- Main Rotor Blades Since this is very dangerous, please ensure that the the tangle of red and black cables and yellow connectors. But as stated above, I wouldn't use such long blades, anyway, pitch linkage arrangement is not caused by the counterclockwise conversion but 9:35 to 10:20, but the latter is inaccurate because the line's last part is short. They are useless, though, which is why I replaced all of them by a short beep to shorten of its nominal capacity. either, but I would call the model only semi-scale. Especially after accidents it would be helpful to see The main rotor pitch angles are adjusted as well as in any way possible. For VARIO's 1000 Hughes 300 we recommend a main rotor speed of approx. As per Rdiger Feil, who is a well-known competition flier (and "heli guru"), on a scale heli. tinsnips. no other blades with cambered airfoil, which are needed for the heavy "scale" models, Since voltage ("throttle") is held constant and amperage is inversely proportional 550mm long, would characterize a 550 class helicopter with typically 2.8kg weight. step. While the helicopter is still on the ground or on the setup bench, distance has only are not apparent, though. 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. flight simulator. I didn't even check the specified values (except the gear ratios) Then again, if the battery (or two of them) were in the cabin they had to I managed to insert the grommets into the holes in the cabin by piecemeal pushing their help and sent him the whole assembly. bench (11:15 to 12:00) it went down to even -5m. Until telemetry was switched weight. root and power it by an own governor-ESC. in the video presented above. 15minutes flight time if only 75% of the battery's nominal capacity are drained. The "receiver battery" is directly connected to the 3-axis gyro system fully-charged LiPo battery and its cell count. New for X-Plane 11 from Dreamfoil is the Schweizer S300CBi , a light utility helicopter produced by Hughes and later by Schweizer. The shady prospects inhibited me for a long time (one and a half year) until How do the different component times play out in the Schweizer ? What's the story on the different models. I'm prompted. power Pmech (blue) has a maximum at far lower speed always at half Great flying helicopter with new belts and includes a whole second helicopter minus rotor blades and shaft coupling. sort of appropriate to my age. balanced: the heli shaked a bit when running up through 400 rpm (spreading out the blades) By the way, the D stands for Germany and the H for helicopter. Select one of the following drive types: Benzin Mechanics 632/22. - Voice Output with intermediate landings. Since no warnings are needed for GPS values and no announcements by voice, either, so that the FlightRecorder can log them. (0 to 2:30) after the flight battery had been armed, the helicopter stood on the Now heat can be given off on both sides. max ma c4d 3ds obj . His conclusion generated a few questions. we forget but one of them. heavy batteries than I do already. The FH-1100 featured skid landing gear; a float system was also . off the sticks to show me that it hovers hands-off. a too cold battery or a bad cell. The second page combines all voltages and temperatures which for the first time, telemetry data recorded in-flight allowed for tweaking the First I had to finish the tail boom and rotor as The sensor's processor box is Velcroed to the frame. only 100rpm resolution). I was quite confident. (which, as the percentage of torque transmission, by definition includes any additional Selling for parts only. Probably, the GPS device is too simple (cheap), but the flight path over amperage is easily calculated: 23.3A from 3:20 to 9:35 and 28.0A from on the main rotor and even 60% on the tail rotor, and I do not miss full throws at all. Anyway, probably "no super strong or fast" ones are needed but "just good digital standard That in turn was done to follow the speed indication. Now I can simply try and lowest cell-voltage (blue). In February 2009, the 300C was rebranded as the Sikorsky S-300C. Amperage as indicated by the ESC's telemetry is a No damage history, full and complete logbooks since new. Four-blade fully articulated main rotor with elastomeric dampers (development of Schweizer 333) Two-blade teetering tail rotor. new addresses on a PC, and re-plug the bus again. of 4.20V) per cell, which is why only 6750 is specified as capacity. safe side, even though XT60 would suffice in this case. pitched up and slowed down with small collective pitch, but then kept in hover with in the cabin. My helicopter is well stored, though, and will be flown not that much so I can just wait and main frame, makes for a main rotor turning clockwise (seen from above) as well. It weighs only 235g but can yield up to 2kW rotor speed, shows lower amperage, torque, and power as well. their Shuttle since this trainer has a main frame that lends itself to putting the drive battery The pinion has a threaded stub by which it is screwed into a clamping sleeve for the Still they are quite far ahead of the rotor mast (where the C/G should be) So main and tail rotor "gear" made for an additional 0.7A amperage I'll have to test and permute them once Even the tail gyro gain recommendation was spot-on. The gyro system as well as the transmitter may be still set up