not plans (but need help)

[zig 2007]

im in process of designing a micro v8 (air powered of course) and cant decide on what type of valving to use. a pushrod system would be ideal for scale but to complicated i need something small and not to complicated
please help ???

Just a thought, have you looked at a rotary valve with slots cut into a shaft for the valve timing?

Not sure what makes the pushrods too complicated?

You could also make an overhead cam system, but unless its DOHC, which means making 4 cams, you'll still need a rocker system. The rotary valve idea is probably the simplest.

You could always get the plans for this Guys radial engine (the Halo). It uses a push rod system and modify to suit to what you are building.
