I have the Maverick Vader variant which has the same stock 980kv motor, i've read that this is underpowered for this car so looking to upgrade. I've read lots of threads on this forum but still can't decide. I've narrowed it down to


SKYRC Beast X524 2Y 910KV - 8mm shaft http://www.robinsonracing.com/catalog/brushless_pinion.html around 14/48?


Leopard 5692 1340KV - 6mm shaft 10/48 11/48


Leopard 5692 1090kv - 6mm shaft


Castle 1717 out of the XO-1 - 5mm shaft


They are all around the same price shipped to here in the UK. I have 2x6s and 2x4s 5000mah batteries which I can run in parallel. I'm not looking for mega speed around the 35mph mark and would like to keep costs down so don't want a motor which requires big upgrades.


A setup that runs fairly cool would be nice, I know the leopards need the motor mount from 7075rc http://7075rc.flyingcart.com/index.php?p=detail&pid=5&cat_id= or kershaw http://www.kershawdesigns.com/MotorMounts-Rampage.html but see the 7075rc one seems to be the preferred choice.


Will the toro or castle need a different mount also? would the toro need to be run on 8s to see any improvement over stock?

I would only use the 4s if you ran them in series to equal 8s. 4s just won't cut it. The vehicle is currently setup as 6s (a pair of 3s in series). The car in factory form will run 35mph.
 
took it out for first time today and clocked 28.2mph on 5s (as only had 1 3s) thinking going up a to 11t pinion and 6s as well.

The stock motor on mine cogs quite badly, I do like the look of the SKYRC Beast X524 2Y 910KV anybody else run this?
 
The factory foams will be short lived. Most folks step up to Baja sized wheels and tires. They are a bit larger in diameter so keep that in mind when choosing gearing.
