Default RE: Is An OS 55AX The Right Engine?


ORIGINAL: DarZeelon

Real planes don't have such power...
Let's compare a high-wing aileron trainer, to a Cessna 162 (Skycatcher, the 152 replacement).
This plane powers its 1,320 lb. MTOW, with 100 HP (Continental O200D), meaning 13.2 lbs per HP...

A .40-.46 engine realistically puts out about 0.9-1.1 HP.
Realistic power is flying a 5 lb., .40-.46 sized trainer, off a paved runway, with a standard .12-.15 engine in the nose.

Anything more than this would be overpowering it... Even a standard .40 has a 170% overpower!

That Cessna climbs-out at a 10-15° up trajectory. Vertical??? What the hell is that?


Flying right is power management; not overpowering.
Thanks for the engine lesson! So you do or don't think an OS 55AX is the right engine? Don't think I read that any where in your pst.

Ever heard of Wayne Handley and his Turbo Raven? That was a real plane that had such power.

"Flying right"? I guess all of the 3D pilots all over the world are doing it wrong?
