Thanks, Casper. I appreciate the reply. I was going to add the 3s vertical spacers and cut a dense foam padding. I also noticed the battery brackets (attached to the TLR chassis) was for a 0.5" shorter battery. Not sure if there is a spacer available, but I guess I could make my own. Does Losi/TLR make one? The brackets allow for a 150mm battery and the battery is 138mm.
