Hi, i just receive my second heli,but i have a problem with it. My rotofly just want to go to the left. when i give some juice to lift off the heli go straight to the left. i put some trim correction but no effect. i pull thes tick to the left no effect. The swashplate seem to be o.k. What can it be ??? i re-done all the ajustement no effect. what can i do ?

no experience with that heli, just make sure everything is symetrical and balanced. Then with the motors unpluged(if possible) see if the swashplate moves with the trim lever. just something to try...
