ZAC Project OS .12?
 
Does anyone know if ZAC Project has plans to, or in the past did make a .12 similar to this .21 engine?

Any ideas why or why not?

I did asked before, nope they are not making one. I believe because they are more 8th-centric.

Good powerband.. smoother than the original OS Speed.
The main difference is the crankshaft, which is balanced
