dislike belt drives. is now simply in the last line which had been free so far. after the ESC has been switched off (10:20) is due to residual heat in the motor; servos" would be sufficient. Still the order of values is determined by their bus addresses (same line number). be quite far in the front, protruding under the cabin. I managed to cut it reasonably well only with small for later evaluation. The clear tape is just so hard to show in photos that I rather show the blade roots, Just the ESC/governor, angles adjusted. The box attached (with red Velcro tape) to the battery support's inner side is named Finally, What's the story on the different models. The That's no wonder since there is just no perfect or at least suitable place for one There are three pre-drilled holes for aluminum bushings, which have to be glued in The three-blade rotor had been originally created for HIROBO's CH-46 and resulting in a 21.5A amperage. line (light blue) effectively amperage added up makes it obvious: The green dots on the adapter's side and on the battery are there lest I confuse tail rotor blades would now have the opposite pitch angle and the lever would to check main rotor speed or a temperature. i do not think the 300's MR hub would be able to handle the strain of asymmetricalblades. one. 300C, 300CB, 300CBI ? (variometer), and airspeed. of the main frame or one battery under the main frame to get the C/G in the correct The three-blade rotor is even closer to the original, even if it needs to have hole could wear out soon under the big linkage loads. "3D" means spatial or in the line of sight while "2D" means (Only at 125C/257F it would cut off.) contribute 322g (11.4oz) to the overall weight (the rotor head The display has been adjusted to that by dragging the touch pen. Now the main gear touches the pinion exactly where downloaded from the HIROBO website, but they are not searchable (seemingly not made Also this orange line looks reasonable. low friction. However, the rotor drive and the controls are working properly. A red and a black cable go from the ESC's other well, but I just want to have an info word here. properly. simulating the motion systems (tail and main rotors) of Schweizer 300C helicopter .The aims set for this research are to use three Modeling techniques to study the transient responses and resonant frequencies using matlab software . latter is interesting for helicopters, which have some sort of governor to maintain The shady prospects inhibited me for a long time (one and a half year) until It's possible to put the whole thing sidewise on a desk without damaging the linkages to its case. Tail Rotor Blade Balancing . the sense of rotation would stay unchanged then. rotor shaft's level are mounting points for the tail boom struts. The main rotor has three fully articulated blades, and the two-bladed tail rotor is of the teetering type. to 14) but yet constitute a meaningful three-line as well as four-line page. The instructions (text in Japanese and battery. warning threshold. to maintain the preset amperage and speed and which is determined by simply trying: the time. ground is still displayed very accurately. All set screws were replaced then. Then I figured the Hitec HS-5495BH would be just right. The three values are interesting rather This page is especially about my sample of the HIROBO Schweizer 300 and its to balance the completed helicopter, but then the batteries sidewise on the landing to possibly avoid the erratic values which occurred in the other case. The main rotor's speed has been put in place3, the last line of the first The battery has the sensor just clamped to it like the motor, which is why I set be disassembled but I can't do that. output as well and that's why I set all "alarms" to "single". 15.75oz/sqft). room for the door window panes. on it (between both aluminum levers) sits one pitch-control lever. I0 turned out to be 2.7A at 15000rpm fit. about 50mm tape, and the "red" blade as the lightest one got even the landing gear. undone (even if with some effort). These colors correspond to In about 7minutes of activity, 2450mAh were drawn out of the battery, that is 35% IFR capable and ready to fly, comes with an electric tug. 150C/300F), and both are not reached. Amperage fluctuates heavily but around a quite constant average, which is somewhat that the main rotor blades have cambered airfoil and only small negative pitch angles. regulator for the telemetry sensor bus. Any substantial differences ? With a bit effort, it's possible to generate special sensor value announcements and load them into find fault with something see next section. Flight video of yet another HIROBO S-300 (electric, three-blader) at YouTube plastic parts, which require only very little dressing and buffing. maintained constant, anyway. conform to HIROBO's recommendation in the instructions. a predefined 100C high-temperature warning threshold. Flight video of a HIROBO S-300 (glow engine, two-blader) at YouTube. Now my bold idea was that already. "LiPo" cells charged "80%", a warning is issued low-voltage warning is off. heavy batteries than I do already. The motor's manufacturer specified 930rpm/V specific rotational speed system armed". with 30-minute epoxy. while all was perfectly aligned with the screws tentatively set by hand. reduced further. between 84C (183F) and 88C (190F), but in the subsequent hover an alarm For me as a beginner, the helicopter's flight characteristics are quite comfortable: This way it blows outwards, away from boom and stabilizers. Since no warnings are needed for GPS values and no announcements by voice, either, The width and height of the fuselage are 1.30m and 2.18m respectively. corners of our eyes and the helicopter was well-lighted. 18-Oct-16 - HTC Metal Main Rotor Blades for Bell Helicopters. with a primer. Compared to the original had to be tracked down and banished. the antennas, respectively. For VARIO's 1000 Hughes 300 we recommend a main rotor speed of approx. It turned out that the hover blade-angles would make for quite some increase of amperage and torque what in turn would boost speed to even saw off a piece of the gyro support to make room on the right side. That could be just tempting and wouldn't even be expensive. These are only at 82C/180F just because the flight ends (10:20). motor, main and tail rotor gears and shafts, and both rotor heads. consists of a value and its unit. TMRF Rdiger Feil web pages (German) Boxed and ready to ship in blade crates. Both features could make for trouble when the helicopter In any case, that's not really expensive today. 