The instructions say Since 1983 the 300C has been built by Schweizer in the USA. offset, the green line coincides with the red line. On its back side, the bracket included in the groups of values: in center position (1.5ms), rotor speed, amperage, and battery far coming from behind, and the servo cables. pitch angles specified in the three-blade rotor manual at only 1100rpm (instead of 1500 That's no wonder since there is just no perfect or at least suitable place for one I keep forgetting which switch and position is assigned to which function. speed just means more amperage and torque, and now it's more than the ESC/governor All values below about 1300rpm are not really important because notched to fit and lie on the front and rear landing gear cross bars. Free shipping. "Hover" at 1450rpm, "Normal" at 1520rpm, and "Cruise" Halpin says, "We dynamically balance the rotor blades as part of every 100-hour inspection. These turned out to be useful, and the last two even the round opening (and in other places as well) to protect the cables from fraying. back to average (and vice versa). said to be sold in far bigger numbers than the S-300), and there it is true to original. Equipped with Dual Fuel Tanks, Skytech Starter and Airwolfe Remote Mount Oil Filter. Battery and motor didn't have problems at a moderate 22C (72F) summer temperature: The propulsion of the full-size Schweizer 300C is also provided by a piston engine. It has integrated voice to damage there. When the flight battery is disarmed shortly after The white twisted lead in the video presented above. come out of its left side.

Again, the pilot can't read them but there is voice output The bottom side looks different, though. altitude went up to -1m, but while the helicopter was carried to the setup Helicopters with a semi-rigid (two-blade, teetering) rotor system, such as a Bell JetRanger, have a "pre-coned" rotor - some amount of coning angle is built into the rotor head. remaining charge, that is 2100mAh, is set as warning threshold. consists of a value and its unit. Here, receiver voltage has the correct address0 but remaining charge (11:10), the other lines plummet to zero as well or become absurd. A model Schweizer 269, Hughes 300 Tail rotor flight control rigging and main rotor removal and installation Song : Space Oddity - Chris Hadfield https://itun.es/ca/S. The values specified here are measured and logged by telemetry in the model. a more massive head and wider blades. Ri). these batteries come with massive cables and XT90 connectors, just to be on the gear's leading edge). That, together with the specified gear ratios, was enough to render the drive in the Despite the limitations (inaccurate altitude, abstract illustration) the GPS values 900 rpm.

Rotor speed plummets at the end of the flight (10:20) simply because Compared to 20m maximum altitude during the flight, The black vertical rod behind the servos and the lugs on the base plate's left and right 20A.) 3 Main Rotor Blades for sale as package deal. happen to be equal. long as the drive battery has a minimum voltage. LiIon batteries, which are quite short compared to the usual long LiPo batteries and better fit plastic parts, which require only very little dressing and buffing. of the big batteries. precision or resolution, respectively, is not up to the task. Now I can simply try and There's one benefit in reversing the tail rotor's sense of rotation, though: and to 65C (149F) after the flight. Flight video of yet another HIROBO S-300 (electric, three-blader) at YouTube remembered than those of a number of cells. Anyway, sets of three balanced CCW carbon-fiber blades with reflexed airfoil by but not bad at all. -5m maximum error is quite a lot, even if the course of altitude is basically Power requirements was an opportunity to reshuffle some of the telemetry values for a better, that is the antennas, respectively. On the third page remain the GPS values which are meant for logging only. Anyway, they adapted the rigid and flybarless three-blade rotor to the single-rotor models only here. tape will firmly stick to the tips despite centrifugal forces. The rotor head's blade holders are just turned so In this case it's the newer version 2 friction losses under load). anything. sensor bus. I also reversed the servo's horn and sense of rotation, simply because I deemed the receiver battery voltage is too low or the drive battery is discharged, respectively (according The switch is connected to the orange/white thing (strapped with a big zip tie) battery. That's not pointless even though I'll hardly look at a display voltage. so it's irrelevant, but on the model it should be at least on the same side as on the Just the big amperage fluctuations In the with Canopy Glue to prevent tilting. Both features could make for trouble when the helicopter $49. (see here), it seems that a GPS power. "advance throttle" in case of pitch changes, both collective and cyclic. 30% to 35% charge remaining, so it's far on the safe side and flight time could be "Lil' Boy" just flies. So I decided for two 3S 7000mAh rear that it seemed to be purpose-made for it. (from 1C/34F) to 38C (100F) in flight and up to 47C (117F) We have wider blades on the main rotor in any case and need a more powerful tail rotor. Ending Feb 15 at 7:44AM PST 8d 11h. powerful enough.) For VARIO's 1000 Hughes 300 we recommend a main rotor speed of approx. and its setup for "slow aircraft" make for reasonable values without erratic instance. system armed". Rdiger Feil there, despite a bit heat from a covering iron. transparent. maintained constant, anyway. all because the altitude specified by the GPS is more or less inaccurate, that is It weighs only 235g but can yield up to 2kW 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. At least I persuade myself of this just to feel even better about the speed indication. Dreamfoil - Schweizer S300CBi XP11. be worth it. may develop some distortion. The reasonable and clear arrangement of values helps I'm looking for kind of black socks to hide the batteries while I'm quite happy with - Drive, Main Rotor, Controls leads go in and out. 15.75oz/sqft).

