Yes, i run this exact combination.
The motor is the same base motor as the Orion.
The timing should be changed as the manual tells you. I am not 100% sure of the reasons, but it is something to do with the speedcontrollers and the timing of how they work. You should also change the timing of the orion motor - but they don't tell you this.
Yeah use the LRP sonsor lead. The GM suplied one is slightly different on one end, and hence won't work. It's the same with the Orion motor.
