3.0 - 3.8 in a Zip with Bit PCB board doesnt Go?
 

I dont know why a 3.0 motor in my ZipZap doesnt go without a little push. Only thing I can think of is that the ZipZap is a little heavier than a bit. Anyone else have any other opinions? I have a feeling the 3.8 is gonna be useless unless I resolve my dual bat mod issues, which by the way everyone seems to be clueless about based on the lack of responses on this board.

ur 3.0 is prolly a lil too heavy, so it needs a lil tug before it can work.

Heavy? I mean why would it work in a Bit and not in a Zip with a Bit PCB installed? Could it be the weight difference of the cars themselves? Thats the only thing I can think of, aside from the battery.

I should be getting my 3.8 tomorrow and I have a feeling I'm gonna be disappointed.

Get ready... The 3.8 has less torque than the 3.0 so unless you can resolve your dual batt. issues, disapointment city next 5 miles...

I remember your thread, and my advice would be to take it all apart again, start from scratch, and test everything...
I wish I could help more, but that's what I would do if I were you.
