ON/OFF
The kit comes with a bracket to mount the switch above the steering servo. Alot of guys dont believe in switches, and I know alot of guys that use some sort of switch. Download the manual and parts list from the Mugen website, and order the parts tree that comes with the bracket, and you can find the switch at any Hobby Shop. Its the standard switch that is used on most cars. The bracket holds the switch and the transponder mount. I use it and have had no problems, and this is my second season with the same switch.
