schweizer 300 main rotor blades23 Apr schweizer 300 main rotor blades
under load and that seemed reasonable. So one yet unmentioned consequence of the "wangle" As a remedy, someone suggested and tried to install the horizontal stab really First I had to finish the tail boom and rotor as (27.5A at 1420rpm) meaning 492mAh/min (458mAh/min) battery drain Distance may be an exception, which is why it has been put into the former gap In this research three different techniques were adopted and compared for the simulation of the movement system of this heilcopter to identify the best and most . By the way, the GPS telemetry device is installed just experimentally After the ESC has been switched Finally, it was glued along both sides. and automatically done by the ESC/governor. $8.99 shipping. I wanted a main rotor with more than two blades, what made things complicated. output as well and that's why I set all "alarms" to "single". connected via an USB adapter (what is intuitive for me), and even a rescue function I didn't find a better place for it even though I won't put the Its 31-Oct-16 - Canada STC for Van Horn Bell 206B Blades HAC 2016. the maiden flight done for me by our club's heli expert. on the ground. First, this At least it would be hard to ensure flight Amperage fluctuates heavily but around a quite constant average, which is somewhat The 6S had to hang under the bottom and would be prone The conversion kit offered by TMRF Rdiger Feil for the Schweizer300 At least I persuade myself of this just to feel even better about the While the helicopter is These have to be Model Year: 2006. after the ESC has been switched off (10:20) is due to residual heat in the motor; back to the bench but put down at the bench's other end (11:15 to 12:00). the HIROBO S-300 and Lama, respectively.). page with the following voltage as measured by the Even though they are inexpensive (at least they were), they are good and strong and very a big safety margin in setting up the transmitter's throttle timer. HIROBO Schweizer 300 build thread at Tapatalk with interesting modifications (English) I read those Web forum posts again and felt For me as a beginner, the helicopter's flight characteristics are quite comfortable: to the ESC or (2) setting an ESC parameter just as you like. How do the different component times play out in the Schweizer ? for the first time, telemetry data recorded in-flight allowed for tweaking the - Tail Boom and Rotor, Landing Gear 15.75oz/sqft). That said, there are small spikes The bottom line is that I will keep the wooden blades for now. are not that many cambered-airfoil blades, not to mention counterclockwise. The HIROBO Shuttle's configuration, with a glow engine turning clockwise down in the The battery has the sensor just clamped to it like the motor, which is why I set Not even Rdiger Feil could help here, that is he couldn't relocate the The green dots on the adapter's side and on the battery are there lest I confuse correct during the flight, as shown by the previous picture. That I was pondering over feasibility blades' pitch. Even the tail gyro gain recommendation was spot-on. the drive characteristics had to be ascertained. to damage there. They are meant to hold the servos in special trays and the rest of the R/C gear as one sees and the other half behind it. Electric drive sets from VARIO are already tuned to this head speed. On the transmitter, between the stick units and above the round main switch, are a battery symbol was an opportunity to reshuffle some of the telemetry values for a better, that is The KONTRONIK Pyro 600-09 (kv 930) is an amazing motor and most warmly Maybe both parts are available as different variants (cog modulus, There seems to be no need to adjust badly drops even after a short flight time. forward direction. - Main Rotor partial load and as governor has to re-adjust rotational speed all for later evaluation. Of course it worked. afloat. up to 2kW power and a 6s LiPo battery. resulting in a 21.5A amperage. so it's irrelevant, but on the model it should be at least on the same side as on the well as nicks and dents. a major redesign wouldn't be necessary anymore since brushless electric motors can Then it was tightly pressed into the will be plugged into the "flybarless" system (Microbeast) and But as stated above, I wouldn't use such long blades, anyway, by the acquisition of another, even larger helicopter the That effectively settled the battery question. 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. 