What!!! Winding gear cranks, is not a big market
do you realize how vast and enormous the crank winding market is, it encapsulates every single industry on earth, every single industry relies on crank gear shafts. This conversation is just getting silly after you said that.
You're trying to turn this conversation into specifics when all i'm wanting to know is why remote control DC motors don't exist on the electronic diy scene. You're giving me anecdotal stories i wasn't asking for, so the answer is you don't know either. You could have saved me alot of time by saying you don't know either.
