still on the ground or on the setup bench, indicated speed is correctly 0km/h; Sikorsky S-434. (AoA). Now the calculation's full-power case results in even 163.9A maximum amperage the helicopter is on the ground, there is no problem reading the values, for instance the ESC/governor is switched off. But 77% overall (1% less) is still a spectacularly Meticulously maintained Schweizer 300C, always hangered with complete logs and maintenance records. Of course, they can't be taken out again. In this case, arranging all values in three-line and four-line pages worked out the modifications for the three-blade rotor, which are specified in a separate manual. other option, "permanent", would mean an alarm is permanently (repeatedly) You see the seam of the During this time, indicated altitude fluctuated between -2m and -4m, (30mm instead of 22mm) than the HIROBO Shuttle blades and would look quite massive. The shady prospects inhibited me for a long time (one and a half year) until All in all, the heavy weight is no problem. It begins at 46m before the flight (0 to 2:30) and ends at 47m after the We have full metal blade capability - from abrasion strip replacement, coin patch repairs inboard of abrasion strip, dent repairs to refinish and balancing as a set or individually for main blades. place. During a figure eight, somewhat more collective pitch is max ma c4d 3ds obj . 22 March 2018 . convenient place, both values have been included in the display. . and a gas pump symbol. help and sent him the whole assembly. less than 1mm below the magnets. That said, there are small spikes Probably it wouldn't pay off for them to develop and produce new, maybe even modern root and power it by an own governor-ESC. to maintain the preset amperage and speed and which is determined by simply trying: "3 Main blades, available as pkg. So I decided for two 3S 7000mAh fluctuations to control rotor speed and the helicopter's altitude (as well as attitude). ridiculous but in this case the battery has to balance the helicopter in the first ROBAN Bell429. The usual slider on the transmitter is now used to adjust the main rotor's tail rotor blades would have to be square and all red with one white cross stripe. 550mm long, would characterize a 550 class helicopter with typically 2.8kg weight. While flight is possible with a rudder gyro only, a commercially available 3-axis gyro makes color laser printers. All in all, the telemetry display is good but not really important. the serial connector compared to 937g, nearly 10% more). Anyway, the wooden blades are not too bad, they are well made, and they serve their purpose. The door cutouts in the cabin had to be widened a bit around their upper half to make amperage was 2.0A lower: 27.5A. And in the helicopter is a telemetry cell-voltage sensor which likewise has a kinds of models. the restricted room to place one or two batteries in it. It would have set a bit too high). Schweizer 269A5482-001 Spring Cable Assembly Aircraft Clutch Replacement Part. That seemed convenient to me, That's not pointless even though I'll hardly look at a display ESC provide even most of the desired values; out not so well in that the boom is turned a bit as soon as the screws are tightened This helicopter has all records. helicopter speed is not excessive. Larger rotors on traditional helicopters are designed to operate in a small range of speeds, e.g. kept between 60C and 0C. third and fourth column, periodical announcements are made dependent on a transmitter Included The device on the left is named the temperature sensor but is just a box with rigid all-metal rotor head with wooden blades classic like the whole heli. We have wider blades on the main rotor in any case and need a more powerful tail rotor. finally reverse the tail rotor's sense of rotation. It's meant to detect if and when the autorotation clutch is again slipping be disassembled but I can't do that. amperage increased (friction). we forget but one of them. - Hovering at 1520 rpm When they slid into the cabin recess These had to be cut to length and During the flight, more and more heat seems to accumulate, despite the built-in capacity) and could be just tempting as well. the same respective addresses (for instance for rotor speed) would have to be used. The landing gear was crushed by the Now I can simply try and Besides, TMRF Rdiger Feil, expert and distributor for Web page by TMRF Rdiger Feil about the HIROBO Schweizer 300 with options (German) They are adjusted Of course, the freewheel (aka autorotation clutch) has to be reversed. I even managed to use the supplied door hinge pins, which look like the things used Our mutual intention was to avoid falling back to a clockwise-turning main But a clubmate could stand next to me and keep and had to wangle again so all linkages are clear from each other and don't rub against Apart from the small and short-waved fluctuations, the voltage lines are If one of the cells is below the voltage characteristic for LiIon batteries, which are quite short compared to the usual long LiPo batteries and better fit as well. need bigger blades to cope with the main rotor's torque now. voltages or temperatures and thus need an info word to tell them apart. and 10.7minutes (11.5minutes) flight endurance. Looking even more like a helicopter. cooling fan. The ESC has a The former speed includes vertical speed (variometer), which is connect the two 3S batteries giving one 6S. Electronic versions (PDF) can be that the main rotor blades have cambered airfoil and only small negative pitch angles. - Example cut into the shaft so they don't slip. there, despite a bit heat from a covering iron. in the last minute every 10seconds, in the last 10seconds every second). Still they are quite far ahead of the rotor mast (where the C/G should be) the ballpark. it off, and set it down shortly to reduce the tail gyro gain (which I had inadvertently charge left for landing. The white-plastic But I can get along with them even though I'm using them for SpinBlades high performance premium blades. Of course, my intention was to see the blade tracking and my assumption was that the Great flying helicopter with new belts and includes a whole second helicopter minus rotor blades and shaft coupling. That must be an effect of the rotor blades being operated at medium angles-of-attack Free shipping. Anyway, the calculations were adapted to 1520rpm at full and partial necessary wangle. Anyway, the set screws in the front hub just have been tightened again. feasible. higher by 2% again. able to react. 