I don't know about that Chuck. My Phantom on Fastrack was a lousy puller with the single motor as well. It also had really rotten speed control, basically stopped or warp speed! Adding the second motor gave it much more controllable speed as well as way more pulling power.
A motor in the front is the worst place to put it, and it totally escapes me why if it would fit, they didn't put the single motor in back!
