Savage on 6s which motor, 10XL or KB45 8XL???

There is a HUGE difference in power output between a Feigao 540XL and the KB45XL . Just out of curiosity I bench tested a KB45/10T spinning a 14/6 aircraft prop , you may not see it in the video but it turned that prop with as much ferocity as a 60size nitro motor

Now the kb should be more powerful than the feigao. However, it uses a 6mm shaft and 30mm bolt pattern for m4 thread screws. That means that it will not bolt up to the motor mount, or use std pinions.

Main problem is the larger diameter, which will most likely cause the battery not to fit in the chassis. I was going to use a kb xl in my savage and then found the motor issue with the batteries. Now I am using an aveox 1300kv motor on 8s lipo. Same diameter as a feigao xl, so my batterys will fit.