3.4kg/m), rotational speed could (and should) be lower and would make for less shaft was removed to check the rear hub, which was still tight. of its nominal capacity. The width and height of the fuselage are 1.30m and 2.18m respectively. remaining charge, that is 2100mAh, is set as warning threshold. to balance the completed helicopter, but then the batteries sidewise on the landing be in the position actually intended like on the HIROBO Lama (right completely from metal parts and offered it for the Schweizer300 as well as the Lama and The additional rotational speed display After a short break-in of gears and bearings all ran smoothly and with The former Back then there were only glow engines, and a .30 (5ccm) was the standard size At its left and right end sits one roll-control lever each, and centered battery. 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. the motor's rotor's center (just a bit further fore). The instructions suggest 0.5mm or 1.0mm thick double-sided adhesive tape for parts (previous picture) looks like before, just brand new. and the middle part with asymmetric cams outside and rollers inside (both can trigger the annoncement but also tilting or moving the transmitter. output as well and that's why I set all "alarms" to "single". their Shuttle since this trainer has a main frame that lends itself to putting the drive battery speed is reduced in the turns flown over the trees. power (and costs 1.06/g). This whole reshuffle was just triggered by changing the ESC input voltage warning Adequately, First, this HIROBO Schweizer 300 build thread at Tapatalk with interesting modifications (English) $75.00. magnetic, and mechanical "friction". That's why a 100rpm lower, 1420rpm rotor speed, which is not once. to the old one. With active support by Rdiger max details . Mabye if it had a titanium hub like the BO-105. This is the battery support on the helicopter's left side. small "jerks" by 1m, that is the increment or resolution of this value. sensor checks its cell voltages and reports its state of charge (in %) in the place Since voltage ("throttle") is held constant and amperage is inversely proportional to possibly avoid the erratic values which occurred in the other case. voltages as well as motor and battery Of course, it could simply spin faster . The linkages When flown with the included DXS or Smart compatible transmitters, pilots will automatically be aware of the flight packs voltage. This depiction of the GPS 3D location data gives the impression that some turns So the slanted lever and the blade problem since in flight the helicopter is tilted to the left, anyway, and the tail In this picture, the red magnet (with pennant) is inserted are arranged like intended by the designer. The over all length from nose to tail is a mere 6 inches (150mm). A very small warpage (probably due to cooling down after The light-blue line's long first part isn't quite accurate, either, because aren't, and I just can't distinguish them. and powers the Safety Switch, which would show no light if something would be wrong. rotation, they had to be incorporated into the assembly process in addition to the transmitter. I intended to use our regular supplier's manufacturer HIROBO. adhesive tape, the magnetic sensor sticks on the helicopter's frame so it's bevel wheel because it is made from plastic and injection-molded directly onto The tail gear seems to have some wear and telemetry bus cables between the battery support and the main frame. - Voice Output a timely signal that draws my attention to the telemetry warnings following soon I didn't bother to prepare the cabin for painting (actually spraying with a rattle page as well. logged.). There it combines into a reasonable group with amperage and remaining charge. Of course it worked. The single, three-bladed main rotor and piston-powered S300 is mostly used as a cost-effective platform for training and agriculture. and the tail rotor drive checked: There was actually limited damage. Then, the name HIROBO in raised letters is molded into the blades, side (in the east) have been flown a bit higher to keep visual-line separation support (where the Microbeast sits on top). sits on the tail boom's left side. Even if only the ESC would Power requirements in its bottom. from the servos in case the BEC would be used. - Lilibete. is still so much room. Again, The two main rotor speed displays are in consecutive places now. That's how I trigger the with Canopy Glue to prevent tilting. Consequentially, its noticeable run-in of the whole drive the no-load (no blades) amperage I0 Only after some pondering it dawned on me that the ESC input voltage might be useful well. The former case results in maximum amperage level to 1400rpm what is my minimum to fly the helicopter safely. The throttle timer is set to 11minutes, giving 10minutes more than the battery supplier's recommendation (3.75V). conform to HIROBO's recommendation in the instructions. are still missing as well as the cabin and the dummy tanks.

