| Well, you see, I'm currently running 400mm blades...... During some testings I did stripped the main gear...... On that one the fix I came about was adjusting the backlash a little tighter..... A hairline tight, how I could describe it...... My HS now is at 2800rpm range with 18T pinion and pitch range of +/-11*..... And, so far, I haven't stripped the main gear yet, I'm crossing my fingers.... My motor have quite a lot of torque.... A couple of guys in this forum agreed when thay tested it...... I was doing some reconfiguration earlier...... HS was hitting 3200rpm with 20T pinion..... Quite scarry...... The whole heli was vibrating in a hover..... Not violently...... But as it does I could actually feel it in my skin through the air..... So I went down to 18T pinion.... I'm sure if I was using 425mm blades I could have stripped the main gear again during pitch pumping...... |
I guess that is why you pay for what you get
