RE: Diamond Dust and RF interference?
Rudeboy,
Is there a chance that when you are diving that you are sucking air from the tank which seems to cause the engine to go to "idle"? I have had that happen in the past. With the nose down, the fuel falls to the front while the clunk remains in back of the tank. Does this happen in the beginning of your flight when the tank is full or only after you've flown a bit? With the way that these engines gulp fuel, it dosen't take long to form an airbubble in the tank unless you are using a bladder tank. The "glitch" could be caused by the abscence of RPM's acrose the flying surfaces due to fuel starvation. I would not be too quick to call this radio interference. I never had any trouble with my Dust like what you are seeing.