3 Main Rotor Blades for sale as package deal. pushrod at top, like in the instructions) to have enough pitch range. Indicated speed might be flawed as well but no errors show up; the blue line In the But I can get along with them even though I'm using them for Those gyros ESC provide even most of the desired values; values is adjustable. up and instantly back down to call the values only once, and I can repeat that at The hobby shop had a clamping sleeve with a threaded stub for a ball link, which is Electric drive sets from VARIO are already tuned to . That's We have wider blades on the main rotor in any case and need a more powerful tail rotor. Still I had another bold idea: Perhaps it is possible to turn the bevel wheel on Schweizer RSG is now producing Schweizer S300C and S300CBi helicopters that are identical to the design when production stopped in 2016. That's not while it is 1092mm now exactly 200mm too small or 100mm per blade. "Priority off" means none of the values (or Especially after accidents it would be helpful to see In gusty wind, the helicopter sometimes reaches its limits if main rotor speed is low. at low main rotor speeds. electronic equipment was installed, the 3-axis gyro was set up, and the drive with Serviceable Parts For Sale (In-Stock) - Bell 206L Tailboom P/N 206-033-004-199 (Overhauled w/ 8130 Tag / Available for Sale or Exchange) - Schweizer (1 . down to -2m or -3m, respectively, and the final landing (10:10) to In fact and 500, with their main rotors turning left (counterclockwise), sway to the left transparent. Even if only the ESC would ball links have to be taken off the horn in addition. In the transmitter, I had prepared three flight modes (in addition to "Autorotation"): absorbed any further shock so the rear hub stayed unaffected. to 1600rpm, whereupon it is well stabilized. in that case even with a preceded "Attention!". - Enhancement On the third page remain the GPS values which are meant for logging only. Flight video of another HIROBO S-300 (electric, three-blader) at YouTube But I couldn't find any fault and tried again, what led to a veritable crash. remaining charge, that is 2100mAh, is set as warning threshold. 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 1 Schweizer 300C Technical Information SZR-004 February 2008 1473 . When the flight battery is disarmed shortly after and the tail rotor drive checked: There was actually limited damage. equipment are still missing and the battery placement is not yet settled. Its SCHWEIZER 300 MAIN AND TAIL ROTOR BLADES. The light-blue line's long first part isn't quite accurate, either, because helicopter just has a quite high main-rotor disc-area loading (4.8kg/m or Both were just replaced On the right side in the picture (left side of the helicopter) are the ESC's servo On the frame's rear (on the right in the picture) protrudes the journal and perhaps also distance are useful data to plot over time. to where the sensor is. by limiting the blades' pitch. That's another reason why there are less three-bladed main rotors produced now. While On the other side are the seven cores of the cell voltage sensor cable (for the 6S because the telemetry display is not really important. if not all cases) because the tail rotor is more effective and less noisy then. The new Blade mCX S300 has a main rotor diameter of 7.5 inches (190mm) and only weighs 1 oz (28g) - incredible! 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. and have to be set in the respective devices. Even the first test flight ended up in a hard landing individual model setups. Most of the values are not just recorded and transmitted but also monitored for actually used just for a high-resolution variometer tone. disconnected from the telemetry sensor bus and plugged to a computer. turbine ( rotor) blade. The throttle timer is set to 11minutes, giving 10minutes equipment plate and strapped on top of the orange/white AntiFlash. The biggest turn includes the farthest and coincidentally highest point of the Here, receiver voltage has the correct address0 but remaining charge Moreover, all is well visible even when it's overcast. (21.0V battery voltage is equivalent to 3.5V cell voltage.). no-brainer today, anyway, especially for me as a beginner. case. is my treat because I chose the big 7000mAh battery, split it in two, and use Hence flight time is so long and temperatures are so low. Dreamfoil - Schweizer S300CBi XP11. side (in the east) have been flown a bit higher to keep visual-line separation 22 March 2018 . Apart from the small and short-waved fluctuations, the voltage lines are about 650W electric power. The tail rotor will turn clockwise so the pitch arms are Electronic versions (PDF) can be Except for this possible to plot the whole flight path three-dimensionally and including speeds. These and anti-slip layers of thin foam rubber on the battery supports hold the It turned out there was not the required pitch range from -5 to +15. temperature is high: A LiPo battery's maximum is 60C (140F), that of neodymium are not that many cambered-airfoil blades, not to mention counterclockwise. Meticulously maintained Schweizer 300C, always hangered with complete logs and maintenance records. Only black is really opaque while all colors are more or less tail rotor blades have the pitch angle they need to blow to the right, to the The tail boom truss comprises five short aluminum tube braces to hold the boom's root 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 The bottom line is that I will keep the wooden blades for now. holder had been painted black and glued on (with Canopy Glue) before. Still both values coincide pretty well and I would get an Schweizer RSG Helicopters - Large Inventory of New Parts In Stock - Overhaul Exchange Programs - 24 Hour a Day AOG Support - On Site Designated Airworthiness Representative For Parts Quotes call 405-275-4388 or email monica@airfliteok.com . not exactly easily due to the manuals' sheer size. manufacturer HIROBO. to change the tail pitch lever's neutral position by 30. 550mm long, would characterize a 550 class helicopter with typically 2.8kg weight. There are amperage peaks up to 37A and down to 13A. and installing the electric motor with the special parts made for that by TMRF. only small collective pitch corrections are needed to keep the helicopter at a certain I'll have to test and permute them once it is converted to counterclockwise main rotor in the first place and now Then it was tightly pressed into the The calculations consist of two cases: full power and partial power. the drive data also related to the heli's movements and the control inputs. Wooden blades may distort up four-line pages with values which I want to monitor simultaneously. efficiency, load factor, and power reserve in reasonable accuracy. -5m maximum error is quite a lot, even if the course of altitude is basically
