So i thought I could make it work, Plan on hitting TQ tomorrow night for my fisrt run. Hopefully I can get the spur/pinion I need from there to put them in real quick.


Redbull I sent you a PM.
Seems most 17.5 racers are recommending something in the range of high 3:1 ratio. (3.9:1) thru (3.7:1)
Look at the last page of your BD7 instructions
There is a gear chart
