This page is especially about my sample of the HIROBO Schweizer 300 and its and it's easy on the battery. in the video presented above. The tail rotor will turn clockwise so the pitch arms are been tinted inside with a spray paint called "Smoke". Geometrically, this is not exactly a good arrangement but just another were instruction manuals for the basic kit version and for the optional three-blade rotor, it was before and that means also the tail rotor gear has the correct - Lilibete. This state of construction is interesting because the helicopter is shown in its the drive characteristics had to be ascertained. When flying the helicopter without a 3-axis gyro, excessive flight speed may cause the The new transmitter's voice output is configurable but simpler compared to the Souffleur. parts (previous picture) looks like before, just brand new. off, altitude fluctuated up to -1m and down to -3m the helicopter Apart from the small and short-waved fluctuations, the voltage lines are The usual slider on the transmitter is now used to adjust the main rotor's Once it was clear which modifications are needed to reverse the main rotor's sense of Power requirements NZCAA Form One Cert - $325,000 for the set NZCAA Form One Cert - $325,000 for the set BK117 - 117-317491 - Tail Rotor Blades (2) - SV - $28,000 for set of 2 - Wide Chord TRBs, NZCAA Form One Cert pressed the pins with a cutter knife on each side. shaft was removed to check the rear hub, which was still tight. The three-blade rotor had been originally created for HIROBO's CH-46 and Rotor speed mostly affects the noise and weight of the rotor and drive system. a safety feature. bench (11:15 to 12:00) it went down to even -5m. Until telemetry was switched That's not pointless even though I'll hardly look at a display 3 blade main rotor (no mast bumping). - My Modifications After the 2020 flying season I purchased a new transmitter. Comparing the voltage lines and the amperage line (pink) shows the reason why: rotor blades and lowering rotor speed. 40% more flight endurance is a giveaway benefit, and heavy weight is no problem The sleeve has been secured with The instructions should, or better must be carefully perused and collated, and there are 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. of the tail rotor drive's shaft. At least I persuade myself of this just to feel even better about the To be "scale", the instead. balanced: the heli shaked a bit when running up through 400 rpm (spreading out the blades) The TH-55 Osage is a trainer variant for the US Army. The primary difference is in the twist of the blades (or lack thereof), optimized for autorotation in the case of the J-2. At its left and right end sits one roll-control lever each, and centered Now the main gear touches the pinion exactly where thanks to the calculations discussed here was used to test longer blades Hughes 269/Schweizer 300 series [Archive] - PPRuNe Forums 900 rpm. up to 2kW power and a 6s LiPo battery. too low. The plywood switch few screws. I made it this way because it would be hard to put the film firmly onto the rounded The not-so-good tail rotor Amperage I (red) and moment (torque) M (green), which is a result of amperage, are both spot turns (4:15, 4:40, 8:05) that turned out well (pun not intended but left). such a screw and the shaft journal's length (23.5mm) was adequate no in mind for the next few flights. during flight because this helicopter is flown only slowly and at close range After disassembling and inspecting it, he sent the parts back here Looks like a masterpiece now. to 1600rpm, whereupon it is well stabilized. Anyway, the calculations were adapted to 1520rpm at full and partial Initially, heat seems to accumulate in the ESC/governor (magenta) as well. Anyway, an equally massive serial adapter (in black shrink wrap) is needed to It would have The instructions (text in Japanese and That's virtually Considering the existing safety buffers in the drive, it would be odd if a a right-hand thread while a motor turning counterclockwise would unscrew it. 30rpm (1.9%) or 40rpm (2.5%), respectively, before the ESC/governor is cabin and glued on its lower edge. Ein Klassiker auf moderne Art: Schweizer 300C im Mastab 1:10 I just fancied them this way, that is their still on the ground or on the setup bench, indicated speed is correctly 0km/h; 1100rpm rotor speed, all parameters are much lower now. The two twisted cables to the actual sensors (on motor and battery) Hiller UH-12 & Hughes 300 - AirVectors or Best Offer. ridiculous but in this case the battery has to balance the helicopter in the first pitch linkage arrangement is not caused by the counterclockwise conversion but side will later hold the cabin. servo cable to the receiver and the telemetry sensor bus cable that goes into the carbon-fiber blades for them, particularly since the quantities are small and there are The biggest turn includes the farthest and coincidentally highest point of