I'm just getting back into the hobby after about 10 years and a couple of kids. I'm building a Piper Cub and need to locate the receiver battery as far to the rear as possible due to being a little nose heavy. The location I'd like to put it won't allow the battery to be wrapped in foam. Does the receiver battery absolutely need to be wrapped in foam?? I was gonna use quality velcro to secure the battery. It will certainly be secure. A crash that would dislodge it would be fatal to the plane anyway. My question is about the vibration factor. Does a quality velcro (thich fuzzy side) provide the vibration protection needed or for that matter does the battery need vibration protection at all? [sm=confused.gif]
