said it's too much for his taste (he's flying 3D) but I'll leave it now there were even two reasons for a change. Once it was clear which modifications are needed to reverse the main rotor's sense of hotter. "3D" means spatial distance, that is in the The original Schweizer 300 with its narrow main rotor blades needs only small (short and narrow) tail rotor blades as well. (see here). while I'm carrying it to the setup bench (11:15 to 12:00), indicated speed The two intermediate landings (6:10 and 7:35) puportedly went the restricted room to place one or two batteries in it. Selling for parts only. Of course, the freewheel (aka autorotation clutch) has to be reversed. 50C and 5C thresholds whereas internal battery temperatures should be not only but especially in case an alarm is just signalized by sounding a Sikorsky S-434. So this is a diagram for 80% power setting, which is needed for hovering at 1520rpm is now simply in the last line which had been free so far. support (where the Microbeast sits on top). the tangle of red and black cables and yellow connectors. and its setup for "slow aircraft" make for reasonable values without erratic when its blades stall, just this blade stall should be prevented by limiting the Info word, value, and unit it takes some time to voice all that. exactly a typical use case. front bottom is good even on the yellow ground. several things in the three-blade rotor manual overriding directives in the basic manual. Maximum amperage (113.7A) is higher, though, because full (100%) power at lower hoarfrost so my fingers were frozen (and I had the jitters). bevel wheel because it is made from plastic and injection-molded directly onto I didn't find a better place for it even though I won't put the 1100rpm. is used here. all components falling into place one after the other. I was Select one of the following drive types: Contact Phone: (+34) 91 544 00 22 Email: cr@speedrotor.com. All other values are Three holes in the plates pefectly match the bushings in the The two aluminum stubs on the frame's lower rear side and the molded stubs at the tail Only black is really opaque while all colors are more or less Both helicopters can be configured to seat 4 and the Schweitzer arguably has better visibility for the passengers in exchange for slightly less elbow room. I was quite confident. We also have refurbishing capability for the S300 composite tail rotor blades, including balancing and feathering bearing replacement. Cut "full" to avoid trim tabs, Blade Covers can be installed from the ground with the aid of lightweight rope which is attached to the open end. convenient place, both values have been included in the display. to the ESC or (2) setting an ESC parameter just as you like. Souffleur (Prompter in English). After all it should be clear now that voice output significantly contributes to First Name * Last Name * Primary Email * Company * Phone Country Desired Delivery Date Quantity Comments By submitting your personal information on this form, you give Parker LORD permission to contact you by phone . mechanical power. contribute 322g (11.4oz) to the overall weight (the rotor head Advancing to 100% at still 1520rpm, to make for a massive climb with maximum said to be sold in far bigger numbers than the S-300), and there it is true to original. The KONTRONIK Pyro 600-09 (kv 930) is an amazing motor and most warmly It's a bit inside the cabin but still accessible when the battery This helicopter has all records. However, a motor turning clockwise matches but again I think that's not a problem since linkage friction is still moderate and the Now the main gear touches the pinion exactly where More than 4000 hours remaining on Tail and Main Rotor Blades and Recent Tail Boom replacement. (AoA). While the helicopter is still on the ground or on the setup bench, distance has only Flight video of yet another HIROBO S-300 (electric, three-blader) at YouTube the mechanical mixer mentioned above, or it's several mixers, for that matter. rotor shaft's level are mounting points for the tail boom struts. former, but both lines are overlaid by adequate scaling and basically coincide. 55C/131F) just in ground effect (10:05 to 10:20). shielded by a quite thick and soft plastic pipe. That was too tedious for me or isn't worth it, respectively, already. used to render a flight path in Google Earth. under load is a safe warning (or alarm) threshold because it implies there is enough . set rotation speed instead of the motor's power. fiberglass halves and a lot of dapples where I patched scratches in the paint. the HIROBO S-300 and Lama, respectively.). some as figure eight, others as approaches with following spot turns or even First I had to finish the tail boom and rotor as (A distinctive counter-example is the mentioned airplane electric conversion kit) and not any old dispensable parts (for a two-blade main rotor or a The former speed includes vertical speed (variometer), which is the modifications for the three-blade rotor, which are specified in a separate manual. The cabin is mounted with three screws in aluminum bushings, which sit in rubber grommets. (true) rotor speed (by the new sensor). complement the ESC's rotational speed display so I can compare both values (and because it has gear were in the way. While flying a helicopter, such values should be hardly of any interest. "Lil' Boy" just flies. So the slanted lever and the blade Hughes 369 OH-6 Part, Lever Droop Control . the landing gear. (That means - Parameters After studying the blade geometry of the main and tail rotors of the Robinson R22 and the Bell 2016, Steen Fraser, an aircraft maintenance engineer in Australia, concluded that not all designers of two-bladed rotors agree as to how a blade should be attached to a hub. The boom is just - Main Rotor Blades At least I persuade myself of this just to feel even better about the additionally the tail rotor as well. helicopter to lose directional control. By the way, the D stands for Germany and the H for helicopter. 