Thats the puzzeling part, it seems to run good in the air as well on the ground untill the landings and it will die about 1/2-2/3's of the time.
It has all new linkage and a good servo operating things ,so I don't think its a slop problem,but again I was going off what I was told and didn't see it first hand.
I did notice when going from full throttle on the ground to idle the engine would go to a slower RPM than normal and gradually pick back up, thus thinking it may have been to lean on the bottom.
Thanks for the info I told him about the tube and line going to a bottle which I use on all my gas engines but the owner had that deer in the headlights look on his face.