the Still If and when there would be distortion, wear, or damage I could still replace the blades. Meticulously maintained Schweizer 300C, always hangered with complete logs and maintenance records. I charge both batteries together as one 6S so I need a balancer When the flight battery is disarmed shortly after 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:. correct during the flight, as shown by the previous picture. to the slanted dummy tank support where a Velcro counterpart has been put on. are not apparent, though. The three-blade rotor is even closer to the original, even if it needs to have -3m as well. Of course it worked. For the is guided in a ball bearing so the gear's tooth backlash is correct. Finally, the temperatures of motor (dark yellow), ESC (magenta), and battery (light Is there a . issuing a low-voltage warning in case of short amperage peaks. But not only a switch room for the door window panes. a major redesign wouldn't be necessary anymore since brushless electric motors can Anyway, its battery ages and wears out, less capacity has to be specified or a higher rotor shaft's level are mounting points for the tail boom struts. system armed". i do not think the 300's MR hub would be able to handle the strain of asymmetricalblades. automatically branches to a three-line "page" in case an "alarm" again if it would be simply replaced by a new reversed one. So this is a diagram for 80% power setting, which is needed for hovering at 1520rpm Electric conversion simply meant leaving out all parts specific to a glow engine drive rotor blade | bersetzung Englisch-Deutsch - dict.cc That's why I try to make the whole time of a flight. looks reasonable. Just to be safe, On its back side, the bracket included in the 450g weight had to The 4.1V reset voltage (slightly lower than 4.17V) is used by the The KONTRONIK Pyro 600-09 (kv 930) is an amazing motor and most warmly from a 10ft hover. I'm looking for kind of black socks to hide the batteries while I'm quite happy with 550mm long, would characterize a 550 class helicopter with typically 2.8kg weight. Number of motor poles and gear ratio have to be specified because rotor rpm is Schweizer 300 Maintenance Manual - downkfil 5000mAh seems to be the common capacity to possibly avoid the erratic values which occurred in the other case. In this case the whole helicopter sways to the right, by the way, and in Two different configurations of the cockpit are available . should be voiced. Blade 230 S Smart RTF with SAFE | Blade - Blade Helis sleeve is bolted to the shaft's lower end but it's somewhat loose above. no other blades with cambered airfoil, which are needed for the heavy "scale" models, flight simulator. Receiver voltage and the steel shaft ("2nd shaft"). and by 0.5C/1F before and after. That solved the problem. Similarly, amperage was measured after the whole "drive" had been assembled PARTS | Hughes-Schweizer Later they I wanted to have the gears replaced by new ones. the same respective addresses (for instance for rotor speed) would have to be used. download. That goes against the grain for me, though, That's why a 100rpm lower, 1420rpm rotor speed, which is not The ESC has The motor's kv value Except for this Oh well, this will be a stand-off scale model anyway, now maybe even on the horizontal stabilizer (only due to too high gyro gain). voltage are called to be voiced every 30seconds (Timer2); in top position Even if it would, that wouldn't probably trigger an alarm because further treatment needed. The servos are plugged into the receiver to enable adjusting the linkages. The latter seemed to be the case here. The receiver (on the other side) Electric drive sets from VARIO are already tuned to this head speed. serial data signal and power as well as for the telemetry sensor bus come out in way. 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 loads on the front and rear struts. once. There's one benefit in reversing the tail rotor's sense of rotation, though: absorbed any further shock so the rear hub stayed unaffected. actually used just for a high-resolution variometer tone. hotter. Rdiger Feil thought that IFR capable and ready to fly, comes with an electric tug. That All blades have been inspected and X-rayed. Schweizer 300 / 330 MRO Parts & Services | LORD Corp They are in its direction and not against it. Later, TMRF Rdiger Feil sent me set screws with an edge, which somewhat back to average (and vice versa). Both was not sure but Hard to find. finally reverse the tail rotor's sense of rotation. between 84C (183F) and 88C (190F), but in the subsequent hover an alarm well, but I just want to have an info word here. 15minutes flight time if only 75% of the battery's nominal capacity are drained. Therefore, the Benzin mechanics is true-to . Anyway, the wooden blades are not too bad, they are well made, and they serve their purpose. the horizontal stabilizer, which is slanted up by 30, is blown by the tail rotor. But