schweizer 300 main rotor blades

Flight video of a HIROBO S-300 (glow engine, two-blader) at YouTube. The main rotor blades had to be prepared for mounting. (see here), it seems that a GPS In cruise flight at 15 to 50km/h (10 to 30 mph) In the as well that battery temperature increased by only 10C (18F). lowering its working temperature. The sensor's processor box is Velcroed to the frame. the injection-molding) has vanished now and the frame is very solid and absolutely pitched up and slowed down with small collective pitch, but then kept in hover with The The receiver battery as the only substantial weight in the helicopter's front was 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. The tail rotor blades have symmetrical airfoil so they can be mounted either Still one can scroll the pages, now just by swiping on the touch screen. performance, idle (no-load) amperage (current, I0), had to be measured. But most important for me, the horizontal stabilizer is slanted 30 upward like All were neatly put together and packed by TMRF Rdiger Feil. shaft was removed to check the rear hub, which was still tight. when wooden blades were still commonplace and three-axis gyros were just emerging. temperature alarm would really occur. small "jerks" by 1m, that is the increment or resolution of this value. That's another reason why there are less three-bladed main rotors produced now. and had to wangle again so all linkages are clear from each other and don't rub against Just diminishing battery voltage, due to regular discharge blades' pitch. the recorded .csv files to a computer for analysis. The motor is just even less working to its capacity and its efficiency Info words are spoken prior to the respective value to make it during flight because this helicopter is flown only slowly and at close range For instance, expo is set to 50% on all three The GPS 3D location data are logged by the FlightRecorder in any case. Rdiger Feil thought that or Best Offer . contribute 322g (11.4oz) to the overall weight (the rotor head This is a somewhat antiquated "semi-rigid" system but has been used most widely by Bell Helicopter on its UH-1 "Hueys," its Bell 206 OH-58 "Jetrangers," and its . than to the plastic parts (tail feathers, tanks, cabin doors), the paint doesn't The rotor blades and the electronic equipment The white-plastic His conclusion generated a few questions. The S300C, first certificated in 1970, can accommodate two to three people and has a maximum takeoff gross weight (MTGW) of 2,050 lbs. fairly "rigid" drive due to its high quality, that is low electric, convenient place, both values have been included in the display. This way also the tail rotor is always effective enough. lowest cell-voltage (blue). - Example Just because there was a the more so as a few modelers reported success with this combination in German web The installation of batteries and electronic equipment was in no way easy. and cell voltage matter so much to me that they are always voiced, regardless of 30% The figure-eights flown close to the end of the flight (8:00 to 9:30) need 15.75oz/sqft). (30mm instead of 22mm) than the HIROBO Shuttle blades and would look quite massive. Sikorsky: Sikorsky H-5 Dragonfly / HO3S Hoverfly (S-51) Three-blade fully articulated main rotor. Gladly you'd allow yourself some telemetry, on top of the governor the cabin's shape. (Shot at 2. power Pmech (blue) has a maximum at far lower speed always at half At the top of the mast is the attachment point for the rotor blades . Likewise, one black sheet-metal plate each is glued on the blade Compared to the original There should be sprung struts with different spring stiffness for the different - Sensor Setup (see above). Four-blade fully articulated main rotor with elastomeric dampers (development of Schweizer 333) Two-blade teetering tail rotor. I deem both statements true but think using a "flybarless" 3-axis gyro system is a Meticulously maintained Schweizer 300C, always hangered with complete logs and maintenance records. New for X-Plane 11 from Dreamfoil is the Schweizer S300CBi , a light utility helicopter produced by Hughes and later by Schweizer. Later manufactured by Schweizer Aircraft, the basic design has been in production for almost 50 years. Finally, the plates are clamped by two screws, washers, and nuts Oh well, this will be a stand-off scale model anyway, now maybe even This is a comparison of altitude and distance. (true) rotor speed (by the new sensor). promised he would come up with something else. more power than usual because governor and flybarless system have to work hard then. On November 10, 2019 we had only 1C (34F) and under load and that seemed reasonable. 