does anybody know of a company that does bluetooth Tx's and recievers as i guess this would solve the problem of interference. the range might notbe great either. ah well.

It would be fine if your flying in your living room, but a 30 ft. range isn't that great for RC.

Well, I've got a Treo650 and a bluetooth earpiece and I still get quit a bit of interference. I would be about the last person on the planet to try a bluetooth rx/tx.
plus yeah range AT BEST is 30 feet.

hell, even my mouse/keyboard are bluetooth and my mouse gimps up at least twice a day....

The next generation of RC control is spread spectrum ... already being for ground and park flyer systems.

i guess wi-fi would give greater range?
