If you were going to purchase an all around radio for airplanes how many channels would you suggest?? I am thinking 6 or 7 with the 2.4hz technology. Then what manfacture provides the most bang for the buck?? When I flew years ago I had a Futatba radio, but that was a lot of years ago. I am going to get back into it with a HZ Super Cub. I know that the electronics supplied with the plane are marginal. That is why I am curious as to what you guys think.
