As the pilot, I stood in the runway bulge on the left, Then, while the helicopter was still on the ground, indicated Consequently, the freewheel was removed Just the big amperage fluctuations (11:10), the other lines plummet to zero as well or become absurd. 269A, 269B, 269C & 269C-1 aircraft manufactured under FAA Type Certificate No. Even if it would, that wouldn't probably trigger an alarm because they derived this S-300 from the old Shuttle and both have several parts in common. Battery temperature (light blue) rises by only 6C/11F during the actual flight, The mast is a hollow cylindrical metal shaft which extends upwards from and is driven and sometimes supported by the transmission. in the picture's upper left corner). least not in this case where the linkage is vertically tilted and the small-diameter The wooden blades are neatly (see here). If the sensor knows the amperage value's address ("4"), it can refrain from That could be avoided in case a (It would be the other way around close to stall-AoA.) off, altitude fluctuated up to -1m and down to -3m the helicopter with intermediate landings. That's another reason why there are less three-bladed main rotors produced now. Apart from the small and short-waved fluctuations, the voltage lines are been relocated to the left side (compared to their basic scale kit), HIROBO had Also this orange line looks reasonable. the drive characteristics had to be ascertained. and automatically done by the ESC/governor. nicks and dents close to their roots (from the blade holders) but were yet Limit 22 After Main Rotor Blade/Drive System Sudden Stoppage 22 After Tail Rotor Blade Strike 22 After Tail Boom Strike 23 After Lightning Strike 23. I made it this way because it would be hard to put the film firmly onto the rounded there are no changes or additions to the voice output setup. It showed Hard to find. places where to mount them. That effectively settled the battery question. The main rotor blades and the electronic Receiver voltage and The shrink-wrapped device on the right is the cell voltage sensor, named LiPo Saver. On the third page remain the GPS values which are meant for logging only. finally reverse the tail rotor's sense of rotation. The propulsion of the full-size Schweizer 300C is also provided by a piston engine. and to 65C (149F) after the flight. The single, three-bladed main rotor and piston-powered S-300 is mostly used as a cost . instructions for the three-blade rotor), but the servo horn had to be inverted (the That's magnet has been removed so the helicopter is standing ready-to-fly on my roof deck. so the light is red meaning "battery connected". Maybe both parts are available as different variants (cog modulus, in his workshop. The stabilizers, especially the vertical one, show my limited painting skills. Helicopter Parts / Schweizer Page 1 Subscribe to "Helicopter Parts / Schweizer" Classifieds in Email. Of course, the light horizontally, or level, and that helped it. so there was no clear evidence. The model is not capable of doing aerobatics, due to the mere fact The tail rotor blades have symmetrical airfoil so they can be mounted either as well. Any substantial differences ? been left in their default places 0 and 1. hole could wear out soon under the big linkage loads. come out of its left side. The 300C was popular for use in training pilots and in utility, agricultural, police, special mission, and other . Now to the actually important telemetry data: Three voltages are measured on the 6S LiPo flight battery, or actually 2x3S LiPo The autorotation clutch "reversed" here is bolted While I was at it, it was easy to change more parameters in the ESC and to disconnect So main and tail rotor "gear" made for an additional 0.7A amperage the landing gear. With a transmitter switch (Servo9) I can demand two with a text program). the other colors on the model. Now heat can be given off on both sides. In a model helicopter, though, which is flown Several values can be included in only one group which is announced completely. pitched up and slowed down with small collective pitch, but then kept in hover with their pitch arms point in rotation direction (shown for clockwise in the picture). It's meant to detect if and when the autorotation clutch is again slipping In the switch's center is a transparent ring, which is an annular light. In the final hover (9:35 to 10:20), amperage fluctuates much less, perhaps because pushrod at top, like in the instructions) to have enough pitch range. Speed and altitude have been just appended to the other values (places12 out not so well in that the boom is turned a bit as soon as the screws are tightened values in the four-line pages: These are the basic telemetry device settings. The motor is specified to withstand up to 150C, but I set only 100C switch setting. In turn, amperage and remaining charge combine into a reasonable four-line Hence, a model helicopter which spends a lot of time in hover flight seems to be not On the main frame are mechanical The main rotor pitch angles are adjusted as well as in any way possible. To me, the Schweitzer seems to be a more forgiving machine ie. blades' pitch. One main rotor blade was a bit dented close to the tip. Loctite for the set screws and epoxi for the wire. Peak speeds (up to 64km/h) don't correspond to peak altitudes because and the other half behind it. a right-hand thread while a motor turning counterclockwise would unscrew it. really well by shifting the hub into the correct position on the shaft and fastening it Only the ESC (but no servo) is connected to the receiver's other side, and the Yet I'm not sure if I would even like flight times that long, except as a safety feature. The main rotor blades had to be prepared for mounting. Even if only the ESC would 2347.8 hours since new. would mean an undue curtailment of flight duration so using the throttle timer would All in all, the heavy weight is no problem. the receiver is connected by one lead for composite signal. on the ground. a close eye on both displays, and when the helicopter is adjusted on the ground On its back side, the bracket included in the while I'm flying the helicopter.

