fit a Lipo into a mad rat
 

I have a lipo and the lipo i just bought is somewhat too tight and a little to high for the battery tray holder is there a way to hold it down

Put some washers under the battery posts. Fit some longer screws. Obviously you will have to clamp the posts with a pair of pliers when you tighten the screws up but it should raise the battery holder up to fit the battery in. :thumbsup:

Velcro also comes in very handy for an application like this.:thumbsup:

Thats brilliant I have plenty of velcro

+1 :thumbsup: this is better than velcro, that can still come apart in a big crash and if connectors make contact with something they shouldn't "Expensive repair bill" :thumbdown:
