Hi Art K, Kim , MJM460, propforward , Trevorc !
Thanks for the welcome and compliments !
Trevorc !
About the plan,
I designed it, but there was a little change when I made it, then my friend wanted to change it more to be close to the real engine, so I just based on the engine and changed. I'm redrawing
About the casting : I don't have casting , I make the motor from aluminum pieces
This is a picture of my friend's engine changed when he got it
