Yeah I have done every mod one one of my zipzaps..which includes the pcb..swap...but I got tired of the stupid clone controllers...so I decided to do every mod possible...to the stock pcb...and success...I can run 3.8's no problem..and boy is the thing fast...so here it is a list of all the mods:
1. Dual battery go it to fit inside the chassis even with the stock (huge) pcb without fliping the pcb over.
2. THe no reverse mod with switch...the switch kinda sticks out and is pretty ugly but I love the choice.
3. PCB mod...with computer jumpers...so I can choose too
...hmmm guess the car doesnt have as many mods as I thought...and the body of the car has been changed I added a "boddy kit" the the whoile thing.
If you woiuld like to see pics tell...me all I have is a scanner but I think that is good enough.
