Since I started the thread I guess I could theoretically delete the entire thing, does that answer your first question. I just wanted you to have your own thread as this ones title is not drawing you the attention to your questions that you apparently are looking for. The title is about an M41 which is not as popular as WWII tanks. A new thread started by you indicating the type of WWII tank you have would be far more beneficial. Folks here love WWII tanks a bit more.

The ratio you are asking about has already been answered above, go back and re-read the thread. If you cannot figure it out from what has already been posted then you might be in the wrong hobby. R/C tanks are a bit more challenging then cars/trucks and you will have to problem solve on your own far more. Sorry but its the truth, there is not a lot of hand holding with tanks.

You don't have to be arrogant about it.......I have built R/C Helicopters since before such thing as a drone existed.....I have built competition rock crawlers for drivers who have won major events............I have scratch-built over 20 airplanes, both multi and single engine.............but the nature of these tanks is different.......pre-formed.....one must get the parts for something specific.......new to me.

My question was regarding the steel, as opposed to the "metal" transmission.....I did not now if there was a difference beyond materials......that's why I asked.
.

I always enjoy sharing my knowledge of my own chosen hobbies with others.....take additional questions as a sign of interest and desire to fully understand.

But then I am not you.

Apologies for intruding into your domain, rest assured it will not happen again.
