So I Have a Muggy Now!

[riverat1540]

I took on a muggy roller on trade for some paintball stuff and think it would be a great candidate for my next brushless creation. cant help but look at the mamba monster 2200 system for this setup on 5-6s but gearing options have me wondering how low i will be able to gear on the pinion with a stock spur due to space issues with the motor and center brace. id like to gear for around 45-50 on this truck. also wondering if it is best to run mechanical brakes on a truck this size or just use the electric brakes get the slipperential, im leaning towards the slipperential if it will fit but could use some input. and any tips from previous build would really be appreciated
Thanks
