There have been several guys in my club with the DX-7 and they have seen the radio spend more time in the shop than anyplace. They've had nothing but trouble with it. If it was one bad radio I wouldn't worry about it, but this is several very experienced fliers who have 2 or 3 of these radio's and they are not very reliable for them right now. Two guys lost planes to DX-7 radio issues this week (one radio was just returned at the beginning of the week from Horizon), one pylon racing and the other practicing - both suddenly no control and had 110 mph missiles slowly nosing into the ground.