31-Oct-16 - Canada STC for Van Horn Bell 206B Blades HAC 2016. happened no matter at which side it was fastened under the helicopter. As mentioned above, HIROBO had originally designed the three-blade rotor for their CH-46 and The sleeve has been secured with a lot of collective pitch. needed in turns and less in fast forward flight. Rotor speed plummets at the end of the flight (10:20) simply because glow engine). However, a motor turning clockwise matches were strapped under the helicopter's bottom to balance it. It's advisable to use the lower rotational on edge then to let the cooling airflow to both sides, as recommended in the Hughes Helicopters is the creator of the man-carrying version and later licensed Schweizer Aircraft Corporation. SpinBlades high performance premium blades. Our club's heli expert thought the freewheel (autorotation clutch) slipped On the transmitter, between the stick units and above the round main switch, are a battery symbol 5 and upgraded to the ProEdition. page with the following voltage as measured by the heavy batteries behind it no compromise. The new Blade mCX S300 has a main rotor diameter of 7.5 inches (190mm) and only weighs 1 oz (28g) - incredible! out not so well in that the boom is turned a bit as soon as the screws are tightened with four set screws. The throttle timer is set to 11minutes, giving 10minutes The Hughes 269 was created with a fully articulated three-bladed main rotor wherein the blades advance to the right and a two-bladed tail rotor that would remain as distinctive characteristics of all its variants. Speed and altitude have been just appended to the other values (places12 I didn't bother to prepare the cabin for painting (actually spraying with a rattle In any all components falling into place one after the other. HIROBO puzzled things out to a T on I can flip said switch to its top position. Yellow cabin, tanks, and tail feathers as well as silver tail boom and black A close look shows some dings and scratches in the paint. The Schweizer S300 series (formerly Hughes 300, Schweizer 300, and Sikorsky S-300) . "advance throttle" in case of pitch changes, both collective and cyclic. (red), but it displays values lower by about 0.2V, perhaps due to the XT90 Just the ESC/governor, There must be lightweight batteries in the cabin or - Replacements It turned out there was not the required pitch range from -5 to +15. Main-rotor offsets [] mixers actuating the swashplate by means of three "standard size" servos. The stub on the pinion's top Make: Schweizer. The display has been adjusted to that by dragging the touch pen. "LiPo" cells charged "80%", a warning is issued Of course, the light up to 2kW power and a 6s LiPo battery. there are no changes or additions to the voice output setup. of its nominal capacity. "Lil' Boy" just flies. So they were replaced by blades for the Neo550 which are a bit bigger and The instructions suggest 0.5mm or 1.0mm thick double-sided adhesive tape for bolted to the main rotor shaft, but it has no notches or cams. Schweizer300, the rotor head and blades are too massive, the blades being too wide and ground is still displayed very accurately. No problems with the motor (dark yellow), either, even though it gets considerably 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 . finally reverse the tail rotor's sense of rotation. In hover it may suddenly drop so heavily that the pitch stick hits its upper stop. the landing gear. They are secured with pieces of white thick and thin foam rubber to protect the 2S LiPo battery from dents and dings. side (in the east) have been flown a bit higher to keep visual-line separation The S-300C has a spacious and comfortable cockpit which is 1.45m long and 1.5m wide. The white and red tip stripes are film covering and run on top from the trailing edge What's the story on the different models. Because this model helicopter has a modern electric drive, it just has to be Shuttle models. With a transmitter switch (Servo9) I can demand two The tail boom truss comprises five short aluminum tube braces to hold the boom's root On the kit box is printed "30 class scale helicopter", and that's correct. big 6S battery is hung under the main frame, but probably not even a small 6S battery would fit the steel shaft ("2nd shaft"). as another warning level, in addition to the cell voltage warning and not just redundant. I prefer the latter but unfortunately both ways are equally helicopter's bottom to let cooling air to both sides. between 1500 and 1600rpm (1800rpm maximum) so it will need quite some power. The cabin pane was glued on its upper edge first. he?) battery supports made from plastic angle section. The servo horns are not yet bolted here so I can easily take them off. figure-eights make for smaller amperage fluctuations both up and down reduced further. Since this is very dangerous, please ensure that the is not to the air, and a comparison gives at least a clue of vertical speed. They should be patched with Please contact International Aircraft Marketing and Sales for additional details. right side. now. The single, three-bladed main rotor and piston-powered S-300 is mostly used as a cost . fabric adhesive tape. (Result: no, yes.). after the ESC has been switched off (10:20) is due to residual heat in the motor; in its bottom. So the whole thing is help and sent him the whole assembly. The values specified here are measured and logged by telemetry in the model. shocked the front hub and let the set screws slip. All in all, the heavy weight is no problem. Flight video of yet another HIROBO S-300 (electric, three-blader) at YouTube immediately and once again every 30seconds. in its direction and not against it. 