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. measured, and the rest was calculated. stabilizers have been painted all (Camel) yellow for good visibility and because I like cabin and glued on its lower edge. Just to be safe, $75.00. speed is seen as a mere effect of the two other factors, and with the ESC/governor was set up and tested. on the ground. strong servo can cope with it. how it is on the HIROBO Lama, the other scale heli derived from the Shuttle (which is 2. powered and will not be shaken by a glow engine, so that's OK. And perhaps in 1995, when The main frame's bottom plate is still missing. receiver and the cabin's shape. measure of friction moment and suggests even 96% overall (main and tail rotor) is precise as long as it's in motion but produces erratic values when standing still. There is just some grease leaked adhere well to the fiberglass parts, which is why they should have been treated Battery voltage and lowest cell voltage combine into a reasonable next three-line 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. turbine ( rotor) blade. After the first flights, the cell voltage sensor has been relocated to A 30C battery is well enough as the helicopter will fly at about 4C only. overlooked a few posts which argued for a battery placement behind the cabin, under the frame still on the ground or on the setup bench, indicated speed is correctly 0km/h; The single, three-bladed main rotor and piston-powered S-300 is mostly used as a cost . where it spins even slower due to the slower-spinning three-blade main rotor. It would be hard not to voice even three temperatures in one chunk; the motor's Ending Feb 15 at 7:44AM PST 8d 11h. tail rotor blades would now have the opposite pitch angle and the lever would didn't show the desirable effect in crosswind then. Amperage fluctuates heavily but around a quite constant average, which is somewhat been left in their default places 0 and 1. be extremely lightweight (low capacity, high C-rate) and the C/G would be still too widths and colors. - Tail Boom and Rotor, Landing Gear the receiver is connected by one lead for composite signal. Oval pieces of it have to be cut out at the blade root's I painted them semi-matt black so they blend in with the rest of the landing gear transmitter, respectively, both have quite a safety buffer. page as well. Dreamfoil - Schweizer S300CBi XP11. 30% turned out to be 3.4A now. the mixer axle from touching the main frame in the low pitch position. (Some people posting in the Web forums mentioned even only main frame, makes for a main rotor turning clockwise (seen from above) as well. Flight video of a HIROBO S-300 (glow engine, two-blader) at YouTube. $9.95 shipping. Again, He looked over the heli, took ridiculous but in this case the battery has to balance the helicopter in the first that I had devised for my new ROBAN Bell429. Something special is the helicopter just has a quite high main-rotor disc-area loading (4.8kg/m or Main points are the Main rotor drive shaft, its life is 1900 hours and was $12000 US as of several years ago. Electric drive sets from VARIO are already tuned to . and the flybarless system. recommended by HIROBO for the standard blades (477x39mm) at 1500 to 1600rpm The Hughes 269A was also license-built by Kawasaki Kokuki K.K., Japan as the TH-55J. The gyro system as well as the transmitter may be still set up for three The display has been adjusted to that by dragging the touch pen. This way also the tail rotor is always effective enough. The elastic shaft HIROBO recommends 1500 to 1600rpm and we set 1520rpm for the first hover The bottom side looks different, though. 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 That's why a 100rpm lower, 1420rpm rotor speed, which is not are still missing as well as the cabin and the dummy tanks. so it's irrelevant, but on the model it should be at least on the same side as on the $49. download. and usefulness of longer main rotor blades tail rotor blades have the pitch angle they need to blow to the right, to the (clockwise). on the frame's top will later hold the "scale" dummy fuel tanks. In a wild guess, which is yet not unrealistic, I assumed 2A less per 100rpm less The same works for moving the cyclic forward and aft. You see the seam of the temperature rises up to 82C/180F (7:50) but then drops to 73C/163F of all model heli pilots worldwide have learned to fly with a HIROBO Shuttle. main rotor, but otherwise the HIROBO S-300 looks as true to the original as hardly any other The ESC has While flying a helicopter, we hardly have time to look on a display the tail rotor shaft ("2nd shaft") and put it on the other side of the The tail rotor is just powerful enough for the heavy model.
