i just got a ZZ and didn't like the controller. too small for my large hands. i have just about every tx there is, so i started trying them out to find one that worked right w/o changing anything on the car. i lucked out. the 2nd one i picked up was one of my nak's. it worked perfect and i got about 5-6ft more range. much more comfortable. then i wondered if i could charge the ZZ with it. it worked. in fact even when i dual celled it, it worked great. the ZZ doesn't fit in the charging space, so all i did was set it on there and hold it with my thumb. no snapping it on, no trying to get it to release. just gently hold it there, and you're ready to go. longer run times too.

i need more ZZ chassis.
