The bells for these Emax motor are a quick swap. I've run Emax on most of my quad since I've been flying. I wish they had replacements for the original "red butts", i have a few i would like to recommission. They were out of the 2400KV so i ordered 2750KV. Same bell just labeled differently. Shipping was fast!!
Excellent product, so glad these are available. Hit a tree, damaged a bell breaking a magnet in the process. I so didn't want to change out a whole motor just to fix the problem. These are quick and easy to change, fit perfect, work perfect. The only other thing that should be in the box are a couple of new prop nuts
