RE: rx crystal change
Tigerdude,
This thread really doesn't apply to your situation because the original post deals with Futaba receivers. On older Futaba receivers they are tuned for use in two bands that split the channels in half, a low band and a high band. If a low band crystal is put in a high band receiver, or vice versa, the receiver will not operate as it should and could cause a loss of the plane.
In your situation you will be fine. Hitec receivers aren't banded like Futabas are.
