I think I was running 26/81 but it may have been a 84spur... what you ordered should work fine but I'd say you can go up 1 or 2 before any temp issues. Gearing suggestions are tough cause tires vary in height, tracks vary and there are other varibables...best advise is checking your temps and laptimes for proper gearing. I run GTB w/ no fan, never gotten this motor 'hot' ever..maybe 150degrees after a 10 min run, on a hot day. I could gear higher but it's a tight track and would hurt my infield times.

I run a xxxt with a 5700kv system on 5000 20c, 3800 30c, 5000 20c lipos.. There's a BIG difference in run time and performance between nihms and lipos.. I's strongly recommend the lipos..

My motor rocks on the tracks I run.. Kinda open a little and more long straights where the bigger motor buys can pull away..
