Ok. Sorry for not updating more recently, but we've been busy around here testing out a few products and just playing with our cars!
A quick Update on the sumo. We burned out a motor, destroyed a pinion gear, and melted a plastic bushing or two. This was sad, but expected when you drive any rc through mud and sand and ponds especially an itty bitty like the sumo.
No worries though, we've rebuilt it, and now it is better than ever!
Here's what we did:
We replaced the motor, we put all new gears in it, including differentials, and we tossed out the plastic bushings and put in bearings. I had a video, or thought I had one, of us doing the work to the truck, but, unfortunately, it didn't turn out well at all.
Anyway, after the work was done the truck is better than new. From a standing stop it will lift the front off the ground now, which is awesome. The wheel wobble is also totally gone. It is almost like playing with an entirely different toy now.
