I have a FMS P-39, Have not flown it. After I built it I found that the prop without power to the motor felt like it had tight bearings I called MRC I spoke with one of the guys who said run a battery through it on the ground and it should loosen up.
Did that. What is happening now if i run it for awhile and then with power off turn the prop it is very stiff ( tight bearings) put after it could down spins by hand o.k.
I removed the motor from the plane, turning the can by hand if feels fine I feel nothing in the bearings and the can turns as it should be run it gain and it gets tight....
ANY body have any idea's???
