TO daven. I just co mp leted the arf and it really is nice.I did not have any binding on the elevator or aileron linkage like you are having.Also built the kit and did not have any problems.You might try some silicon spray.It is pretty slippery.I have two Magnum 30 4 strks in mine and i am planning on leaving it togethrt for transport as it would be a pain to assemble at the field. Tim.
