In other words if you try to fly your plane with the car reciever you are begging the kid around the corner playing with his car to crash your plane for you. Tell us more about your Hitech reciever and JR transmitter. Someone here might be able to hook you up with a swap either a Futaba transmitter for your JR or a JR receiver for your Hitech. This is not a Swap forum but in the spirit of "Pay it forward" maybe the moderators will allow some discussion on the matter.
