It has been silent for a while on the thread. The where some issues with my mill, which are sorted out now.
In the mean while I have been working om the electronics and the drawings. I recently finished one side of the tractor and I am now working on the other side.
The first run, still without the recoil tensioned. But the overall performance is not bad at all.
