This uses A Sabretooth 25A On 24v or 12v Weight well over 60Kg! Never missed a beat. It's often down to gearing and design.

if your running 2 24v wheelchair motors on 24v you should be on with 2 of the vtx 40 controllers which are like £85 each or unboxed £66 each

is this going to compete or be pushing any serious weight other than moving itself about
