RE: Futaba fasst 2.4ghz signal loss
If you put the Hobbico Voltwatch on your plane, it will provide some good info. Make sure it is plugged into one of the spare channels on the receiver (not on a Y connector) and look at the display as you cycle the sticks. If you see the LEDs bouncing around as the sticks are pushed, you may have a problem as that means you are getting voltage depressions on the receiver bus. If this happens, you are in need of heavier duty wire, better switch or batteries with less internal resistance. Also, if you check the Voltwatch at the end of each flight before turning off any switches, you will have a good idea of the state of charge of your on board battery. The Voltwatch is almost as good as having an ocilloscope on your battery bus.
