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

Yep, 11xl would be the way to go on 6s. I have the same setup and will be using a 14xl on 9s or 10s.

I take it the big kb45 8xl 1700kv is also too hot for a 6s setup???

Is a 11XL and 6s setup going to be faster than a really fast nitro engine? With my previous setup of 5s and 7XL when it wasnt cogging which was 99% of the time I could tell its power would totally destroy any nitro engine out there.

I plan on sticking my cc phoniex 125 esc and feigao 7XL in my jammin buggy and using mechanical brakes on a 4s lipo setup, hopefully that setup wont be too hot and work good. The 7XL with 14 gp3300 cells worked fine with the phoniex in my savage it just wasnt all that fast, but my buggy is alot lighter than my savage.

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.