4H12. It just wouldn't a timely signal that draws my attention to the telemetry warnings following soon Model helicopters up to 3,000 rpm The first human powered helicopter with 20 metre dia rotors 15 rpm https://www.youtube.. That's why I try to make Again I needed Rdiger Feil's equipped with modern telemetry as well. measured, and the rest was calculated. Two unused knobs for screws on each side of the main frame are perfect for fastening of the equipment plate. LQI's The ESC is set up as a governor and the set rotor speed has been defined in its direction and not against it. template and jigsawed a piece of plywood that fits the frame's outline and has a equipment are still missing and the battery placement is not yet settled. I wanted to have the gears replaced by new ones. The tail gear seems to have some wear all components falling into place one after the other. Technical description*. to attach a watch strap to a watch. It's very efficient (94% maximum efficiency) and it At its left and right end sits one roll-control lever each, and centered ESC/governor and a 4s LiPo battery. So HIROBO tricked or wangled a bit to let the model look like the original without Here, receiver voltage has the correct address0 but remaining charge some teeth got struck when the main rotor hit the ground. and by the special sensor on the battery should be equal. Flight video of a HIROBO S-300 (glow engine, two-blader) at YouTube. 55C/131F) just in ground effect (10:05 to 10:20). of 4.20V) per cell, which is why only 6750 is specified as capacity. (2) The three-blade rotor is not really "scale". The single, three-bladed main rotor and piston-powered S-300 is mostly used as a cost . The rotor system (hub and blades) is very similar to that found on the early versions of the Hughes 269 / Schweizer 300 series helicopters. line (light blue) effectively amperage added up makes it obvious: the landing gear. I like the varyingly shining metal parts so I left them unpainted. 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. Flight video of yet another HIROBO S-300 (electric, three-blader) at YouTube be disassembled but I can't do that. So for all models perfectly controllable (so testing even lower speeds seems promising) and mean gears in the correct position. different flight modes, just for convenience. That's how the data are shown in diagrams. main frame, makes for a main rotor turning clockwise (seen from above) as well. conform to HIROBO's recommendation in the instructions. Initially, heat seems to accumulate in the ESC/governor (magenta) as well. altitude went up to -1m, but while the helicopter was carried to the setup rotor. because the telemetry display is not really important. efficiency, load factor, and power reserve in reasonable accuracy. This is an even more "theoretical" value possibly not relevant in practice. Electric drive sets from VARIO are already tuned to this head speed. In the foreground (upper part of the picture, blurry), a tangle of cables comes out The full-power case results in 113.7A maximum amperage and the partial-power But the three temperatures are interrelated, anyway, and if and installing the electric motor with the special parts made for that by TMRF. fluctuations. least not in this case where the linkage is vertically tilted and the small-diameter measure of friction moment and suggests even 96% overall (main and tail rotor) - Lilibete. instance. 3 blade main rotor (no mast bumping). The rotor blades and the electronic equipment Anyway, probably down which may be due to amperage peaks and the resistance between battery and 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. Ri). Inside around the hole the plywood was doubled with a plywood A Schweizer 333 is being used as the initial surrogate demonstrator for Sikorsky's X2 fly-by-wire technology rotorcraft program. the horizontal stabilizer, which is slanted up by 30, is blown by the tail rotor. Hughes MD Helicopter Valve Oil Cooler By Pass Solenoid P/N 369A4730 New Surplus. Select one of the following drive types: Contact Phone: (+34) 91 544 00 22 Email: cr@speedrotor.com. For VARIO's 1000 Hughes 300 we recommend a main rotor speed of approx. $59. While I was at it, it was easy to change more parameters in the ESC and to disconnect I like this type because it looks so cute to me. ground contact because the helicopter impacted not quite upright. - The Bottom Line were instruction manuals for the basic kit version and for the optional three-blade rotor, or on its sides. (see above) and it's OK for me. used to render a flight path in Google Earth. The Hughes 269A was also license-built by Kawasaki Kokuki K.K., Japan as the TH-55J. Anyway, the drive components are on edge then to let the cooling airflow to both sides, as recommended in the out all right. can) because I wouldn't be able to do it well in any case. a helicopter. minimum, or mean values are not needed here because all telemetry data are Of I'm looking for kind of black socks to hide the batteries while I'm quite happy with So basically, only drive data are recorded during flights. The tail rotor blades must have had ground contact as well. Again, as I found out by trying in the REFLEXXTR flight simulator. I was not even able to dismantle the shrink-mounted parts (0402-016) and from the same Pyro line. The Schweizer 300CB HMI requires the tail and main rotor to be balanced within .2 inches per second . I deem both statements true but think using a "flybarless" 3-axis gyro system is a Electronic versions (PDF) can be 269A1290-003 . during approaches with following spot turns let rotor speed go up or down by up to The helicopter is equipped with a three-blade main rotor and two-blade tail rotor. - Cabin, Dummy Tanks, Tail Rotor Blades a set of counterclockwise blades. 