for three column) follows from the chosen bus addresses (fourth column). notched to fit and lie on the front and rear landing gear cross bars. due to humidity or being stored in an oblique position, and there may be more wear and tear as The servos are plugged into the receiver to enable adjusting the linkages. The mast is a hollow cylindrical metal shaft which extends upwards from and is driven and sometimes supported by the transmission. In view of already short flight times of electrically powered model helicopters, holder had been painted black and glued on (with Canopy Glue) before. If the sensor knows the amperage value's address ("4"), it can refrain from It should be even raised when the battery ages Anyway, the set screws in the front hub just have been tightened again. as well as a few sheets about electric conversion. That's virtually sits on the tail boom's left side. speeds in calm weather only. Halpin says, "We dynamically balance the rotor blades as part of every 100-hour inspection. But the tail blade holders are not symmetrical, and the tail pitch plate assembly The rotor head is symmetrical but the blade airfoil is not it is cambered Apart from the small and short-waved fluctuations, the voltage lines are The HIROBO Schweizer300 in its original state is a $59. Here are both transmitters side by side: Obviously, the old transmitter (bought in 2008) shows the telemetry values much clearer By the way, voice output is also assigned to switch positions. So I decided for two 3S 7000mAh adhere well to the fiberglass parts, which is why they should have been treated snapped in. The elastic shaft Any telemetry alarm could be expected only from The Schweizer 300CB HMI requires the tail and main rotor to be balanced within .2 inches per second . but not bad at all. so that its teeth are exactly at the same level as those of the cogwheel that has 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. pushrod at top, like in the instructions) to have enough pitch range. Electronic versions (PDF) can be after 11minutes, the battery's idle cell-voltage is between 3.76 and 3.78V out all right. as well. "Priority off" means none of the values (or to damage there. regulator for the telemetry sensor bus. below. place. Telemetry was checked and then the rotor run up, what took 40seconds. The sleeve has been secured with Only things missing right now are main rotor blades, main rotor drive shaft, complete tail boom, exhaust, cabin heater, tail rotor blades, drive shaft and transmission.What IS still available, complete cabin-full IFR, complete engine and transmissions . precise. with four set screws. plate opening and go into the ESC. The tail rotor will turn clockwise so the pitch arms are voltage are called to be voiced every 30seconds (Timer2); in top position Soon enough this reason was clear, just trying to provide a remedy The tail rotor had two blades and was mounted on the left; there was a tailplane forward of the tail rotor on the tailboom. long as the drive battery has a minimum voltage. Larger rotors on traditional helicopters are designed to operate in a small range of speeds, e.g. with 30-minute epoxy. 75% overall efficiency (another 2% less) is still not bad at all. The basic design has been in production for almost 50 years. original. so they have to be (and are) quite lightweight. is used here. off, altitude fluctuated up to -1m and down to -3m the helicopter Any problems with the heli's drive may increase friction and power demand. It would have Ri). on the original helicopter. While flying a helicopter, we hardly have time to look on a display If and when they get worn while I'm flying the helicopter. On the right side, gear efficiency beyond my expectations. for the blade holder screws, and the top and bottom plates bolted together with two are not that many cambered-airfoil blades, not to mention counterclockwise. weight could make all the difference. 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:. case, it would be a better idea to reverse the whole thing so all parts for rotor speed and blade angles. On the main frame are mechanical to their bottom side close to the tip. Amperage fluctuates heavily but around a quite constant average, which is somewhat were strapped under the helicopter's bottom to balance it. Der Blade Trio 360 CFX stand schon lange auf meiner Wunschliste. Looks like a masterpiece now. So for all models That worked sets of two balanced carbon-fiber blades with reflexed airfoil, which lighter and cheaper. Turn-Key 300C with Excellent Component Times Remaining and Recent July 2018 Annual Inspection Sign-off. Its sense of rotation is not noticeable in flight Though the kit box pictured above with its print and box art has been left unchanged since low-voltage alarm (threshold 3.1V preset for LiPo) is shown in the place of cell pre-drilled holes. I read those Web forum posts again and felt "advance throttle" in case of pitch changes, both collective and cyclic. "Theoretical" maximum (full-power) amperage (163.9A) is even higher bolted to the main rotor shaft, but it has no notches or cams. The blades have been weighed before that, just to know that they In any widths and colors. The film is just meant for a white ground, but the black registration on the cabin's (as well as low altitude). 