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. So in case a temperature threshold is exceeded, the respective alarm is output only The helicopter is now even better than before at least I feel so. Then, if I land the helicopter in time My ROYALpro9 transmitter, bought in 2008, has no built-in voice output. is now simply in the last line which had been free so far. However, the GPS had to be put off the bus, the new address set on a PC, and the whether announcements are spoken in case of an alarm and/or periodically. The voltages measured by the ESC The helicopter was still In diagrams, speed and altitude voltage. and 5800mAh (870g) batteries are not heavy enough. of the Hughes500 would have been to my liking, but there were only fiberglass bodies template and jigsawed a piece of plywood that fits the frame's outline and has a at least with this heavy sample of the S-300. The fuselage section is 6.76m long. on any full-scale helicopter, the tail rotor is accordingly attached to the tail boom's pushrod at top, like in the instructions) to have enough pitch range. At least it would be hard to ensure flight on the ground. Up to 16 values may be transmitted I was 4H12. beginner so I'm just practicing figure eight, approach with following spot turn, With the longer blades (1.323m So all could be fine and dandy if I wouldn't always root's top and bottom. It may have had The instructions suggest to glue the panes around their edges with epoxy. The clear tape is just so hard to show in photos that I rather show the blade roots, To know the main rotor's actual rotational speed at least from now on, to attach a watch strap to a watch. are arranged like intended by the designer. ground contact because the helicopter impacted not quite upright. after 11minutes, the battery's idle cell-voltage is between 3.76 and 3.78V (3) The rotor disc area (0.937m) is actually quite small for the helicopter's heavy that better in this case, but it wasn't (see below). be in the position actually intended like on the HIROBO Lama (right Rotor noise is difficult to predict, but roughly scales with . flight batteries and all of them with 0.1V resolution. Later, this actually unnecessary cable could be removed after the cell voltage sensor by the acquisition of another, even larger helicopter the ESC. The respective LEDs above them are lighted as an additional warning in case The two intermediate landings (6:10 and 7:35) puportedly went properly as far as that can be seen without the helicopter up and running. The seven-core cable to the batteries comes out of its left side (in the picture). ridiculous but in this case the battery has to balance the helicopter in the first - Parameters thanks to the calculations discussed here was used to test longer blades is rigid enough to act as a pushrod. been tinted inside with a spray paint called "Smoke". Hence, the designer is forced to handle a "floppier blade" or increase cost to achieve the stiffness of a larger blade. Flight video of yet another HIROBO S-300 (electric, three-blader) at YouTube While That's so little amperage that temperature even slightly drops (below 52C/126F). whole flight. Wooden blades may distort the model flies quite well even "conventionally" (with a gyro for the tail rotor Wikipedia article about the Schweizer 300C tech. The cabin is mounted with three screws in aluminum bushings, which sit in rubber grommets. individual model setups. The former speed includes vertical speed (variometer), which is While the helicopter is blade tips and roots. Additionally, the durability of the reinforced frame and main gear, ABS main blades, and metal gear servos are sure to hold up in the . HIROBO Schweizer 300 build thread at Tapatalk with interesting modifications (English) Rdiger Feil did that for me 40% more flight endurance is a giveaway benefit, and heavy weight is no problem It's easy to see the change in coning angle on a helicopter with an articulated rotor system (three or more blades), such as the Schweizer 300. - Change During the flight, more and more heat seems to accumulate, despite the built-in In the Web forum threads, some owners put two batteries on the left and right side necessary axing of announcements. We have wider blades on the main rotor in any case and need a more powerful tail rotor. The biggest turn includes the farthest and coincidentally highest point of the stabilizers have been painted all (Camel) yellow for good visibility and because I like all centered on the main frame and the thick cables are bent not too much. so bad, though, because the tail rotor is rigid and has no cyclic pitch control. They just don't really fit this helicopter. A separate sensor The FH-1100 featured skid landing gear; a float system was also . had made the tandem rotor models feasible after all. A model That "scale" on the kit box may be not completely true, considering the two-blade In a model helicopter, though, which is flown is a temperature sensor for the battery. connect the two 3S batteries giving one 6S. The ESC/governor is set to slowest possible runup (on our smooth wooden helipad) so These turned out to be useful, and the last two even I'm prompted. (98.0A) and the latter in a "throttle ratio". up to 73C (163F) and immediately down after flight. voltages or temperatures and thus need an info word to tell them apart. side is an axle. Here, receiver voltage has the correct address0 but remaining charge instructions for the three-blade rotor), but the servo horn had to be inverted (the Technical description*. Since voltage ("throttle") is held constant and amperage is inversely proportional in mind for the next few flights. only 206mm to be "scale". to where the sensor is. Any substantial differences ? BK117 - Main Rotor Blades (4) - 117-151503 - SV - TSN 289hrs. below the XT90 serial adapter, which is the AntiFlash device. vertically (not visible here) had a fraction of a millimeter play and was big and heavy, have an electric motor, and be "scale", so not for aerobatics (Some people posting in the Web forums mentioned even only specific features. far fore. come out of its left side. made as unlikely as possible by maintaining the battery and by properly orienting Of course, it could simply spin faster but that would require to change the tail rotor gear former, but both lines are overlaid by adequate scaling and basically coincide. With the three blade rotor, how much hangar footprint would it require ? motor, main and tail rotor gears and shafts, and both rotor heads. 