Default RE: Shrike flight report

Reza:

“Tractor” means the prop, mounted on a normal rotation engine with the prop at the front of the plane will pull – it is loaded in traction. In other words, yes, a “Tractor” prop has the blades pitched for everybody’s normal engine in a normal mounting.

A “Pusher” prop has the blades pitched opposite to the tractor prop, and when mounted on an engine turning in normal rotation will push toward the engine instead of pulling away from it. At the same time, a “Pusher” prop mounted on an engine with reversed rotation becomes a tractor prop, it is just turning the “Wrong” way.

In other words, you need one tractor and one pusher for counter rotating engines.
