i use this under my ESCs to prevent shorts. Works great. Also gives your ESCs a softer landing when you smack into the ground :P
ESC Padded Foam Strip
Everything went smoothly with my order, with the product working brilliantly and as expected. I use the padded foam strip to pad my pdb's and GoPros and it keeps them from vibrating and contacting the carbon frame. Shipping was quick but once it was shipped you guys forgot to sign it and put a return address on the back, this wasn't a problem to me, but could be if the package was lost. Good shipping experience, though. Thanks guys!
