Hi All:
I am building an "Oscar Duce" (Push-pull Cessna) and am using magnum .70 4-strokes on it. My problem is that there is a lack of pusher props for this size engine (a few but not many). Does anyone know if there is a reverse rotation cam available for the Magnum .70?

I doubt that you will find a reverse cam. Master Airscrew makes a 12-6 three bladed
prop that might be ideal for your application.

FBD.

reverse props are available. As far as I know, only MVVS (used to?) supplies reverse rotation cranks.

Thank's guys. I'll try a few of the availible pusher props.

Enya can be reversed with conventional cranks and a rotated front case.

..............I've been wanting to say this for ages
So can a rear induction Dooling 29

Downunder, Rotating the front of your Dooling will not reverse its direction of rotation. You have to rotate the back end.

Well I did say rear induction
Not that I'm going to try it because I haven't even run it.....
