RE: Crystals?
There are alot of varibles that need to be explored befor awnsering the question. Are the radio transmitter and the reciever compatable, ie are both Futaba or Futaba and a Hitech that is designed for Futaba. Are they both FM, AM, or PCM? Just a few thoughts. If they do match up I would do a rather complete range check and vibration test befor flying. Hope this helps, Dave
