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

[MetalMan]

My Savage broke the magnet of a Feigao 12XL on 10s2p A123 geared for 60-70mph, but my KB45 10XL has been pushing the truck just fine, doing the same thing. It doesn't even get as hot

I have a kershaw design motor mount so its way out of the way of the battery. And drilling a new hole for the kb45 motor isnt a problem nor is turning the shaft down to 5 mm for me. The thing I am worried about the most with the kb45XL is will the can fall apart without a clamp like a feigao motor does during a crash?

If the kb45 8XL is more powerfull and runs cooler that sounds what I want especially on a big heavy 13lb savage thats locked in second gear.
