This looks like a fantastic project. I priced everything out and it comes to ~$300 each even cutting some corners (I have a pair of trucks and extra wheels, free decks, no 3D battery or ESC box, etc.). The batt, motor, and ESC are big parts of the cost. Have you used any alternatives that might save $? Just checking!
Great idea w/ the tripod, Melarky. One important caution is no matter how loose the stump gets, please do not attach it with a strap to a trailer ball as in the photo. Even with a 2WD truck you could put way more lateral force on the ball shaft than it's rated for. If broken, the ball turns into a potentially lethal 2" projectile! Google this for some interesting photos and x-rays... Instead, attach the strap or rope to a secure point on the vehicle frame and live to fight another shrub!
