The other thing to consider is KV - are you running a 3S battery (11.1V) or 4S (14.4V)? The large 2000kv motor would well suit a 4S setup, but might be a touch slow on 3S (though it'll have massive torque anyway, so can be geared well up if you can get the right gear ratio to fit). 4S setups, it must be said, are pretty hot - it's a lot of power!
