As i'm looking to upgrade to dewalt I thought i'd record speed tests on stock setup running lipos so I have something to compare it to.
Look at my gps speed test, with my new dewalt 12v and 18/68 gearing
Summit, dewalt 12v, 18/68 gear, T-bone skids
MINE ARE FASTER THAN GPS!!!
Strange how mines faster in lower gear but slower in high gear than yours, plus i'm running lipos as well.
My guess would be that the grass is slowing you down a bit more on your high gear run. Check it again on road
14.4 Dewalt & Misc. el-cheapo mods
Balance your wheels, lower your pushrods and tighten your springs. Unbalanced wheels will slow you down. Lowered, your axles work at easier/straighter angles. Stiffening the springs will keep your butt from dragging on the ground and give you a harder launch. This are a few tuning tricks to give you a little more top speed.
I almost forgot... Get some Lipo's. You'll have more acceleration, more speed, and more playtime.
PM me for help converting your Summit to brushless
Thanks for the info i'll look into those bits, oh and I am running lipos as per my OP "stock setup running lipos" and as per the intro text to both videos lol
