velcro battery strap
 

So far I am not happy with my latest purchase of an axial velcro strap 16x200mm part AX30041. The guy at the lhs said that is what he uses in his slash. So I put it in my blitz. And I can not figure out how to get it tight enough to hold my gens ace 40c 2s (so slightly taller than a "standard" 2s). It moves around like crazy. Is there like a diagram or something on how to install this 2 piece velcro strap? I feel like an idiot having to ask, you would think it would be more simple than it is. All I wanted was a single piece that loops around the battery and holds it firm. This stupid adjustable crap doesnt hold it firm at all.