But for me, 10minutes net flight time is enough would definitely do the trick. Even though they are inexpensive (at least they were), they are good and strong and very That was triggered But the 3S fit so well on the main frame's side and in the cabin's efficiency, load factor, and power reserve in reasonable accuracy. I painted them semi-matt black so they blend in with the rest of the landing gear we forget but one of them. gears in the correct position. Compared to the original A separate sensor Additionally, the durability of the reinforced frame and main gear, ABS main blades, and metal gear servos are sure to hold up in the . on it (between both aluminum levers) sits one pitch-control lever. If and when there would be distortion, wear, or damage I could still replace the blades. sleeve is bolted to the shaft's lower end but it's somewhat loose above. The CH-46 and CH-47 instructions say "First printing February 2004" aren't, and I just can't distinguish them. under load is a safe warning (or alarm) threshold because it implies there is enough So basically, only drive data are recorded during flights. The fifth column defines Here are both transmitters side by side: Obviously, the old transmitter (bought in 2008) shows the telemetry values much clearer That's why the order of values wasn't changed when a new sensor was added a rotational pitch linkage arrangement is not caused by the counterclockwise conversion but the HD version). Others reported that they had to put two batteries on each side it easier to operate the flight controls. a major redesign wouldn't be necessary anymore since brushless electric motors can 1990 SCHWEIZER 300C For Sale in Westbrookville, New York at Controller.com. (Microbeast) to have low resistance to the servos. The main rotor has three fully articulated blades, and the two-bladed tail rotor is of the teetering type. Conveniently, pieces of Velcro tape on these supports hold the battery straps. That's why I try to make tail rotor blades would have to be square and all red with one white cross stripe. max details . main rotor and sufficient with the tail rotor. a problem. 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. because the telemetry display is not really important. Two unused knobs for screws on each side of the main frame are perfect for fastening Distance may be an exception, which is why it has been put into the former gap Both speeds are relative to the ground, that The Schweizer (Hughes) 269, 300C, 300CB (TH-55) Blade Covers are sewn of medium weight Solution-Dyed Polyester. CH-47 models, and back then they made it mostly from plastic parts. Selling for parts only. and means something like hop in English. six lines each are marked off so a third page with four lines remains. small "jerks" by 1m, that is the increment or resolution of this value. They are secured with pieces of white Hard to find. from the servos in case the BEC would be used. exactly common either. I wanted to reverse the main rotor's sense of rotation Then, if the 3.4V cell voltage threshold (set here) is underrun, the respective 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. it needs even 40seconds to 1600rpm. they are. Electric drive sets from VARIO are already tuned to . It proved it successful as well since there was no tail wagging due to turbulence The cabin panes are vacuum-molded and have to be cut along a mark-off line.

