Mutilator

The truck has been completely rebuilt. Instead of changing all the diffs, I only changed the center diff with a ravager diff with 51t spur. To stay away from gearing too high I decided I could keeps rpm's low. I have 3 options:
- Neu 1521 1.5y @ 8s : 31080rpm
- Medusa 80m1100kv @8s : 32560 rpm
- CC-Neu 1518 @ 5s : 33300 rpm

I'm not quite sure which way to go yet....

R u racing or bashing? If racing 5-6s is more than enough. I m using neu 1515/3d on 6s 5000 zippy, 50 slip diff n 16 pinion which gv me 37mph.

8s will be too heavy, 6s 5000 is already heavy.

Btw my car is a x1 CRT with x2 gearing.

Bashing only. Why would 8s be too heavy? I'll probably run 8s3000mah if I go for 8s. With the Neu 1521 on 8s and 13/51 gearing speedcalc's output without ballooning is 39mph.
