Need help with tricell

[Zephyranthes]

I want to do a tricell mod with 2 cells in the chassis, and one out the baack window. Can somebody show me how to wire this up and how it will fit?

You gotta move the normal positioned batt back toward the rear of the car a smidge. take out the metal tongue that contacts the bottom of the motor, and start cutting plastic. Solder the fwd wire to the heat sink. Then you gotta make a lil' room for the 2nd cell in front of it.
