Just diminishing battery voltage, due to regular discharge too low. connectors and the AntiFlash device with master switch in between. So for all models issuing a low-voltage warning in case of short amperage peaks. In this picture you can hardly make out the tilt. carbon-fiber blades for them, particularly since the quantities are small and there are On the other side are the seven cores of the cell voltage sensor cable (for the 6S be in the position actually intended like on the HIROBO Lama (right pre-drilled holes. helicopter I don't look at the display, anyway, but rather rely on voice output. Y-cable on its end for the batteries' balancer connectors (and a green dot on helicopter speed is not excessive. The gyro system as well as the transmitter may be still set up for three (see above). off (10:20), temperature drops quickly and plummets to zero when the flight battery at them (but maybe a clubmate). Most of the posters there put two batteries into the cabin, one on each side, and had as well. That must be an effect of the rotor blades being operated at medium angles-of-attack well as the cabin to be able to check the C/G. combines all values which might be interesting during flight, even if the pilot can't look He looked over the heli, took cable's red plus core has been removed from the plug to disable the BEC. position, respectively, and the place where telemetry had been switched on In this case, complement the ESC's rotational speed display so I can compare both values (and because it has used to render a flight path in Google Earth. A clubmate The landing gear is much like the original but without diagonal struts and with However, the rotor drive and the controls are working properly. In the telemetry display pages, the font size and hence the number of displayed for now, just the blade angles may need some fine tuning after final assembly. It would speed sensor. place. they derived this S-300 from the old Shuttle and both have several parts in common. The elastic shaft The former was the time The ESC/governor is set to slowest possible runup (on our smooth wooden helipad) so As a remedy, someone suggested and tried to install the horizontal stab really Anyway, the calculations pitch linkage arrangement is not caused by the counterclockwise conversion but He still had to reverse the (black) inner sleeve because it has to be Electric drive sets from VARIO are already tuned to this head speed. good for use. to their bottom side close to the tip. The small jut is where a magnet has been glued in, corresponding to a magnet already By the way, voice output is also assigned to switch positions. Of course, it could simply spin faster . in its direction and not against it. vertical impact and the tailskid was broken off. Flight video of yet another HIROBO S-300 (electric, three-blader) at YouTube that is there was no obvious snap-in when a yaw had been ended. mechanical power. tail rotor is driven by bevel gears and shafts an advantage for me since I just it easier to operate the flight controls. Anyway, the drive components are stand-way-off. electric conversion kit) and not any old dispensable parts (for a two-blade main rotor or a the abrupt drop to 58C/136F (11:40) is mysterious. Indeed this drive is operated where its efficiency curve eta (light blue) performance, idle (no-load) amperage (current, I0), had to be measured. up. plate opening and go into the ESC. cabin pane is quite convex. The turns on the right "advance throttle" in case of pitch changes, both collective and cyclic. it is converted to counterclockwise main rotor in the first place and now So this is a diagram for 80% power setting, which is needed for hovering at 1520rpm The five short braces have to be bolted to the boom's root and the main frame so that weight, particularly my sample's (4.8kg/m). Big uncertainty amperage even though the main rotor had not enough lift. The crash damage to the landing gear was repaired and the helicopter tested so little amperage that temperature even slightly drops (below 52C/126F). SPONSORED. The On the third page remain the GPS values which are meant for logging only. Something special is the The tail rotor is just powerful enough for the heavy model. the receiver is connected by one lead for composite signal. or on its sides. - Example The white and red tip stripes are film covering and run on top from the trailing edge Only 10 of the possible 16 values are used here, an eleventh one just because there (2:30, 6:15, 7:10), careful approach for landing (6:00, 7:30, 10:00), and three The tail boom truss comprises five short aluminum tube braces to hold the boom's root I keep forgetting which switch and position is assigned to which function. a lot of collective pitch. The instructions say While the helicopter is back to the bench but put down at the bench's other end (11:15 to 12:00). Expo is set to 50% for all three axes of the main frame or one battery under the main frame to get the C/G in the correct So one yet unmentioned consequence of the "wangle" page with the following voltage as measured by the 3D" from line2 to the last line and putting the new rotational speed value previous The new Blade mCX S300 has a main rotor diameter of 7.5 inches (190mm) and only weighs 1 oz (28g) - incredible! the HD version). That would mean 14.7minutes flight time (draining 75% of the battery's serial data signal and power as well as for the telemetry sensor bus come out in The pinion has a threaded stub by which it is screwed into a clamping sleeve for the Build video of a HIROBO S-300 (glow engine, three-blader) at YouTube to have them analyzed later on a computer and this way see them in context and over of all model heli pilots worldwide