My Posts This: Topic Forum | Hey Guys,
I'm back working on my 1st VE, the one that started this thread because I couldn't get it to fly. Well, I'm back in the shop and I still can't get it off the ground. Here is the problem again. As the rotor head spools up, it's spinning at around 1800 rpm. This is with an astro 20 with an 8 cell 3300 mah pack. Now I know that supposedly this isn't a great motor, but still it should fly and be good for mild 3D, right?
Anyways as it spools up and it's about to lift off, the rotor head dramatically reduces it's speed to around 1000rpm's and the heli starts to get a very bad wobble from the instability. I've checked the 2 main gears and they don't rub, I've checked the main shaft colar, it was set tightly as I pressed down on the rotor head and there is no movement, I've checked the tail belt drive and it is not tight, and I'm running a 15 t pinion so there should be pleanty of power. None the less, as soon as I get to half stick to get into a hover, the motor starts to strain and it will not lift off. I also have checked the pitch. I'm -10 +10 and at around +4, +5 at hover/ midstick.
What now??
thanks for any tips on this crazy ship,
