A good upgrade is to get a 300 size motor and 6cells......this setup will get you up too speed.....but of course you will need to find a 300 size motor mount. What setup are you running with that motor now, etc 5 or 6 cells, whats the pinion tooth thats on the motor now.
I'm planning to run 6 cells... pinion not sure yet, having pull the pinion off yet but it looks like I have choices of 10-13T in the box of parts I got.
Mainly trying to rebuild and redo all the stuff the previous owner did. Not too fond with them gluing the batteries onto the chassis....
But I do have a new in package 300 motor mount.... so I would need to find a 300 motor? Would that work with the Spy?
I know a lot of members that used the spy would burn it up when using a 300 size motor, but for me i have burned one up and bought another and it worked fine with that setup. The newer version will handle 300 size motors with no problems at all.