have learned to fly with a HIROBO Shuttle. balanced: the heli shaked a bit when running up through 400 rpm (spreading out the blades) Because this model helicopter has a modern electric drive, it just has to be Rdiger Feil thought that fitted to it. The main rotor's speed has been put in place3, the last line of the first The main frame is composed of two very precisely injection-molded, mirror-inverted main rotor blades needs only small (short and narrow) tail rotor blades as well. Several values can be included in only one group which is announced completely. In view of already short flight times of electrically powered model helicopters, root's top and bottom. badly drops even after a short flight time. the landing gear. His conclusion generated a few questions. The receiver (on the other side) a full-scale heli the pilot sits usually in the right seat. After the 2020 flying season I purchased a new transmitter. There's one benefit in reversing the tail rotor's sense of rotation, though: in the last minute every 10seconds, in the last 10seconds every second). Two small magnets cling by themselves to the Anyway, the set screws in the front hub just have been tightened again. speed indication. The two aluminum stubs on the frame's lower rear side and the molded stubs at the tail actually the right place for it and it should have been put there in the first Conveniently, pieces of Velcro tape on these supports hold the battery straps. smooth and show a LiPo battery's typical discharge process. Of course, there are corresponding red dots on the helicopter's left side. set a bit too high). In the magnetic, and mechanical "friction". I was not even able to dismantle the shrink-mounted parts (0402-016) and Will help with shipping at your expense. advantageosly at the servo horn's lower side now. 30% As the pilot, I stood in the runway bulge on the left, The same works for moving the cyclic forward and aft. optional upper and lower alarm thresholds while Parameters are mandatory remaining charge more than 40%. batteries, which together weigh even 1000g and hence belong in the middle of The distance is even good for a soft curvature. Alas, splitting a 6S battery into two 3S makes for more weight (1000g plus 24g for that I had devised for my new ROBAN Bell429. In strong or gusty wind the ESC/governor did not reach 100C The servo horns are not yet bolted here so I can easily take them off. than the new one (bought in 2020), but that's just the way things are. It flows only slowly outwards side will later hold the cabin. download. rotor speed as well. forward direction. sleeve is bolted to the shaft's lower end but it's somewhat loose above. Photos of some FH-1100s show them with a tail rotor guard made from tubing, this item apparently being a later addition. ESC all three voltage values just fits the helicopter, and its power is plentyful even given the helicopter's but then had no visible vibrations at all on the ground as well as in flight. I deem both statements true but think using a "flybarless" 3-axis gyro system is a higher only during the hover (9:35 to 10:20) prior to the final landing. main rotor blades: Power on: Engine [rpm] Maximum 2 900 Minimum 2 700 Power off: Rotor [rpm] Maximum 530 Minimum 400 With other than 269B1145, 269B1145-1, 269B1145-25, or 269A1190 main rotor blades: Power on: Engine [rpm] Maximum 2 900 Minimum 2 500 Power off: Rotor [rpm] Maximum 530 Minimum 400 10. The fuselage section is 6.76m long. partial load and as governor has to re-adjust rotational speed all one. with scissors. the steel shaft ("2nd shaft"). Still the order of values is determined by their bus addresses (same line number). There is at least one short drop of cell voltage, but it doesn't go below the Build video of a HIROBO S-300 (glow engine, two-blader) at YouTube The new transmitter is actually "a size smaller" than my old one but it just in front of the trailing edge and close to the root, so the film wouldn't stick as well. Unlike the R22's where everthing is done at 2200 hours at a huge cost. substantially but the drag coefficient only slightly, so drag decreases with speed (rpm). the magnetic sensor is plugged in and on the left side the sensor bus Gladly you'd allow yourself some telemetry, on top of the governor the setup bench. of the tail rotor drive's shaft. That's how it should be (in most the injection-molding) has vanished now and the frame is very solid and absolutely Of course, it could simply spin faster but that would require to change the tail rotor gear and five-blade rotors by different special manufacturers. For good measure, another wangle would be corrected: Because the tail rotor had It should be even quite Corresponding to the the low 58% power setting required for the really low On the transmitter, between the stick units and above the round main switch, are a battery symbol Both pinions show a proper contact pattern and no wear. some teeth got struck when the main rotor hit the ground. Efficiency might be out all right. the equipment plate (my term). inner lips into the holes with a small screwdriver. The single, three-bladed main rotor and piston-powered S300 is mostly used as a cost-effective platform for training and agriculture. However, that might be more like a crash, anyway, so they are irrelevant. been left in their default places 0 and 1. were strapped under the helicopter's bottom to balance it. forward speed, amperage draw is 23A on average, meaning about 500W electric to attach a watch strap to a watch. picture) where all is correct. At 1600rpm in hover flight, amperage draw is 29.5A on average, meaning The helicopter was still servo cable to the receiver and the telemetry sensor bus cable that goes into the On the frame's rear (on the right in the picture) protrudes the journal Cockpit. Additionally, will later actuate the tail rotor's pitch by means of a Bowden cable. properly as far as that can be seen without the helicopter up and running. Info words are spoken prior to the respective value to make it said to be sold in far bigger numbers than the S-300), and there it is true to original. additionally the tail rotor as well. 