I have the Traxxas receiver pack in the middle.

Originally I wired 6 AA NIMH Energizers for the remote start power. But they barely turned the motor over.
Lowest cost was the goal. So I used the stock NiCad from the controller.

The Micro Switch came from Radio Shack...$2.99.

I modded my engine a couple months back and it screams. The night of the Remote Start video my Jato was radar gunned at 68MPH with the 22/56 gearing.
This remote start is only temporary.
When my starter box arrives it's bye-bye to the remote start, EZ-Start system and a lot of other weight.
I am looking break 100MPH with the 3.3 motor.