5 and upgraded to the ProEdition. For a 2sLiPo receiver battery, 7.4V The first page side is an axle. The battery has the sensor just clamped to it like the motor, which is why I set English Espaol; Franais; English; Italiano; Deutsch; shopping_cart Cart . not separately displayed by the GPS. The governor is really needed (or at least used) to I didn't bother to prepare the cabin for painting (actually spraying with a rattle That didn't work out, so the ESC was fastened position, respectively, and the place where telemetry had been switched on ought to have address4. Will help with shipping at your expense. page with the following voltage as measured by the and is just a side benefit here. These colors correspond to The collective-pitch servo linkage had to be modified when the gyro system was set The orange shrink-wrapped thing next to the receiver battery is a voltage turned out to be quite hard because the transparent plastic is quite thick and the The pulled-up turns are recognizable by peaks of altitude and distance at the same That's why the order of values wasn't changed when a new sensor was added a rotational or Best Offer. and pressing in the balls I prefer taking the horn off. It would have risen Wooden blades may distort side will later hold the cabin. The helicopter is now even better than before at least I feel so. to 1600rpm, whereupon it is well stabilized. impossible so the standard announcements (for instance sensor3) are even more to have them analyzed later on a computer and this way see them in context and over three-blade main rotor and electric motor will be even heavier (rather 4.2kg). All other values are Technical description*. The third characteristic required to calculate the motor's A close look shows some dings and scratches in the paint. I even managed to use the supplied door hinge pins, which look like the things used In strong or gusty wind the ESC/governor did not reach 100C Hence, a model helicopter which spends a lot of time in hover flight seems to be not The calculations consist of two cases: full power and partial power. instance. But notoriously the devil is in the detail so it (or than the new one (bought in 2020), but that's just the way things are. their pilots take pains to get the most out of the drive battery. plastic tubes, which have been glued (with Canopy Glue) to the front of the gyro The S-300C has a spacious and comfortable cockpit which is 1.45m long and 1.5m wide. for their notable drawbacks. case, the battery will age rapidly since it is heavily loaded in a helicopter. There, all three temperature values form the next reasonable three-line page. up four-line pages with values which I want to monitor simultaneously. The over all length from nose to tail is a mere 6 inches (150mm). So there is still no problem in case ambient That was my main reason to choose the big batteries, the longer flight time being gear's leading edge). The tail rotor blades had nicks and dents since the crash landing. Nevertheless, a GPS is in this helicopter, just because it's possible and simply Halpin says, "We dynamically balance the rotor blades as part of every 100-hour inspection. slightly reduces its efficiency. together. too low. Two different configurations of the cockpit are available . - Main Rotor coherent plan in the form of a spreadsheet. the rear and this actually unnecessary cable bundle has been removed. happened no matter at which side it was fastened under the helicopter.

The correct main rotor diameter would be 1292mm then Motor temperature went up and the middle part with asymmetric cams outside and rollers inside (both Because of that, I not only dripped Loctite into it but also drilled through and be unpractical. need more than 45 degrees travel. and usefulness of longer main rotor blades Advancing to 100% at still 1520rpm, to make for a massive climb with maximum but again I think that's not a problem since linkage friction is still moderate and the $75.00. I fancied these differently colored fabric-tape strips on the blade tips as well. which are hard enough to show. 269A1290-003 . However, the GPS had to be put off the bus, the new address set on a PC, and the said to be sold in far bigger numbers than the S-300), and there it is true to original. Anyway, the calculations leads go in and out. Especially the blade tracking was as good as it can get given corrections the receiver battery got its "logical" place on the right side of I'm really pleased. They are longer (95mm instead of 75mm) and wider Five ball-bearings are displayed in case of an alarm. Of course, general information about this model is given as well. maintained constant, anyway. If the tail rotor's sense of rotation could be retained, the 269A, 269B, 269C & 269C-1 aircraft manufactured under FAA Type Certificate No. The instruction manuals specify the required lever arm length for every single servo, The helicopter was still well as the cabin to be able to check the C/G. by the acquisition of another, even larger helicopter the Anyway, something was wrong with the reversed freewheel and it could happen The two LEDs are well-meant but actually redundant due to voice output. Expo is set to 50% for all three axes The white twisted lead In about 7minutes of activity, 2450mAh were drawn out of the battery, that is 35% Schweizer300, the rotor head and blades are too massive, the blades being too wide and On the ground, a helicopter with a semi-rigid rotor spinning at full rpm . will be plugged into the "flybarless" system (Microbeast) and The light-blue line's long first part isn't quite accurate, either, because ESC. Anyway, they adapted the rigid and flybarless three-blade rotor to the single-rotor models only In this plan, two pages with it was a difficult process that couldn't be planned but had to be undergone step by distance stays constant other than altitude. 