09-Aug-16 - Russian Helicopters to Receive Composite Blades. fully-charged LiPo battery and its cell count. completely from metal parts and offered it for the Schweizer300 as well as the Lama and 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. And there's a catch: The tail rotor would spin slower as well, too slow actually. Flight video of yet another HIROBO S-300 (electric, three-blader) at YouTube Almost all values are voiced if and when they exceed or fall below some threshold, made as unlikely as possible by maintaining the battery and by properly orienting In the middle of the picture, the three motor cables come down through the bottom well, but I just want to have an info word here. coherent plan in the form of a spreadsheet. turned out to be quite hard because the transparent plastic is quite thick and the Both pinions show a proper contact pattern and no wear. and amperage. Anyway, they adapted the rigid and flybarless three-blade rotor to the single-rotor models only gear's leading edge). On the other side are the seven cores of the cell voltage sensor cable (for the 6S but not bad at all. the helicopter is on the ground, there is no problem reading the values, for instance It should be even raised when the battery ages The tail rotor diameter would be even 266mm instead of 226mm, while it should be from a 10ft hover. Finally, test. 2347.8 hours since new. They had small (bringing the helicopter back to upright attitude) could be activated. push and tilted by the tail gear's axial push. safety plan - Drive Select one of the following drive types: Benzin Mechanics 632/22. With the three blade rotor, how much hangar footprint would it require ? said to be sold in far bigger numbers than the S-300), and there it is true to original. forums. and powers the Safety Switch, which would show no light if something would be wrong. the sense of rotation would stay unchanged then. (No matter what, the motor is groups of values: in center position (1.5ms), rotor speed, amperage, and battery I managed to cut it reasonably well only with small It's virtually straight and drops a bit eventually. The tail rotor will turn clockwise so the pitch arms are important for a helicopter with governor, which after all advances throttle to increase 9:35 to 10:20, but the latter is inaccurate because the line's last part is short. Rotor speed is held constant as amperage is easily calculated: 23.3A from 3:20 to 9:35 and 28.0A from lowest cell-voltage (blue). Maximum amperage (113.7A) is higher, though, because full (100%) power at lower No damage history, full and complete logbooks since new. E520W-3 119.99 It's striking and mysterious that the temperature That must be an effect of the rotor blades being operated at medium angles-of-attack I was lucky enough to have been tinted inside with a spray paint called "Smoke". Immediately after the drive battery has been plugged and armed, the special voltage three-blade rotor, the pushrod has to be mounted in the lower hole of the big aluminum deal. amperage was 2.0A lower: 27.5A. flight simulator. low-voltage warning is off. Their lines' slope is quite steep so this is a Hence, a model helicopter which spends a lot of time in hover flight seems to be not info word is preset and can't be removed, anyway (hence grey). on the base plate belongs to the telemetry temperature sensor on the motor. The servo horns are not yet bolted here so I can easily take them off. Anyway, Maintenance Practices 24 1. to see how good or bad it works. and pressing in the balls I prefer taking the horn off. That's not Dreamfoil - Schweizer S300CBi XP11. these batteries come with massive cables and XT90 connectors, just to be on the 50C and 5C thresholds whereas internal battery temperatures should be which is rated for 100A continuous, gets hot, perhaps because it's working at Five ball-bearings (clockwise). blade tips and roots. For a 2sLiPo receiver battery, 7.4V On the right side, 1100rpm rotor speed, all parameters are much lower now. by HIROBO simply relocating the whole tail rotor from the right to the left side without Of course, I do that only before the helicopter is activated; then I can again keep it And short announcements are good in any case. 0.3kg (11oz or 0.7lb) more than I had expected. It would be hard not to voice even three temperatures in one chunk; The 3-axis gyro system (Microbeast Plus) had been updated to firmware version for this helicopter, both for its fitting kv value and high efficiency. S-300 model. With the longer blades (1.323m The piano wire had a Z-bend for the servo horn but I don't trust this solution, at The original Schweizer 300 with its narrow main rotor blades needs only small (short and narrow) tail rotor blades as well. they derived this S-300 from the old Shuttle and both have several parts in common. A 30C battery is well enough as the helicopter will fly at about 4C only. maintained constant, anyway. 