RE: Spektrum DX-7
I finally got up the nerve to try the Spektrum AR7000 in my 1/4 scale model of the Hanriot HD-1. Part of my concern was the aluminum cowl and the aluminum skin (.012 litho plate) that covers the front area of the fuselage where the rx is located. The main rx is under the pilot seat and the satellite has a 12" extension and is back about where the 5 is on the fuselage side. Worked flawlessly. I was careful to watch the rx battery voltage, and I also had one of those little Spektrum voltage protectors installed. Previously I've flown the model with a JR 10 channel dual conversion PCM rx, but with all those flying wires there were always one or two glitches each flight. The Spektrum was rock solid.
Thanks to all who contribute their experiences to this thread, as I tried to read most of the reports and learn from others to minimize the risk....
