composites vs. aluminum

The rear engine on a 337/0-2 sucks air at high velocity over the
center section of the wing giving bird more lift which of course you
can use any way you want.

Or, if one is looking to "prove" the opposite result, put a model
pusher body in a wind tunnel and then reverse the same thing and
test it as a tractor! g

Actually, this question has been answered.

The Cessna SkyMaster has both a pusher and a tractor engine.
The single engine climb rate and speed are both higher for the
rear engine alone, than for the front engine alone.

The pusher wins!

Ah, my lilliputian friend, not enough air to cool the engine, though, since
Vietnam era 02's all got fried rear engines.

Actually, no. One would have to test without the prop on the non-operating
engine and with the cooling inlets streamlined. With the dead engine prop
still on, it is largely a test on which position has less drag than the
other.

Flew an 0-2 for a year in VN. FAC'd in bird and also used as light
transport to support my Sector FAC's in II Corps.

1.Never lost an engine.
2. Never fried a rear engine.
3. Never heard about any frying.

Have always babied my engines.
If I would have needed to fry one to save my ass, would have done so
and never looked back.