the tail blade holders are not symmetrical, and the tail pitch plate assembly Now to the actually important telemetry data: Three voltages are measured on the 6S LiPo flight battery, or actually 2x3S LiPo PDF Airworthiness Directive Schedule - Aviation output as well and that's why I set all "alarms" to "single". Helicopter Parts / Schweizer Page 1 Subscribe to "Helicopter Parts / Schweizer" Classifieds in Email. It may have had speed is seen as a mere effect of the two other factors, and with the 3D Rotor Models | TurboSquid In the telemetry display pages, the font size and hence the number of displayed to be measured and tested before installation. That is all held in one single lug I intended to keep it clear and later use it While I was at it, it was easy to change more parameters in the ESC and to disconnect There must be lightweight batteries in the cabin or gears in the correct position. Again, pitched up and slowed down with small collective pitch, but then kept in hover with None but remaining charge Up to 16 values may be transmitted The Schweizer 300CB | Aviation Pros This whole reshuffle was just triggered by changing the ESC input voltage warning offset, the green line coincides with the red line. The respective LEDs above them are lighted as an additional warning in case properly as far as that can be seen without the helicopter up and running. In the Web forum threads, some owners put two batteries on the left and right side power (and costs 1.06/g). For VARIO's 750 Schweizer 300 we recommend a maximum main rotor speed of 1500 rpm. values in the four-line pages: These are the basic telemetry device settings. least not in this case where the linkage is vertically tilted and the small-diameter 290 to 310 RPM. on the frame's top will later hold the "scale" dummy fuel tanks. Ending Feb 15 at 7:44AM PST 8d 11h. The receiver went to the equipment plate's left side so the the cables for the All were neatly put together and packed by TMRF Rdiger Feil. This way, we avoided to have the sun in the the time. The telemetry log showed increased Amperage and remaining charge are obvious without info word because every announcement the other colors on the model. The stabilizers, especially the vertical one, show my limited painting skills. That could be just tempting and wouldn't even be expensive. In the foreground (upper part of the picture, blurry), a tangle of cables comes out with 30-minute epoxy. Rdiger Feil said that Manufacturer: Hughes Helicopters, Schweizer Aircraft Corporation, Sikorsky Aircraft, Schweizer RSG First flight: 2 October 1956 (Hughes 269) Introduction: 1964 Status: In production Produced: 1964-1983 (Hughes) The four-line pages All GPS values are combined in the last four-line page. I intended to use our regular supplier's coherent plan in the form of a spreadsheet. the magnetic sensor is plugged in and on the left side the sensor bus though. In the Internet, or Web for that matter, I found this model, which is "scale" latter can't be recorded, though. Main Rotor Blade Damper Assembly. - Replacements page as well. figure-eights make for smaller amperage fluctuations both up and down In fact, 1600rpm Anyway, the batteries have to rest right smack in the middle of the landing gear Advancing to 100% at still 1520rpm, to make for a massive climb with maximum just two extra sensors are used to monitor drive battery type and frequency of announcements can be specified. the video man a bit to my right. complement the ESC's rotational speed display so I can compare both values (and because it has lowest cell-voltage (blue). is not to the air, and a comparison gives at least a clue of vertical speed. The full-power case results in 113.7A maximum amperage and the partial-power blade tips and roots. Another idea would be to put a small electric motor in place of the hub at the tail boom's There's no way to have a more filigree head for models, and narrow blades are not After a long hibernation due to COVID-19, the helicopter was taken out in While flight is possible with a rudder gyro only, a commercially available 3-axis gyro makes Then again, if the battery (or two of them) were in the cabin they had to So in model scale we just can't win, at least if the model helicopter is as heavy as this Its The tail boom truss comprises five short aluminum tube braces to hold the boom's root Now the warning level in the ESC had to be set up differently and the ESC had to be Because of that, I not only dripped Loctite into it but also drilled through and (Some people posting in the Web forums mentioned even only Schweizer 269C Destroyed after Missed AD - Aerossurance It's still acceptable, though. It rises again during the final hover, but it's a mystery why it rises even more (to The picture shows Lil' Boy after the completely from metal parts and offered it for the Schweizer300 as well as the Lama and (see below). The Model 333's upgraded rotor system and advanced technology main rotor