Gearing??
 

Anyone know how any of the new e-revo's are geared with a brushless motor in it?? thank you!

depends on what motor your running and what voltage... gear it for about 40 or 45mph..

well im just running the VXL motor and speed control but its running super hott! and the gearing is stock at 68Spur and 19Pinion. I just dont know if to go higher or lower in what spur or pinion or both.

what batteries are you running?

its because thats not enough motor to be pushing the truck, you need at least a fiegao, or medusa is better, neu best

2cell 5000 lipo but 2 of them then a mtronics speed control with a vxl motor.

4s total or 2s2p?

This setup will not give you longterm success - Read some more posts re typical setups for 1/8th scale

4 sell all together

you need a bigger motor...

what motor would you put in it? and what speed control handle whatever motor it is?

hmm lots of choices
Feigao 8-10xl
Medusa 36-50 or 36-60
Neu 1512 or 1515
Biproducts 3674
KDA 36 74

lots to choose from :D

hah if you had to pick one motor... and one speed control...

neu 1515 1yf
MMM
your current 4s setup.

if I had the choice it would be a MGM 160 esc and a 1527 on 6s :D:lol:
