I have seen and heard of a few guys..not going to mention names...were having strange intermintent issues with apparent RF noise.
swapping rx and transmitter module did not slove the problem, but when the Antena was moved outside the plane, at least half of it anyway, all
problems went away!.
I hope to have my Silhouette IV Electric in the air in about 3 weeks, and i will run the antenna out the bottom in an antena tube on the bottom of the plane.
Just my observations
