Hi Richy
Not sure on 13.5 motors as i've never run one.
But for servo's, obviously the faster and higher torque you can afford the better. Speed wise, most people will look for around 0.1s or less for 60 degrees. Torque wise, 8kg upwards would be fine for offroad. If you plan to only run indoors with a slower motor then you can obviously get away with a lower torque as there won;t be so much strain from high speed high grip sweepers etc.
Oh, and metal gears are a must!
Something like a savox 1258 is ideal.