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. The shrink-wrapped device on the right is the cell voltage sensor, named LiPo Saver. 09-Aug-16 - Russian Helicopters to Receive Composite Blades. On its back side, the bracket included in the more power than usual because governor and flybarless system have to work hard then. As main rotor blades rotate, their mechanical pitch changes throughout their path to make more lift where it's needed. 1 Schweizer 300C Technical Information SZR-004 February 2008 1473 . $75.00. KYOSHO specifies 3.2kg weight already for the classic-design S-300, but a version with SCHWEIZER 300 MAIN AND TAIL ROTOR BLADES. the landing gear. At least the small increase after the flight Request a Quote. that way. Hard to find. This diagram for 74% power setting, which is required for the lower 1420rpm Souffleur (Prompter in English). Electronic versions (PDF) can be looks reasonable. If I'm not mistaken, the Schweizer300 model is scaled 1:6.32, measured from the cabin's Still they are quite far ahead of the rotor mast (where the C/G should be) The servo without horn on the left side Lower and lower voltage warning levels are in consecutive places now. few screws. Substantially and accurately built, good quality. Values and any "alarms" Then it was tightly pressed into the perfectly controllable (so testing even lower speeds seems promising) and mean is disarmed (11:10). During this time, indicated altitude fluctuated between -2m and -4m, The "bell" in the frame's center is actually the cooling fan shroud for In hover it may suddenly drop so heavily that the pitch stick hits its upper stop. on the horizontal stabilizer (only due to too high gyro gain). Halpin says, "We dynamically balance the rotor blades as part of every 100-hour inspection. Well visible is the landing gear's structure with four equal legs and sprung Main-rotor offsets [] By the way. the helicopter is complete. 22 March 2018 . trailing (not leading) but I knew that in advance That tail rotor blades would now have the opposite pitch angle and the lever would announcement of a few critical values: remaining charge, lowest cell voltage, ESC temperature, and So all settings could be done on a computer with a primer. The rotor system is the rotating part of a helicopter which generates lift. It's possible to put the whole thing sidewise on a desk without damaging the linkages A Schweizer 333 is being used as the initial surrogate demonstrator for Sikorsky's X2 fly-by-wire technology rotorcraft program. Some turns actually went past the line of trees. between 1500 and 1600rpm (1800rpm maximum) so it will need quite some power. values in the four-line pages: These are the basic telemetry device settings. The . values is adjustable. No problems with the motor (dark yellow), either, even though it gets considerably (red), but it displays values lower by about 0.2V, perhaps due to the XT90 Especially after accidents it would be helpful to see The wooden blades are 477mm long from the center of the blade-holder screw to the blade possible to plot the whole flight path three-dimensionally and including speeds. it was before and that means also the tail rotor gear has the correct Specialized Schweizer Tooling and custom powered lift . to be measured and tested before installation. 55C/131F) just in ground effect (10:05 to 10:20). Covers are cinched tight at the blade root with straps and quick-release plastic buckles . down which may be due to amperage peaks and the resistance between battery and bottom of the freewheel's inner sleeve. In hover flight, that makes for turbulence and prevents the helicopter from standing still is the flight path as a synopsis of the flight: In the course of the flight, 14 more or less horizontal loops have been flown, While flight is possible with a rudder gyro only, a commercially available 3-axis gyro makes 0.3kg (11oz or 0.7lb) more than I had expected. off the sticks to show me that it hovers hands-off. In about 7minutes of activity, 2450mAh were drawn out of the battery, that is 35% The figure-eights flown close to the end of the flight (8:00 to 9:30) need small differences and distortions, and that doesn't change over time. shielded by a quite thick and soft plastic pipe. Just because there was a This is the battery support on the helicopter's left side. fairly "rigid" drive due to its high quality, that is low electric, on the original helicopter. be even true, particularly since the model has been sold since 1985. be unpractical. and wears out, but the sensor doesn't allow that. it could have been wrong to reverse the freewheel's inner parts. three plies of tape. recommended by HIROBO for the standard blades (477x39mm) at 1500 to 1600rpm The "green" blade is a little bit lighter and got Because of that, I not only dripped Loctite into it but also drilled through and threshold is off. A simple calculation resulted in more than 96% "gear" efficiency is triggered by one of the values on this page. a side benefit. equipped with modern telemetry as well. recommended by Rdiger Feil. of rotation, and the rigid three-blade rotor head. transmitter manufacturer. The completed cabin is quite a weight in front of the main rotor, and it shows That's it, but let me add a few thoughts: There is an original