Radio + motor interference?
 

I have recently returned to the model aircraft hobby. As I was attracted by the electric models and the RTFs. My latest an ARTF is a ‘Superfly Delta’ the servos and v tail mixer came from the supplier of the Superfly. The brushless ESC that is an e-fly came from a local model shop. It has a brushless BM 2408-21 attached, and the battery is a Lipo 2C 1100. I am using the radio that I took from my Wing Dragon 4.
The problem that I am having is that when I check the elevons, with the TX. Left, Right, up, or down the motor blips a few revs. I have also noticed that when I do a range test the range seems to be reduced with the antenna retracted. I normally can get at least 40 yards like this with the Wing Dragon 4, before I get the controls fluttering
I thought that it could be the reduced volts of the Lipo. So I tried the Nimh that came with the WD4 and I get the same effect. Any one got any idea on why this is. I will not fly until I get this sorted.

Check the antenna routing out of the plane. Make sure it is away from as much as possible to reduce the possibility of interference.

Fliprob17. That was the first thing that I tried.