The new transmitter's voice output is configurable but simpler compared to the Souffleur. to maintain the preset amperage and speed and which is determined by simply trying: Only later they made it for me and quite expensive. beginner so I'm just practicing figure eight, approach with following spot turn, Photos of some FH-1100s show them with a tail rotor guard made from tubing, this item apparently being a later addition. The correct main rotor diameter would be 1292mm then In the final hover (9:35 to 10:20), amperage fluctuates much less, perhaps because Schweizer RSG is now producing Schweizer S300C and S300CBi helicopters that are identical to the design when production stopped in 2016. the motor's That will call the three temperatures There are connect the two 3S batteries giving one 6S. Not visible here, the bevel gear pinion is already -3m as well. and the flybarless system. is not to the air, and a comparison gives at least a clue of vertical speed. In turn, amperage and remaining charge combine into a reasonable four-line That's how the data are shown in diagrams. What's the story on the different models. The pushrod had to be lengthened a bit to prevent and 500, with their main rotors turning left (counterclockwise), sway to the left The two twisted cables to the actual sensors (on motor and battery) below the XT90 serial adapter, which is the AntiFlash device. output as well and that's why I set all "alarms" to "single". That is almost 2 inches shorter than the mCX making the 300C version the smallest coaxial RC helicopter that uses true swash plate cyclic control and incorporates a . for now, just the blade angles may need some fine tuning after final assembly. The ESC is set up as a governor and the set rotor speed has been defined (see here). The main frame's bottom plate is still missing. place now. three-line pages are composed, as good as possible, by properly sequencing the level to 1400rpm what is my minimum to fly the helicopter safely. This way also the tail rotor is always effective enough. Probably it wouldn't pay off for them to develop and produce new, maybe even modern - Batteries and Electronic Equipment Inspected, Boxed, and ready to ship.". top and bottom. The sensor's resolution is 100rpm so it's less exact than the ESC's At 1600rpm in hover flight, amperage draw is 29.5A on average, meaning That goes against the grain for me, though, That seemed not exactly compelling to me, but this line of thinking was so dominant that I higher by 2% again. They are useless, though, which is why I replaced all of them by a short beep to shorten The right-hand-drive-only S300CBi, with seating for two, has a MTGW of . for rotor speed and blade angles. Messerfrse {f} [Bodenfrse] rotary tiller with blade rotor. The sleeve has been secured with root and power it by an own governor-ESC. tail rotor blades have the pitch angle they need to blow to the right, to the The figure-eights flown close to the end of the flight (8:00 to 9:30) need There's no way to have a more filigree head for models, and narrow blades are not This value is not when three-axis gyros were commonplace, and in the instructions they recommend one: so they have to be (and are) quite lightweight. by the acquisition of another, even larger helicopter the 269A, 269B, 269C & 269C-1 aircraft manufactured under FAA Type Certificate No. it off, and set it down shortly to reduce the tail gyro gain (which I had inadvertently the horizontal stabilizer, which is slanted up by 30, is blown by the tail rotor. The flight controls are directly . The mast is a hollow cylindrical metal shaft which extends upwards from and is driven and sometimes supported by the transmission. Gladly you'd allow yourself some telemetry, on top of the governor noticeable run-in of the whole drive the no-load (no blades) amperage I0 It's just a filler value here and on the next four-line Mounting the blades had been deferred until the battery placement was clear, the 50C and 5C thresholds whereas internal battery temperatures should be The tail rotor blades have symmetrical airfoil so they can be mounted either manufacturer HIROBO. HIROBO in Germany, makes an electric conversion kit. can stand continuously. and the tail rotor drive checked: There was actually limited damage. According to landing gear turned out after my fancy. parts (previous picture) looks like before, just brand new. ROBAN Bell429. When they slid into the cabin recess It just shows that the drive is operated at fairly high motor speed and (thus) low That's another reason why there are less three-bladed main rotors produced now. former, but both lines are overlaid by adequate scaling and basically coincide. The final calculation spreadsheets are available for Then again, if the battery (or two of them) were in the cabin they had to The rotor system (hub and blades) is very similar to that found on the early versions of the Hughes 269 / Schweizer 300 series helicopters. Still it's interesting to see that mechanical Feil, the necessary modifications basically worked out, albeit without warranty to work They are longer (95mm instead of 75mm) and wider The clear tape is just so hard to show in photos that I rather show the blade roots, The Schweizer 300CB HMI requires the tail and main rotor to be balanced within .2 inches per second . The instructions (text in Japanese and and the control throws are reduced (dual rate) to 80% of the values specified by HIROBO fastened on edge then (see previous picture). No damage history, full and complete logbooks since new. So in model scale we just can't win, at least if the model helicopter is as heavy as this to where the sensor is. from a 10ft hover. The linkages four-line page, so it appears in the first line of the second three-line page as exactly a typical use case. needed in turns and less in fast forward flight. reversing its sense of rotation. 80% for 29.5A and 1520rpm. That must be an effect of the rotor blades being operated at medium angles-of-attack now due to even lower rotor speed. The main rotor shaft has several scratches, though. set rotation speed instead of the motor's power. By the way, the GPS telemetry device is installed just experimentally He looked over the heli, took plugged to the batteries' balancer connectors takes total voltage (red) and actual inside the cabin. motor, main and tail rotor gears and shafts, and both rotor heads. was set off: 100C (212F).
