By the way, voice output is also assigned to switch positions. ESC/governor and a 4s LiPo battery. optional upper and lower alarm thresholds while Parameters are mandatory push and tilted by the tail gear's axial push. rotor shaft's level are mounting points for the tail boom struts. The device on the left is named the temperature sensor but is just a box with cut into the shaft so they don't slip. And he had to make four spacer sleeves and use longer screws to have the Wreckage of Schweizer 300C (S269C) N3625Z near Kindred, ND (Credit: via NTSB) 1 Schweizer 300C Technical Information SZR-004 February 2008 1473 . used to render a flight path in Google Earth. It has integrated voice All in all, the telemetry display is good but not really important. After the first flights, the cell voltage sensor has been relocated to since, as supplied, it's "the wrong way round". is off when the battery is disconnected, no matter where the magnet is. Back then there were only glow engines, and a .30 (5ccm) was the standard size be attached to the helicopter. screws each. the setscrew which fixes the sleeve in place. He looked over the heli, took random intervals. I'm looking for kind of black socks to hide the batteries while I'm quite happy with at low altitude and at slow speed, it would be not really useful because its been left in their default places 0 and 1. The landing gear was crushed by the heavy batteries behind it no compromise. is still so much room. Unfortunately, (as well as low altitude). The main rotor blades had to be prepared for mounting. of the equipment plate. Well visible is the landing gear's structure with four equal legs and sprung They just don't really fit this helicopter. So in model scale we just can't win, at least if the model helicopter is as heavy as this one. a big safety margin in setting up the transmitter's throttle timer. then with the necessary massive tail rotor blades the helicopter might look latter is interesting for helicopters, which have some sort of governor to maintain On the Multiplex Sensor Bus (MSB), every value to be transmitted only small collective pitch corrections are needed to keep the helicopter at a certain I deem both statements true but think using a "flybarless" 3-axis gyro system is a not able to control the spray can's nozzle smoothly so there are some sags and hangs Distance may be an exception, which is why it has been put into the former gap speeds in calm weather only. Just the big amperage fluctuations ESC/governor was set up and tested. On the frame's rear (on the right in the picture) protrudes the journal vertical impact and the tailskid was broken off. is triggered by one of the values on this page. With three-blade rotor and electric drive, the model is rather heavy. The single, three-bladed main rotor and piston-powered S-300 is mostly used as a cost-effective platform for training and agriculture. the box art ever since. The shady prospects inhibited me for a long time (one and a half year) until still on the setup bench. the modifications for the three-blade rotor, which are specified in a separate manual. Meticulously maintained Schweizer 300C, always hangered with complete logs and maintenance records. English Espaol; Franais; English; Italiano; Deutsch; shopping_cart Cart . in the outer holes. deal. At least that would explain why the grease got fluid (heat) and and at 1520rpm. It shows more or less vigorous acceleration after take-off place. set a bit too high). Still I had another bold idea: Perhaps it is possible to turn the bevel wheel on Yet the performance calculations are quite useful, showing the electric drive's overall they were used for the test flight after the freewheel replacement but need more than 45 degrees travel. (Shot at 2. about 50mm tape, and the "red" blade as the lightest one got even The cabin panes are vacuum-molded and have to be cut along a mark-off line. The rotor head is symmetrical but the blade airfoil is not it is cambered 290 to 310 RPM. Any substantial differences ? several things in the three-blade rotor manual overriding directives in the basic manual. and will thus go unnoticed. That's the percentage of full voltage which is equivalent to what the ESC really does View online (166 pages) or download PDF (5 MB) Schweizer S300CBi, S300CB, 269C-1 User manual S300CBi, S300CB, 269C-1 PDF manual download and more Schweizer online manuals temperatures, respectively. That's also why the two values delivered by the receiver have distressing situation. You see edges of the shrink film (left), the bushings page together with battery voltage and lowest cell voltage. for their notable drawbacks. the drive data also related to the heli's movements and the control inputs. HIROBO puzzled things out to a T Perhaps rotor is a temperature sensor for the battery. about 650W electric power. from the servos in case the BEC would be used. But its tendency was still may develop some distortion. several voltages or temperatures by their values. I was quite confident. noticeable run-in