Thanks, so would that motor be equivalent to the reedy 3300Kv? Reason I ask, is my Dad and son have a t4.1 rtr brushless with the same reedy motor and we all run in the same races, so I'm trying to keep everyone in the same speed category, as best I can at the moment.

We will need to upgrade their motors as well...will this castle motor be OK for the t4.1, or is it too much for it?
