Very awesome to get to get to see this off the bench and moving!

Mmm, counter-steering. Could you set up a way to toggle a mix to also allow Crab steering?
If you don't have any tire scrub on turns, you're already doing way better than fullsize JLG bucket lifts

Originally, yes. Now I'm going to skip all together. Less wiring and the inner motor is able to bog down to match speed.

Crab steer is a must! It should be pretty easy to setup on the radio. It's the feature I look forward to the most when placing stuff with the forks. I'll do a front steer only as well for high speed travel.

Worked on the tilt a bit. Had to turn a bunch of tubes from stainless. It was terrible, but I got it done. These parts were reworked from original design to accept Lesu implements. Less stuff I have to build and some commonality to my small wheel loader.

Progress dump one what I've accomplished while the site was down:

Machine is fully functional now. Wiring is mostly hanging out the side before I condense it all. Hydraulics are really smooth although slightly slow. Since I'm only on 2S lipo I should have a slightly higher kv pump motor. Not going to change anything. Works great as it is.

Did add a step up voltage converter to get a steady 12V for the drive motors. Woke them up and make better torque. Will still swap in a set with deeper reduction.

Crab steer is my favorite feature when placing a barrier inline. A fun little machine

Really looks good, great progress. Am glad to get to see more.

Looks like really good use of the site downtime!

Great looking construction fleet

Thanks guys. I'm really happy with this machine. I've been slow to start painting since it's too much fun to play with.
