Team Associated’s B5 and B5M include little blue thumbwheels that you unscrew to remove the battery. These work great but could us a little pizazz. AVID RC has released an upgraded set of thumbscrews that are half the weight of the original screws and come with o-rings to keep them from loosening up.
I’ve got a set on order; I can’t wait to give these a try! They look cool!
AV1048-TH-B5 B5/B5M Battery Thumbwheels – $15.00
