Got power from main lipo through some filters.Ĭurrent in hover - 13Amp (by ET data logger) I found that my current props are doing best for my config.įPV camera KX191 with video tx 500mW 900MHz. Of cause at the expense of current consumption. I've tested mine and got about 400-500g load capacity. If you put bigger props, say 11x4.7 or 10x4.7 you can get away with more load. This way I can hover at middle stick and can control rpm more precisely. Starts with 20 (in my case motors is about to start at this point) and get some flat curve at middle. Tail Gyro in HH mode - 85% (little bit of a drift, may be because of vibration but this is ok) When I put FPV stuff on it I even lowered gain to 16% - still stable but less pron to vibrations. Tail gyro goes as usual, to rudder and gyro channels and controls servo which pivots tail motor assy.Īrms Gyro gain in Normal Mode - 10% flat on throttle channel (this is Futaba radio) I've tried 8% and got just tiny bit of shaking. I don't use external BEC, just all 3 ESC's voltage regulators connected in parallel through common power bus. So total expenses to build tri is 91 bucks and one weekend to tune it.Īrm gyro's input connected on A, E and P channels on rx, all 3 gyro gains are combined and connected to Throttle channel. ![]() ![]() Some lipos 3s 2200 (got plenty from Trex450) Radio - Futaba T6EXHP 72Mhz ( just had a free rx for it, so using it instead of my DX7) Gyros - HK401B (3 in rate mode, DS on and tail in HH mode and normal) (4 x 13 bucks = 52) Props - GWS-RD-9047 (needs to be balanced before use) Overall I think I can get used to these differences in piloting tri-copter. I found that better to trim tri-copter using correct CG, this way it can hover 5-7 sec. Tricopter handles it well, just small bumps. The video above is done with some wind gusts up to 10mph. So, again, smooth and small changes is a key. I think it's due differences in ESC, gyro channels, once you have it tuned at hover level it wont stay in perfect tune at different power levels. On rapid descend, tri-copter become unstable and have tendency to flip over. Changing altitude - a bit lagging too and sensitive, tri-copter can tolerate rapid ascend but does not like fast descend at all. Turning has a bit lagging response, it's understandable, cause of that motor pivoting thingy. It's somewhere easier then CP heli but somewhat different. Well, I'm flying CP helis for 3 years (some 3D moves etc.) and on a scale from 1.10 I can give tri-copter solid 4. with lack of peripheral vision and intimidation of 600mm CF blades swinging at 2200rpm.īut I always crave for "heli" style FPV and here we go, I guess, tricopter is a ticket. ![]() I never dared to put FPV gears on my helis, even on T600. Crash9, I saw you are flying Tre圆00 and even T450 by FPV.
