Yea I Think Im Goin To Scratch The Kb45 Idea And Either Use A 10xl Or Just Spend The Cash And Get Another 1521. Because Its Goin To Be Work The Kb Is Almost.25" Bigger In Dia Than The Neu And Almost .35" Bigger Than The Fiegao And Then If It Does Fit I Have To Worry About Pinions.
A 10xl on 6s should do fine. I have an aveox motor that I will use on 8s in my flm savage. Still need to buy the batteries, going with flightpower 3700 4s packs in series. The motor is 1200kv, and about the size of a 1515.
