RE: adding pump to jett 90
You see, it's always something stupid isn't it?. We had a guy here a few weeks back. Takes up his GSP Corsair which he has flow countless times. For some reason the elevator is out of trim and cant keep consistent. Says the heck with it and lands.
Checks out fine on the ground. Blows it off and takes it apart to go home. We turned the tx on to check out the inside and the whole servo tray was loose thus causing all that movement.
That GP F14 is a nice plane.