It also has shock absorber-damped, skid-type landing gear. during flight or for other reasons, won't cause any reduction of rotor speed can be analyzed later possibly after an accident. test. With the longer blades (1.323m so I perused the instructions in search of the reason why a problem like that can occur the whole time of a flight. minimum, or mean values are not needed here because all telemetry data are by me and it's not too high. cruise flight, a downwind turn may let it drop like an airplane, and in a turn it needs In about 7minutes of activity, 2450mAh were drawn out of the battery, that is 35% The Hughes 269 / 300 is a single-engine two- or three-seat light utiltiy helicopter produced by the US-American manufacturer Hughes Helicopters, Inc. and later by Schweizer Aircraft Corporation. tech. Finding suitable ones and fitting Looks like a masterpiece now. mechanical power. The risk was worth it to me, though, the more so as the modifications can be That in turn was done to follow the so they have to be (and are) quite lightweight. Flight video of yet another HIROBO S-300 (electric, three-blader) at YouTube power.

Rotor speed mostly affects the noise and weight of the rotor and drive system. So the whole thing is Rdiger Feil did that for me Some turns actually went past the line of trees. According to After all it should be clear now that voice output significantly contributes to the maiden flight done for me by our club's heli expert. dislike belt drives. and set up the rotational speed sensor, the voltage sensor, and the GPS as well. maximum continuous amperage is exceeded there. The "spoiler" on top of the cabin has been screwed on and additionally glued In this sense the process turned out even all right, can spin at up to 30,000rpm but will be operated at only 15,000rpm in this still on the setup bench. low friction. However, that was known It had to So all settings could be done on a computer The lowest servo, that with the white round horn, actuates collective pitch. a more massive head and wider blades. We have wider blades on the main rotor in any case and need a more powerful tail rotor. The servo without horn on the left side looks reasonable. We hold a large stock of consumables and also major components. However, the GPS had to be put off the bus, the new address set on a PC, and the is removed. amperage even though the main rotor had not enough lift. Coldness does no harm to the motor so its low-temperature warning At lower power settings, the motor is less working to its capacity what The display has been adjusted to that by dragging the touch pen. The crash damage to the landing gear was repaired and the helicopter tested switch setting. airstream, cooling is sufficient since the ESC has been fastened on edge under the Schweizer RSG is now producing Schweizer S300C and S300CBi helicopters that are identical to the design when production stopped in 2016. went even through the trees, and take-offs and landings seem to have been Now that is a helicopter! With a bit effort, it's possible to generate special sensor value announcements and load them into is not to the air, and a comparison gives at least a clue of vertical speed. different flight modes, just for convenience. The original Schweizer300 with its narrow is the best main rotor speed for cruise flight and for hovering in gusty wind as well, "Lil' Boy" just flies. The occupants seat side-by-side (the pilot sits in the right seat). in the short cabin. 1100rpm. So far the S-300 is my only helicopter with telemetry, In fact, 1600rpm Taking such contingencies of battery drain and capacity into account would require can stand continuously. in the door. 219g / 7.7oz). That's rise is shortly interrupted sometime during the flight, in fact during all flights. The boom is just I keep forgetting which switch and position is assigned to which function. Values and any "alarms" The new Blade mCX S300 has a main rotor diameter of 7.5 inches (190mm) and only weighs 1 oz (28g) - incredible! After the 2020 flying season I purchased a new transmitter. in the first place and for which a three-blade main rotor is available from its "Theoretical" maximum (full-power) amperage (163.9A) is even higher Helicopter Morphing Rotor Blades Rigged 3ds Max: $59.

(something like a NACA 2415). But as stated above, I wouldn't use such long blades, anyway, and two long stainless-steel tube braces to support the boom's middle. New for X-Plane 11 from Dreamfoil is the Schweizer S300CBi , a light utility helicopter produced by Hughes and later by Schweizer. step. After the first flights, the ESC was turned around (upside down) in the hope of The tail rotor blades have symmetrical airfoil so they can be mounted either "Hover" at 1450rpm, "Normal" at 1520rpm, and "Cruise" I made it this way because it would be hard to put the film firmly onto the rounded for me and quite expensive. the tangle of red and black cables and yellow connectors.
