i am just telling you what the system says. everything is calculated based on the spur, pinion, and tire diameter you type in and the the signal from the sensor. i know how to type in numbers and i have digital calipers to measure diameter, so i post what it tells me, until someone with the Exact same truck does a run and posts a different speed, i do believe mine stands. i also am talking about straightline speed on road with a highly modified truck and a one of a kind custom tranny.

what the system says is fine. getting your motor to actually pull that gearing is the problem. i had a t4 with the novak 5800 and it was not even close to those speeds. i would say 37-38 on 7 cells. http://www.teamnovak.com/Download/ac...pecgearing.pdf look at the bottom, also that is based on 6 cells, for 7 you should gear even lower.

i took the truck out with gearing that pulled 48mph and it ran like mad. i didnt have my recorder in it to check the speed, but i guess it doesnt matter much now as i will be putting my new system in and see how fast it will run.

Okay, here are my Revos numbers:

Motor: Feigao 9L
ESC: BK 9918
Cells: 14 GP
Spur: 66
Pinion: 16
Tranny: EMaxx
Diffs: Revo (same reduction as Maxx)
Wheels: Maxx sized

Guesstimated speeds:

1st gear: A bit more than 20mph
2nd gear: A bit less than 40 mph. But more than 35, I think.

Sorry for the inaccurate speeds. I have no possibility of measuring accurately. But I think those are good guesses.

The temps are fine, I still think I could add a tooth or two on the pinion.
