70 and beyond?

If I change the pinion and spur gear to the 31/76, and use this battery...http://www.amazon.com/gp/product/B0027GEY9S/ref=pd_lpo_k2_dp_sr_1/189-6999729-0046764?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=lpo-top-stripe-1&pf_rd_r=0JA4BBPA1N9WS8AM003X&pf_rd_t=201&pf_rd_p =486539851&pf_rd_i=B002C219G8.

Can I still reach 70 and beyond mph?

Rustler VXL is the truck! Sorry!

Not 100% sure on that but for an idea I run a vxl 2wd traxxas slash with 31/76 and use a 3s 25c with anaconda tyres and reach a gps reading of 64mph I am going to try altering the tyres to a jayco foam set up and fitting a 56 spur from robbinson racing then starting with a 20 ppinion and working up

for sure, there are a lot of videos out there of guys going over 100 with their rustlers :)
