They look pretty good, but with that length you might have interference trouble with the airsoft unit in small tanks like the P3 and the StuG. But if you don't have issues there it should be a vast improvement over what's currently available, depending of course, on PRICE. If you can bring them to market at prices competitive with what's currently available you'll have a real winner here.

Excellent engineering, I have always wondered why no one else has done this, as planetary gears have many advantages, increased torque is one of them. :thumbup:

Cost while it turns out high, but is cheaper than eto and modelspiegel. The bulk of the cost goes to the CNC production of the hull. I need to save money to buy your CNC machine :) Then it will be possible to reduce production costs.

Lately gear boxes are on my mind and I can see you done a great job.
Well done.

Hi Kostyanchik,
Rather than the huge outlay on machining the individual parts of the frames, have you considered 3D printing the parts to drastically reduce costs?

I did not consider the possibility of 3d printing, because the plastic case will have a weak stiffness.

If printed correctly they should be OK. You'd also push the bearings into the plastic, so the load should be spread nicely.

He provides the shafts, gears, bearings etc via eBay & gives the frame STL files away for free on Thingiverse.

Hello,
looks great - well done!

Much more better than the new ASIATAM gearbox.
Absolute poor quality:
