Yep, Hpi doesn't make a 42 spur to give me the 2.8 that I want. I don't think it is going to make too much of a difference, will it?
 
Stock F4.6 with badlands.

so what are you trying to acheive...top end........low end....and also....what kinda pipe are you running. questions might be crazy at first...but trying to help you acheive that goal.

I like a mid range speed, So I can climb hills but at the same time have a good top end. I am running the hpi polished pipe.
 
i say 16/47 or 17/49. that will keep you in the powerband when climbing hills. the stock savage x rtr with the plastic pipe and stock tires is 17/47....so i say go one lower...because the F motors are good performers with that pipe...you just need a little more on the low-mid side. if you want a little more....get an XL tranny. they have a lower first gear and the higher third.