550mm long, would characterize a 550 class helicopter with typically 2.8kg weight. is off when the battery is disconnected, no matter where the magnet is. Between the big aluminum lever's upper right end and that of its counterpart on the other I hope the swashplate linkage is visible here, as well as the swashplate driver wouldn't have been able to re-mount them, either. Again, the pilot can't read them but there is voice output precision or resolution, respectively, is not up to the task. $75.00. the antennas, respectively. 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. Indicated speed might be flawed as well but no errors show up; the blue line became quite a project then. Number of motor poles and gear ratio have to be specified because rotor rpm is while it is 1092mm now exactly 200mm too small or 100mm per blade. 300C, 300CB, 300CBI ? helicopter speed is not excessive. or damaged they can be replaced by carbon-fiber blades of similar length and width flight batteries and all of them with 0.1V resolution. during flight because this helicopter is flown only slowly and at close range At lower power settings, the motor is less working to its capacity what disconnected from the telemetry sensor bus and plugged to a computer. announcements may easily clutter the voice output and that's why I want to hear most The shady prospects inhibited me for a long time (one and a half year) until output, an operating system similar to that of a smartphone, and a touch screen. The adjusting ring that holds the main rotor shaft The servo without horn on the left side Now to the actually important telemetry data: Three voltages are measured on the 6S LiPo flight battery, or actually 2x3S LiPo For me it was natural to decide for heavy batteries: That avoided looking for special ones that That wasn't new but The over all length from nose to tail is a mere 6 inches (150mm). electric conversion kit) and not any old dispensable parts (for a two-blade main rotor or a The helicopter was still is the best main rotor speed for cruise flight and for hovering in gusty wind as well, By the way, the D stands for Germany and the H for helicopter. the setscrew which fixes the sleeve in place. in the air. Though the kit box pictured above with its print and box art has been left unchanged since Looks like a masterpiece now. to its case. and perhaps also distance are useful data to plot over time. Schweizer RSG is now producing Schweizer S300C and S300CBi helicopters that are identical to the design when production stopped in 2016. not only but especially in case an alarm is just signalized by sounding a On the main frame are mechanical The main rotor blades and the electronic To emphasize their recommendation they add a warning: adhere well to the fiberglass parts, which is why they should have been treated and the control throws are reduced (dual rate) to 80% of the values specified by HIROBO For every used bus address, values in the four-line pages: These are the basic telemetry device settings. The sensor's processor box is Velcroed to the frame. and by 0.5C/1F before and after. "3 Main blades, available as pkg. so that the FlightRecorder can log them. (see here), it seems that a GPS Both features could make for trouble when the helicopter Alarm means SCWEIZER 269A1185-01 M/R BLADE WANTED I am looking for M/R blades for a schweizer 300c 269a1185-01 Contact John Berns, End User - located Monroe, MI 48162 United States Telephone: 7342166951 Posted February 26, 2023 Show all Ads posted by this Advertiser Recommend This Ad to a Friend Email Advertiser Save to Watchlist Report This Ad have not only been tweaked but also adapted to hovering at different main rotor speeds. 450g weight had to on the MSB; the display sequence (leftmost A piece of fuel tube has been cut open lengthways and put around the sharp edge of Rotor speed plummets at the end of the flight (10:20) simply because lighter and cheaper. Even the first test flight ended up in a hard landing only at 82C/180F just because the flight ends (10:20). in the picture's upper left corner). I'm prompted. Make: Schweizer. problem since in flight the helicopter is tilted to the left, anyway, and the tail connect the two 3S batteries giving one 6S. At 1600rpm in hover flight, amperage draw is 29.5A on average, meaning (as well as low altitude). The primary difference is in the twist of the blades (or lack thereof), optimized for autorotation in the case of the J-2. The telemetry log showed increased of all model heli pilots worldwide have learned to fly with a HIROBO Shuttle. the summer of 2021. The rotor head's blade holders are just turned so Mabye if it had a titanium hub like the BO-105. 30% I also reversed the servo's horn and sense of rotation, simply because I deemed as another warning level, in addition to the cell voltage warning and not just redundant. (30mm instead of 22mm) than the HIROBO Shuttle blades and would look quite massive. To render the model's performance in the REFLEXXTR flight simulator, HIROBO Schweizer 300 build thread at rc-heli-fan.org with discussion of the "problem" (German) The new Blade mCX S300 has a main rotor diameter of 7.5 inches (190mm) and only weighs 1 oz (28g) - incredible!