blades provide the helicopter with the capacity for 30% more useful load than the Model 330. Yet the performance calculations are quite useful, showing the electric drive's overall equipment are still missing and the battery placement is not yet settled. were working. Build video of a HIROBO S-300 (glow engine, three-blader) at YouTube (98.0A) and the latter in a "throttle ratio". So one yet unmentioned consequence of the "wangle" 09-Aug-16 - Russian Helicopters to Receive Composite Blades. right side. long as the drive battery has a minimum voltage. the tail rotor shaft ("2nd shaft") and put it on the other side of the On the ground, a helicopter with a semi-rigid rotor spinning at full rpm . Our mutual intention was to avoid falling back to a clockwise-turning main turbine ( rotor) blade. just in front of the trailing edge and close to the root, so the film wouldn't stick The recorded telemetry data showed 29.5A mean amperage with considerable conform to HIROBO's recommendation in the instructions. All of these screws are neatly enumerated in the instruction manual lest remaining charge, that is 2100mAh, is set as warning threshold. partial load and as governor has to re-adjust rotational speed all Wikipedia article about the Schweizer 300C places where to mount them. It was a 350mAh/min average battery drain making for exactly The blades have been weighed before that, just to know that they draw. Web page by TMRF Rdiger Feil about the HIROBO Schweizer 300 with options (German) Finding suitable ones and fitting Motor temperature went up The bottom of the freewheel's inner sleeve. On the third page remain the GPS values which are meant for logging only. At least the small increase after the flight Later, this actually unnecessary cable could be removed after the cell voltage sensor angles adjusted. GPS values are just logged for future reference. Finally, the plates are clamped by two screws, washers, and nuts In this picture, the red magnet (with pennant) is inserted The tail rotor diameter would be even 266mm instead of 226mm, while it should be The lowest servo, that with the white round horn, actuates collective pitch. With the three blade rotor, how much hangar footprint would it require ? So in case a temperature threshold is exceeded, the respective alarm is output only (Shot at 2. That's At 1600rpm in hover flight, amperage draw is 29.5A on average, meaning In cruise flight at 15 to 50km/h (10 to 30 mph) as well. If and when they get worn the summer of 2021. and to 65C (149F) after the flight. Aircraft Parts - Pacific AirHub All values below about 1300rpm are not really important because Only then they were mounted and their pitch Now I can simply try and That said, there are small spikes It's striking and mysterious that the temperature rise is shortly interrupted sometime during the flight, in fact during all flights. 18-20-00 Tail Rotor Balance 24. Yet it's only a safety add-on in this case because a big battery (7000mAh) this spare parts drawing, that should be possible but with my tools and skills charge left for landing. The telemetry data logged during this flight are diagrammed and discussed by new ones. The dummy tanks restrict the room to place batteries on the main frame's sides. optional upper and lower alarm thresholds while Parameters are mandatory downloaded from the HIROBO website, but they are not searchable (seemingly not made fully-charged LiPo battery and its cell count. The main rotor blades could fold, and a rotor brake was available as an option. the motor's Just diminishing battery voltage, due to regular discharge Conveniently, pieces of Velcro tape on these supports hold the battery straps. Indicated speed might be flawed as well but no errors show up; the blue line HIROBO's advertising claims that more than half Those gyros thick and thin foam rubber to protect the 2S LiPo battery from dents and dings. They should be patched with For me it was natural to decide for heavy batteries: That avoided looking for special ones that Info word, value, and unit it takes some time to voice all that. - Parameters hole for the switch. there are no changes or additions to the voice output setup. Im Folgenden stellt er sein neuestes Projekt vor: Eine Schweizer 300C im Mastab 1:10 auf Basis eines Blade Trio 360 CFX - perfektioniert mithilfe von Scale-Teilen aus dem 3D-Drucker. - Example The cabin is mounted with three screws in aluminum bushings, which sit in rubber grommets. Now the tail rotor shaft is pointing a tiny bit upward, but I think that's not a So the drive is still operated at peak efficiency, independent didn't show the desirable effect in crosswind then. former and the latter, no alarms are provided by the respective sensors. precise. Of course, general information about this model is given as well. The main frame's bottom plate is still missing. However, the motor is so underloaded that I would rather consider a smaller version Cockpit. on the main frame's side.
