Update: finally found some free time and got the motors and escs rigged for a trial, looks fine running on no load and looks quite powerful. One thing I noticed,full fwd to full reverse the motor will come to a stop in a fraction of a second (with a big jerk), but you have to give it a reverse command again to spin in rev. Well, I'll see to that when I get the programming card and have everything connected...

Gearboxes almost done, had a problem with the pinion gears which I just couldn't drill through! Dont know what material they were made from, for me its some type of cast steel or similar. Tried with a cobalt drill, no success, so I machined a new face on the lathe, no swarf came out, just a golden powder...tried to drill again, with some success...again golden powder instead of swarf. I bored about 3/4 of the length of the gear and then again, the drill refused to cut any further...like trying to drill a piece of hardened steel.
I the end I found that the gears had cracked the gears are made of some type of steel for sure as its magnetic and flies yellow sparks when ground, like these:

I ordered a new set from a different shop and I'm sure these are normal steel and the hole size is correct so I dont need to drill anything... after that the boxes should be done...
