I did it like this on mine.
[QUOTE=necron]Nice Mod. But why go through the trouble of soldering to the circuit board and pulling everything apart? Couldn't you just run a wire to the + and - terminal in the battery compartment and then to a jack? [/QUOTE]
I simply left a pigtail around 3 inches hanging out the bottom of the transmitter to plug the charger into. I did the same to the batter pack on my T-Maxx too. The batteries I am using are the sanyo nicds. They seem to be still working very well and were installed in my transmitter and truck back in 2002. I have to say the way you did it is a much cleaner look. Very good job on your how to do it. :cool:
