So i now have a semi stock 3905. The only consideration for this post is the Jumbo Kong tires. And maintaining lots of torque to push them.I'm currently running the twin Titan 550s and like the way they pull. So my question is what would be the best brushless set up? I know I'll have to go to lipo. Would twin 540 brushless work? Is that possible (ESC)? I would like the beast to be water proof also. Can the drive train take it? Any insight would be helpful.