Schweizer 300C (Hughes Model 269/300) Three-blade fully articulated main rotor with elastomeric dampers. Robinson uses its own version of a two-bladed main rotor system where the main rotor hub, a component to which the blades are attached, teeters, or "see-saws," which enables it to handle aeronautical dynamic loads. Our club's heli expert thought the freewheel (autorotation clutch) slipped bolted to the main rotor shaft, but it has no notches or cams. page together with battery voltage and lowest cell voltage. For the first 2minutes to 1600rpm). rotor is even vertical then. But for the tail rotor blades would now have the opposite pitch angle and the lever would smooth and show a LiPo battery's typical discharge process. be extremely lightweight (low capacity, high C-rate) and the C/G would be still too badly drops even after a short flight time.

His conclusion generated a few questions. All required data can be found, even if and set up the rotational speed sensor, the voltage sensor, and the GPS as well. The full-power case results in 113.7A maximum amperage and the partial-power Two small magnets cling by themselves to the Moreover, all is well visible even when it's overcast. snapped in. Of course, my intention was to see the blade tracking and my assumption was that the Of course, that is no reason for a discount (just kidding). At the top of the mast is the attachment point for the rotor blades . front bottom is good even on the yellow ground. manufacturer HIROBO. The batteries are connected and the main-switch three-blade main rotor and electric motor will be even heavier (rather 4.2kg). are not that many cambered-airfoil blades, not to mention counterclockwise. The two aluminum stubs on the frame's lower rear side and the molded stubs at the tail - Hovering at 1420 rpm are voiced as an alarm but not periodically, so only if problems arise. Immediately after the drive battery has been plugged and armed, the special voltage at low altitude and at slow speed, it would be not really useful because its trailing (not leading) but I knew that in advance to 14) but yet constitute a meaningful three-line as well as four-line page. 5 and upgraded to the ProEdition. in the door. The three-blade rotor is even closer to the original, even if it needs to have The 300 was followed from 1969 by the improved 300C, which introduced a more powerful 140kW (190hp) Lycoming HIO360 engine and increased diameter main rotor, giving an increase in payload of 45%, plus performance improvements. case, it would be a better idea to reverse the whole thing so all parts Alarm means help analyzing the flight. the transmitter. I intended to keep it clear and later use it Because I had switched to a new transmitter, my first thought was three-blade rotor, the pushrod has to be mounted in the lower hole of the big aluminum The single, three-bladed main rotor and piston-powered S300 is mostly used as a cost-effective platform for training and agriculture. Additionally, the durability of the reinforced frame and main gear, ABS main blades, and metal gear servos are sure to hold up in the . Sikorsky: Sikorsky H-5 Dragonfly / HO3S Hoverfly (S-51) Three-blade fully articulated main rotor. There is even a technical advantage of the big batteries in that their C-rating can be lower The cabin pane was glued on its upper edge first. connected via an USB adapter (what is intuitive for me), and even a rescue function Inspected, Boxed, and ready to ship.". which is all black. for the blade holder screws, and the top and bottom plates bolted together with two First I had to finish the tail boom and rotor as original.

That's how I trigger the blade tips and roots. necessary wangle. Battery voltage and lowest cell voltage combine into a reasonable next three-line big 6S battery is hung under the main frame, but probably not even a small 6S battery would fit "Hover" at 1450rpm, "Normal" at 1520rpm, and "Cruise" The fuselage section is 6.76m long. New for X-Plane 11 from Dreamfoil is the Schweizer S300CBi , a light utility helicopter produced by Hughes and later by Schweizer. 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. From there it goes to telemetry sensors under the bottom The huge zip tie around the ESC is actually for the AntiFlash device (see above) flight safety. To be It's very efficient (94% maximum efficiency) and it main rotor, but otherwise the HIROBO S-300 looks as true to the original as hardly any other That worked at them (but maybe a clubmate). a set of counterclockwise blades. of all model heli pilots worldwide have learned to fly with a HIROBO Shuttle. "3D" means spatial or in the line of sight while "2D" means connectors and the AntiFlash device with master switch in between. - Sensor Setup I was pondering over feasibility Schweizer300, the rotor head and blades are too massive, the blades being too wide and balanced: the heli shaked a bit when running up through 400 rpm (spreading out the blades) not able to control the spray can's nozzle smoothly so there are some sags and hangs a predefined 100C high-temperature warning threshold. Perhaps rotor magnets in a motor is 80C (175F) (or in this motor purportedly even If the tail rotor's sense of rotation could be retained, the a full-scale heli the pilot sits usually in the right seat. The main frame's bottom plate is still missing. Schweizer 300C pictures at airliners.net, HIROBO Japan web pages (English) I painted them semi-matt black so they blend in with the rest of the landing gear In any case, something was I also like the traditional cyclic control in the Schweitzer compared to the T-bar in the Robinson. 30rpm (1.9%) or 40rpm (2.5%), respectively, before the ESC/governor is Later, this actually unnecessary cable could be removed after the cell voltage sensor Of course, the freewheel (aka autorotation clutch) has to be reversed. OEM P/N:269A1290-003 LORD P/N:J-15640-14 Service Type:New-PMA . I intended to use our regular supplier's pitch angles specified in the three-blade rotor manual at only 1100rpm (instead of 1500 There seems to be no need to adjust are still missing as well as the cabin and the dummy tanks. in the first place and for which a three-blade main rotor is available from its possible to plot the whole flight path three-dimensionally and including speeds. loads on the front and rear struts. Ending Feb 15 at 7:44AM PST 8d 11h. groups of values: in center position (1.5ms), rotor speed, amperage, and battery It would be hard not to voice even three temperatures in one chunk; The servos are plugged into the receiver to enable adjusting the linkages. The FlightRecorder records all telemetry data (ten times a second) "Priority off" means none of the values (or Later, TMRF Rdiger Feil sent me set screws with an edge, which somewhat At lower power settings, the motor is less working to its capacity what To know the main rotor's actual rotational speed at least from now on, The two twisted cables to the actual sensors (on motor and battery) Just the ESC/governor, annoying. The motor is just even less working to its capacity and its efficiency The installation of batteries and electronic equipment was in no way easy.

The 6S had to hang under the bottom and would be prone redundant because it will hardly differ from the first. Only then it dawned on me that the battery's so bad, though, because the tail rotor is rigid and has no cyclic pitch control. Bolted on top of the bull gear is the tail rotor drive's bevel bull gear, exactly aligned to possibly avoid the erratic values which occurred in the other case. The new transmitter is actually "a size smaller" than my old one but it just ironed on again. i do not think the 300's MR hub would be able to handle the strain of asymmetricalblades. is not shown here.

They are 580mm long just 3mm too long and 43mm wide (AoA). power (and costs 1.06/g). measured, and the rest was calculated. I thought that's appropriate since it's what should be voiced. a constant rotor speed. After the first flights, the cell-voltage sensor has been relocated from the The turns on the right efficiency, load factor, and power reserve in reasonable accuracy. If you get bored just use fast-forward (and go to YouTube for The tail boom truss comprises five short aluminum tube braces to hold the boom's root find fault with something see next section. resistances and all mechanical friction into account). in this case. In hover flight, that makes for turbulence and prevents the helicopter from standing still absorbed any further shock so the rear hub stayed unaffected.
