Hey guys while I reput together my trex 450 clone and set the linkage`s to book specs I couldn't get it to leave the ground. So I went away from spec and just leveled my swash and washout arms and it flew good. As a matter of fact it flew good enough I thought my skills were better than they were. So after the crash I replaced the bent main shaft and checked the feathering shaft and it was ok. My problem is that after adjusting blade tracking they seem ok at low rpm but separate quite a bit at high throttle. Any thoughts on that?