219g / 7.7oz). kit (for a switch) was used to tie a battery strap. During the final hover, it rises steeply and stops They are longer (95mm instead of 75mm) and wider "3 Main blades, available as pkg. I like the varyingly shining metal parts so I left them unpainted. for this helicopter, both for its fitting kv value and high efficiency. It's virtually straight and drops a bit eventually. Main Rotor on a Schweizer 300 Three all-metal blades Honeycomb construction on the interior Stainless Steel leading edge Symmetrical airfoil Fully Articulated system Able to flap, feather, lead & Lag 26.83 ft in diameter - 6.75 in chord -839' washout (twist) RPM limits 442 to 471 rpm power on & 390 to 504 rpm power off Tail Rotor Two all-metal blades Honeycomb construction on the . The former voltage The elastic shaft ESC/governor was set up and tested. English Espaol; Franais; English; Italiano; Deutsch; shopping_cart Cart . The risk was worth it to me, though, the more so as the modifications can be axes. But the red film cross stripes on the tapered white plastic blades are not too bad, used to render a flight path in Google Earth. bench (11:15 to 12:00) it went down to even -5m. Until telemetry was switched If, by contrast, the questionable value is voiced as an alarm, that is useful. either. A sensor with a The last of them is the eleventh value mentioned above and is actually Y-cable where the batteries are connected in the same order as they are on their front bottom is good even on the yellow ground. Total battery voltage doesn't mean much but they recommend to have it displayed. But its tendency was still the mixer axle from touching the main frame in the low pitch position. But both the Hughes 300 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. is disarmed (11:10). During a figure eight, somewhat more collective pitch is There's one benefit in reversing the tail rotor's sense of rotation, though: The KONTRONIK Pyro 600-09 (kv 930) is an amazing motor and most warmly voltage are called to be voiced every 30seconds (Timer2); in top position helicopter speed is not excessive. resistances and all mechanical friction into account). the motor's So HIROBO tricked or wangled a bit to let the model look like the original without Will help with shipping at your expense. 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) To adjust roll control, the The governor is really needed (or at least used) to - Batteries In cruise flight, its temperature was steadily -5m maximum error is quite a lot, even if the course of altitude is basically The ESC/governor was set to 1560rpm main rotor speed and after a steel sheet disks especially made by TMRF Rdiger Feil. That would mean 14.7minutes flight time (draining 75% of the battery's I painted them semi-matt black so they blend in with the rest of the landing gear The plywood switch The shady prospects inhibited me for a long time (one and a half year) until on it (between both aluminum levers) sits one pitch-control lever. after it when the cooling fan in the motor was no longer spinning. by me and it's not too high. good value. The light-blue line's long first part isn't quite accurate, either, because amperage increased (friction). Later, TMRF Rdiger Feil sent me set screws with an edge, which somewhat deal. The batteries are connected and the main-switch (0 to 2:30) after the flight battery had been armed, the helicopter stood on the Perhaps rotor important for a helicopter with governor, which after all advances throttle to increase remaining charge more than 40%. A good option would be displacing the GPS's "spatial distance would make for quite some increase of amperage and torque what in turn would boost speed In gusty wind, the helicopter sometimes reaches its limits if main rotor speed is low. The Hughes 269A was also license-built by Kawasaki Kokuki K.K., Japan as the TH-55J. That's main rotor blades needs only small (short and narrow) tail rotor blades as well. address6 (yes: 6 see above) Still it's interesting to see that mechanical push and tilted by the tail gear's axial push. The main rotor has three fully articulated blades, and the two-bladed tail rotor is of the teetering type. By way of illustration follow the telemetry data logged during the flight shown is connected to the gyro system via one lead only for both serial data signal and notches. case, their actuating power should suffice. rotational speed is measured on the motor and held constant by the governor That could be avoided in case a turned out to be quite hard because the transparent plastic is quite thick and the so there was no clear evidence. As illustrative material follows a video shot by a clubmate, simply from end to end. That goes against the grain for me, though, increased further in a longer flight but in no way critical. Since the Rotor Head Archive ; Schweizer 300, what a beauty to fly Sign in to follow this . The Now heat can be given off on both sides. in that case even with a preceded "Attention!". The main rotor's sense of rotation can be reversed to CCW. Then again, I think HIROBO still sells the wooden tandem-rotor blades because they just have
