I've got a trex 3dpro (yellow one)I'm also new to the rc heli hobby.I'm not new to the rc hobby but still new to the heli's.I have to say even though I'm having trouble getting things right on my chopper I love it!It's a challenge to say the least(I built mine).Any way like I said I'm having lots of trouble ,it seems like my trex is spinning up the wrong way....? I read somewhere that the rotation on the main blades should be clockwise and the rotation on the tail blades should be counter clockwise,is this right?My tail rotor is clockwise running just like my main blades.I replaced the main drive gear after striping it out on a spin up and I might have put the one way bearing in backwards if I did would this cause this.I do have a lot of questions on my chopper but I'm learning and I want to try and get as much done on my own(I learn better that way).I have the eclipse 7 tx also.So any advice or help would be nice.
