A little update. I haven't had too much time lately between vacation, work and a huge ice storm.
I mainly worked on the drive train of the carrier. I bought a 540 motor with a reduction case attached (No, I did not make it myself, i am getting lazy), which fits perfectly.
then i did a test run and it worked great with the 2 speed auxiliary gearbox, but it lacked a low low speed, it just went too fast for moving it fully rigged.
So I decided to add a gear box which I bolted to the existing one, giving the option of an extra 1 in 4 reduction and a total of 4 speeds. That should do it! It is almost ready, most of the parts are there.
