RE: How do the cheap 2.4 radios work?
Yeah, that's apples and oranges. Those cheap radios are just that. You can fly the quality systems together with no problems. There are some pretty good deals on 2.4 Technology now.. Airtronics RDS8000 with two receivers for around $200 or a little more, and the latest release of the Spektrum DX6i are nice radios. I've not flown with the Futaba 2.4's but I would imagine that they are up to the standard outstandingFutaba quality.
