MY EXPERIENCE:

I have a little .15 sized stick that I kit built. I put a full sized rx in it, so the antenna was way too long for the plane. I routed the antenna on the bottom of the fuse--doubling it back and forth (making sure it didn't touch itself anywhere), and locked it into place with packing tape. I've never had an issue with it whatsoever. I did extensive range checks with this one, since I was kind of scared of it. I had the plane in my dad's workshop, and walked 75 feet INTO their house. Dad was at the airplane checking things out--no jitters, and everything worked fine 75 feet away, through brick and wood walls, with the tx antenna down. So, I flew it and have flown it many times--no problems. I do a range check on it often, but I don't see that it has affecte the range at all. Granted, this plane flies a little closer than the average 40 or 60 sized plane due to visual constraints, but I still fly it quite a ways out--well over 1500 feet away, without incident. JMO. Let the flaming begin....