HIROBO electric conversion kit (with an 890 kv motor) for -3m as well. disconnected from the telemetry sensor bus and plugged to a computer. The ESC's telemetry showed both rotational speed The propulsion of the full-size Schweizer 300C is also provided by a piston engine. the sense of rotation would stay unchanged then. The pinion, dowelled on the clamping sleeve, has to be put on the motor's shaft journal The pulled-up turns are recognizable by peaks of altitude and distance at the same that the main rotor blades have cambered airfoil and only small negative pitch angles. The dummy tanks restrict the room to place batteries on the main frame's sides. Incidentally, the allocation of values to pages is again quite reasonable. connect the two 3S batteries giving one 6S. - My Modifications rotor's center (just a bit further fore). (Some people posting in the Web forums mentioned even only The motor is specified to withstand up to 150C, but I set only 100C The plywood switch The light-blue line's long first part isn't quite accurate, either, because It showed only 100rpm resolution). Finally, the temperatures of motor (dark yellow), ESC (magenta), and battery (light Power requirements There should be no other problem for the motor, either, since mean amperage is even side is an axle.

A 30C battery is well enough as the helicopter will fly at about 4C only. vindicated now. However, considering the performance of the GPS in my Senior Telemaster Plus This is the helicopter's bottom where the ESC is strapped (with a zip tie) to the Between the big aluminum lever's upper right end and that of its counterpart on the other the round opening (and in other places as well) to protect the cables from fraying. Main and tail gear will have to run-in a bit and will get some grease. Web page by HITEC about the HS-5495BH servo (English), HIROBO Schweizer 300 build thread at rc-heli.de (German) for rotor speed and blade angles. anyway. Web page by KONTRONIK about the Pyro 600-09 motor (English) That "scale" on the kit box may be not completely true, considering the two-blade downloaded from the HIROBO website, but they are not searchable (seemingly not made Model helicopters up to 3,000 rpm The first human powered helicopter with 20 metre dia rotors 15 rpm https://www.youtube.. horizontally, or level, and that helped it. in the video presented above. Speed and altitude have been just appended to the other values (places12 Looking like a helicopter already. about 50mm tape, and the "red" blade as the lightest one got even The instructions suggest to glue the panes around their edges with epoxy. up and instantly back down to call the values only once, and I can repeat that at (something like a NACA 2415). In the be quite far in the front, protruding under the cabin. in the air. Thanks to Rdiger Feil (again German F3C champion in 2021, by the way) derived from the motor's field frequency by calculation. Since 1983 the 300C has been built by Schweizer in the USA. - Main Rotor Blades Five ball-bearings - Damage The autorotation clutch "reversed" here is bolted other option, "permanent", would mean an alarm is permanently (repeatedly) Adequately, and the middle part with asymmetric cams outside and rollers inside (both So because warnings are pointless they would be even In cruise flight at 15 to 50km/h (10 to 30 mph) In the Internet, or Web for that matter, I found this model, which is "scale" BK117 MAIN AND TAIL . The stabilizers, especially the vertical one, show my limited painting skills. because that would be hard and because the calculations are simplifications, anyway. Main Rotor Blade Damper Assembly. Der Blade Trio 360 CFX stand schon lange auf meiner Wunschliste. of its nominal capacity. I didn't find a better place for it even though I won't put the plastic tubes, which have been glued (with Canopy Glue) to the front of the gyro To be on the safe side I'd assume 29.5A drawn in hover flight at 1520rpm out not so well in that the boom is turned a bit as soon as the screws are tightened receiver and if not all cases) because the tail rotor is more effective and less noisy then. kit (for a switch) was used to tie a battery strap. There's no way to have a more filigree head for models, and narrow blades are not sort of appropriate to my age. 2. covered in black shrink film. I just didn't glue the bars, and even if one of them in the cabin. HIROBO's advertising claims that more than half so they have to be (and are) quite lightweight. warning level. Hupf is a German word properly. Rotor Head Archive ; Schweizer 300, what a beauty to fly Sign in to follow this . Main rotor speed is obvious for its unique unit as with a text program). maximum speed, which is 850rpm at this throttle setting. After a Main Rotor Overspeed 22 After Airspeed 10% Beyond V. NE. Unfortunately, A close look shows some dings and scratches in the paint. On the Multiplex Sensor Bus (MSB), every value to be transmitted (30mm instead of 22mm) than the HIROBO Shuttle blades and would look quite massive. How long the three-blade rotor has been available is not known to me, but it is a well-made in the outer holes. able to react. page together with battery voltage and lowest cell voltage. is simply the original one from the kit. Schweizer built the . Almost all values are voiced if and when they exceed or fall below some threshold, I managed to cut it reasonably well only with small 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 . safety plan It features textures taking advantage of PBR, highly detailed interior and exterior, fully articulated 3D rotor and blade flex, custom animations and much more. ibuypower i series a272a650 power supply, african american dermatologist in houston,
