As I continue to learn how to use the program, I can see it's going to benefit the design and engineering process in a big way. Much better than drawing in 2 dimensions and just trying to imagine how it would work in 3-D.
Tonight, I get to pick up my prototype piston, ring, wristpin, and sleeve. Once that stuff gets digitized, I'll have something concrete to base some dimensions off of.
Wow. You are The Brave Man if you try to design RC device called engine in google scketchup. I am not talking you out of it, I just try to immaging how many hours you will spend to design main body of engine, shafts, valves, piston and other small things for motor. I am pretty sure you will be able to check for interfiriences, gas flow, perform tolerances patrol in working temperature conditions, flex of components in working temperature conditions ect.
Anyway-good luck on your project.
I suggest you to contact to MXwrench here in forum, he is moderator for this section-he knows 4 strock RC engines as anybody else and I know he preformed a lot of development on them
