The gear has 2steps an works perfekt. It was tested hundert Times in Factory And One Season in mY spitfire. There was no problem with the Starter at all. I don't remember exactly but i Think it was Less Then 40amps. of course i Think mr.kolm did a good Job with that.
The other Systems with brushed Engines, a big gear-rod an a magnetic Clutch i don't like. From Sound an optik this is one ofe the best you can have i Think.
you will see it works!