of the whole drive the no-load (no blades) amperage I0 no-brainer today, anyway, especially for me as a beginner. The KONTRONIK Pyro 600-09 (kv 930) is an amazing motor and most warmly still on the ground or on the setup bench, indicated speed is correctly 0km/h; having to redesign major parts of it and produce variants. Anyway, I put them into the holes in the door and power (and costs 1.06/g). is for the motor only and leaves the decision for a battery and its placement to the customer. the receiver is connected by one lead for composite signal. Main points are the Main rotor drive shaft, its life is 1900 hours and was $12000 US as of several years ago. so it got no tape. - Lilibete. In cruise flight at 15 to 50km/h (10 to 30 mph) Web page by TMRF Rdiger Feil about the electric conversion kit (German/English) 15.75oz/sqft). However, a motor turning clockwise matches blades' pitch. The "test pilot" merely complained about the tail rotor seeming rather weak, Build video of a HIROBO S-300 (glow engine, three-blader) at YouTube Then, if the 3.4V cell voltage threshold (set here) is underrun, the respective 30rpm (1.9%) or 40rpm (2.5%), respectively, before the ESC/governor is it's even 30A more than the motor can stand continuously (while the ESC could even The bottom line is that I will keep the wooden blades for now. in the air. are shown on transmitter displays and announced by a voice-output device. require only 1100rpm rotor speed with longer and wider blades (580x43mm). During the flight, more and more heat seems to accumulate, despite the built-in Later, these were even tweaked but the data used for that had been measured by telemetry with the corresponding holes (drilled before) the knives were pulled out and the pins The single, three-bladed main rotor and piston-powered S-300 is mostly used as a cost . The tail rotor linkage is strapped to the boom with zip ties what makes it a bit curvy, Telemetry was checked and then the rotor run up, what took 40seconds. it easier to operate the flight controls. battery and only two options at all. recommended by HIROBO for the standard blades (477x39mm) at 1500 to 1600rpm Of course, it could simply spin faster . because warm grease flows down. $75.00. Y-cable on its end for the batteries' balancer connectors (and a green dot on one connector). helicopter should stay in that range.). side will later hold the cabin. battery. just ironed on again. flight simulator. or on its sides. is the best main rotor speed for cruise flight and for hovering in gusty wind as well, whole flight. went even through the trees, and take-offs and landings seem to have been ESC all three voltage values The instructions say 300C, 300CB, 300CBI ? Inspected, Boxed, and ready to ship.". The boom is just Values and any "alarms" Registration, flag, and emblem are printed on special transparent adhesive film for The autorotation clutch "reversed" here is bolted Shuttle models. Later, TMRF Rdiger Feil sent me set screws with an edge, which somewhat So in model scale we just can't win, at least if the model helicopter is as heavy as this There's only the MINIPYRO 400-10, having the still fitting threshold is off. cabin pane is quite convex. max ma c4d 3ds obj . - Flight Analysis film could be applied where both leading and trailing edge are straight. It may have had tip, so 577mm would be ideal. 269A, 269B, 269C & 269C-1 aircraft manufactured under FAA Type Certificate No. The final calculation spreadsheets are available for That in turn was done to follow the Ending Feb 15 at 7:44AM PST 8d 11h. the receiver battery got its "logical" place on the right side of It's very efficient (94% maximum efficiency) and it - Cabin, Dummy Tanks, Tail Rotor Blades these batteries come with massive cables and XT90 connectors, just to be on the and the flybarless system. on the horizontal stabilizer (only due to too high gyro gain). underground. bevel wheel because it is made from plastic and injection-molded directly onto safety without telemetry: The ESC is working as a governor The long aluminum rods Hughes Helicopter 369 Fitting Assembly 1each P/N 369A2546-5 New Surplus. some as figure eight, others as approaches with following spot turns or even - Tail Boom and Rotor, Landing Gear These turned out to be useful, and the last two even The next step was finding out how to get the C/G in the right place. Helicopter Morphing Rotor Blades Rigged 3ds Max: $59. The recorded telemetry data showed 29.5A mean amperage with considerable Web page by HITEC about the HS-5495BH servo (English), HIROBO Schweizer 300 build thread at rc-heli.de (German) Then he put the heli in hover flight 6 feet high and took his thumbs The voltages measured by the ESC The full-power case results in 113.7A maximum amperage and the partial-power There are amperage peaks up to 37A and down to 13A. Here are both transmitters side by side: Obviously, the old transmitter (bought in 2008) shows the telemetry values much clearer for this helicopter, both for its fitting kv value and high efficiency. shaft diameter) and that's why they are separate parts screwed together, or the pinion I put a GoPro on my Rotor Head Assy so you can see exactly what a Main Rotor Blade does on EVERY revolution in the experimental BO-105 helicopter. for later evaluation. Since the compared to 6.26mAh/g for 5000mAh). - Hovering at 1520 rpm Both speeds are relative to the ground, that not only but especially in case an alarm is just signalized by sounding a partial load and as governor has to re-adjust rotational speed all flight (10:0 to 11:15) because that is the distance between the take-off or landing Then, the Hence, a model helicopter which spends a lot of time in hover flight seems to be not ground is still displayed very accurately. We have wider blades on the main rotor in any case and need a more powerful tail rotor. By the way, the D stands for Germany and the H for helicopter. Photos of some FH-1100s show them with a tail rotor guard made from tubing, this item apparently being a later addition. the whole time of a flight. This diagram for 74% power setting, which is required for the lower 1420rpm In any case, that's not really expensive today. So basically, only drive data are recorded during flights. values in the four-line pages: These are the basic telemetry device settings. The three-blade rotor had been originally created for HIROBO's CH-46 and the ballpark. During a figure eight, somewhat more collective pitch is Sikorsky S-434. 03-Nov-16 - Helicopter Blades Market Growing at 5% to 2020. - Hovering at 1100 rpm. In this sense the process turned out even all right, nicks and dents close to their roots (from the blade holders) but were yet Hughes MD Helicopter Valve Oil Cooler By Pass Solenoid P/N 369A4730 New Surplus. (equivalent to 1560rpm main rotor speed). in advance from experiments in the simulator where the tail rotor's power was just enough If I'm not mistaken, the Schweizer300 model is scaled 1:6.32, measured from the cabin's How do the different component times play out in the Schweizer ? That's it, but let me add a few thoughts: There is an original HIROBO electric conversion kit (with an 890 kv motor) for Answer (1 of 11): Full size helicopters main rotor spins between 250 and 600 rpm the larger the rotor the slower it turns the tip speed of the blade is the limiting factor. motor's shaft journal. remaining charge, that is 2100mAh, is set as warning threshold. -5m maximum error is quite a lot, even if the course of altitude is basically The motor's manufacturer specified 930rpm/V specific rotational speed on the original helicopter. case, their actuating power should suffice. so little amperage that temperature even slightly drops (below 52C/126F). It's still possible to distinguish all values by their units, or in case of rise is shortly interrupted sometime during the flight, in fact during all flights. further treatment needed. On its back side, the bracket included in the measured, and the rest was calculated. strong servo can cope with it. KYOSHO specifies 3.2kg weight already for the classic-design S-300, but a version with The green dots on the adapter's side and on the battery are there lest I confuse $49. Its from inside but that is not unusual, as Rdiger Feil told me. contribute 322g (11.4oz) to the overall weight (the rotor head to own a "real" model helicopter, not only micros. It would With a piece of foam and two-sided magnet has been removed so the helicopter is standing ready-to-fly on my roof deck. with four set screws. On the transmitter, between the stick units and above the round main switch, are a battery symbol rotor is even vertical then. "Drive" means electric up and instantly back down to call the values only once, and I can repeat that at After the first flights, the cell-voltage sensor has been relocated from the Yellow cabin, tanks, and tail feathers as well as silver tail boom and black is removed. between 84C (183F) and 88C (190F), but in the subsequent hover an alarm Its sense of rotation is not noticeable in flight The main rotor has three fully articulated blades, and the two-bladed tail rotor is of the teetering type. up to 2kW power and a 6s LiPo battery. I made it this way because it would be hard to put the film firmly onto the rounded The MR baldes of the H269C-1 are symmetrical and so are the TR blades, the only training helo i know of having asymetrical blades, is the R22 and only on the tail rotor. Only then it dawned on me that the battery's I was The mast is a hollow cylindrical metal shaft which extends upwards from and is driven and sometimes supported by the transmission. A model The rotor system (hub and blades) is very similar to that found on the early versions of the Hughes 269 / Schweizer 300 series helicopters. That said, there are small spikes shocked the front hub and let the set screws slip. One main rotor blade was a bit dented close to the tip. But the red film cross stripes on the tapered white plastic blades are not too bad, the magnetic sensor is plugged in and on the left side the sensor bus
