Hi YHR,
Nice setup, again
You could also build a "standardtigerpantherbox" (new word) wich includes battery and electronics and use a common quick connectors to motors, speakers and switches. Then you could switch between your models.
My second Tiger triggerd this idea, the El-Mod stuff is wery nice, but Mrs. Jakeands budget for such equipment is limited[sm=tired.gif]

Jake
