R/C Calculations Updated?

[InsaneRC]

Wow seems the R/C Calculations was updated but it is still missing a few stuff.

does not have the Ultra LX-1E kit

For the:
Front/Rear Differential Gear Ratio
Transmission Gear Ratio
tire diameter in inches (which I was able to find)

Has everything else to calculate but the things listed.

Running a Ofna Ultra LX-1E w/ a HobbyWing 2350 Brushless motor w/ 9/51 and idk if thats to fast or too slow. I have other pinions but Idk what my front/rear diff are or the transmission gear ratio is.

well thanks for the help on this
