The build progress on my new Extra 300 has been a little slow. Nice weather has forced me to go fly my new Chip Hyde Tunnel Vision and man is that thing a hoot. It has aileron's bigger than the wings on most planes. I have been trying to get up enough nerve to do a hand launch from the vertical. Chip swears that I can just hold it by the canopy and apply about 1/2 throttle with on the OS 160 and hover it out of my hand-- this with a plane with 80 inch wing span -- Yea right. Guess there is a reason Chip is such a good pilot. Anyway, back on track, I have a concern about mounting the receiver. I have noticed a couple of photos where the antenna is run to a tube and ( I assume) internally toward the tail of the plane. I am using a Futaba 149 PCM receiver but have concerns about interference form the servos and or batteries which are in very close proximity in the pictures. I am setup for a pull-pull so the only wires running to the tail will be the elevator servos on both sides. I am using two 2800 TBM LiIon receiver batteries but don't know where they will be going yet. I know there is never a definitive answer to these questions, but is running the antenna through a tube in the middle of the plane OK or would I be better off it get the antenna as far away from all things electrical as possible?
