Ya, I say to watch electrical interference but I have a whip right beside three servoes, ,a battery and a receiver in my P-40 and have never had a problem. The wires for the elevator and rudder run right along the bottom of the fuse beside it. I guess my point was more to check it over really, really, really well before you fly it. If you don't have any interference there, then you more than likely won't in the air. This is my experience and I would feel comfortable installing one inside the fuse of any aircraft I have and will have in the future. Like I say, just be thourough and you will be fine.
