Thanks for the video.

Looks like it's hard to keep a slow steady crawl and could beneifit from a 35T motor. At least for getting better crawlability.

Using front locker instead of differential may be better

If you have one laying around, throw an Axial 27 turn motor in and find a happy medium?

Hmmm...Good idea. Have a 27T Axial and a 35T Tekin "laying" around. Time to do some testing."thumbsup"

I'm kinda between those two options with an ESC that's 3s capable.

Steering looked really weak as well as the crawl ability seems less than what I was expecting. At least for what I was hoping for with a "low" gear. Not bashing - I just know that would have been cake with my current rigs.
Thanks for the vid - more info for my decision matrix! :)

The bec output is only 1A max. so you can image the servo strength
