Deja Vu FB! I've seen that before, but don't remember how I got there.
Certainly some very creative things have been done by man over the centuries... all it takes is a little time & some determination to make it happen.
I thought I had it set at 30bar Kalle, but I noticed here lately that the gauge is reading 35bar.
Keeping it planted is all about finesse.
When I 1st started learning with the rc excavator more than a decade ago, an ol' pro come to see my hobby & within a minute of me showing him the model's ability, he said "you can quickly tell who's good & who's not by how much the tracks move up & down while they're digging".... that's something I took to heart from then on.
In the vids of your's I see, you spend a lot of time sitting on rocks... where as I am flat footed on clay & the tracks will grip much better.
