I think those motors will be fine. I run four of those type of motors in my conversion but they are 77rpm direct drive. I had 133rpm motors first and it would do wheelies if you went reverse to forward.lol It was fun but not very practical for digging. The sabertooth is way overkill for what you need with those motors but they are very nice. You may want to save it for something else and just buy one cheap Hobbyking or eBay esc for the drive motors. I run all four of my motors off of one HK esc($11US). As Coop said, keep the pictures coming!