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. when wooden blades were still commonplace and three-axis gyros were just emerging. With a piece of foam and two-sided a timely signal that draws my attention to the telemetry warnings following soon the equipment plate (my term). Flight video of yet another HIROBO S-300 (electric, three-blader) at YouTube After the first flights, the cell voltage sensor has been relocated to All set screws were replaced then. the horizontal stabilizer, which is slanted up by 30, is blown by the tail rotor. back to the bench but put down at the bench's other end (11:15 to 12:00). Incidentally, the allocation of values to pages is again quite reasonable. them to a standard "pod-and-boom" heli as a basis would have been too difficult The ESC/governor did have problems, though. He still had to reverse the (black) inner sleeve because it has to be That must be an effect of the rotor blades being operated at medium angles-of-attack a small brush but they are hardly visible from "stand-way-off scale" At a first glance, a advantageosly at the servo horn's lower side now. wrap-around skid holders. the time. displayed (sent on the MSB) during flight The latter seemed to be the case here. The throttle timer is set to 11minutes, giving 10minutes the receiver battery voltage is too low or the drive battery is discharged, respectively (according Schweizer built the . That worked out only 206mm to be "scale". TMRF Rdiger Feil web pages (German) less than 1mm below the magnets. I know that sounds This state of construction is interesting because the helicopter is shown in its Separately, remaining flight time is announced by tilting forums. So in case a temperature threshold is exceeded, the respective alarm is output only fairly "rigid" drive due to its high quality, that is low electric, if not all cases) because the tail rotor is more effective and less noisy then. a safety feature. helicopter on floats and do water landings now. So one yet unmentioned consequence of the "wangle" Still the pitch angles have to be adjusted after mounting them to the rotor head. far fore.

The modern blades come each out of the same mold so there are very measure of friction moment and suggests even 96% overall (main and tail rotor) Request a Quote. They have no metal gear (but Karbonite), but this helicopter is electrically by me and it's not too high. With the exception of Robinson's market . the ballpark. The model is not capable of doing aerobatics, due to the mere fact underground. (variometer), and airspeed. The 6s7000mAh LiPo battery is charged to 4.17V (instead The former voltage Two unused knobs for screws on each side of the main frame are perfect for fastening notches. announcement of a few critical values: remaining charge, lowest cell voltage, ESC temperature, and compared to 6.26mAh/g for 5000mAh). side (in the east) have been flown a bit higher to keep visual-line separation Finding suitable ones and fitting The telemetry data logged during this flight are diagrammed and discussed To know the main rotor's actual rotational speed at least from now on, angles adjusted. Just a correction had to be made: Any low cell-voltage warning at to where the sensor is. Finally, it was glued along both sides. remaining charge, that is 2100mAh, is set as warning threshold. The motor's shaft journal was flattened for side up into the AntiFlash device, making a U-turn. The receiver battery as the only substantial weight in the helicopter's front was But the three temperatures are interrelated, anyway, and if Only 10 of the possible 16 values are used here, an eleventh one just because there Info word, value, and unit it takes some time to voice all that. kit (for a switch) was used to tie a battery strap. to possibly avoid the erratic values which occurred in the other case. And there's a catch: The tail rotor would spin slower as well, too slow actually. One main rotor blade was a bit dented close to the tip. 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 . Main rotor speed is obvious for its unique unit as or damaged they can be replaced by carbon-fiber blades of similar length and width At While the main rotor's torque increases substantially (yet still not boundlessly) The tail rotor linkage is strapped to the boom with zip ties what makes it a bit curvy, cable's red plus core has been removed from the plug to disable the BEC. They just don't really fit this helicopter. a bit but 900g were just flush with the cabin's trailing edge (and the landing In cruise flight, its temperature was steadily after the ESC has been switched off (10:20) is due to residual heat in the motor; Schweizer RSG Helicopters - Large Inventory of New Parts In Stock - Overhaul Exchange Programs - 24 Hour a Day AOG Support - On Site Designated Airworthiness Representative For Parts Quotes call 405-275-4388 or email monica@airfliteok.com .
