you are definately in need of a laxative.

If you'd ever flown an O-200 you would realise that you are wrong.
did you know that at 4,000rpm they deliver 150hp.


What diameter of prop can you turn at 4000 rpm?

A Volkswagen is NOT a good direct drive aircraft engine because it
produces good power at 3200 to 3800 rpm. But it's a hell of a lot
easier to put a redrive on a VW than an O-200.

What is TBO of a O-200 at 4000 rpm?

Except for a very esoteric and crowd-unappealing, masturbatory sport
of F1 air racing no one is going to turn a O-200 at these RPMs. So you
are talking smack.

so I gather you find Formula 1 aircraft too hot to handle and the
engines too difficult to understand.

there is no TBO at 4,000 rpm and I never suggested there was.

I dont know where vw engines come in a discussion on the new O-200 LSA
engine but from personal experience both engines perform quite well as
direct drive powerplants with two and three bladed propellers.

sorry I missed a question there brown eyes. what diameter of prop?
dunno. ask the formula one guys they've managed to find suitable props
for nearly 50 years now.
when you're next as oshkosh have a look at wittman's hangar wall.
there were rows of them in the last photo I saw of the wall.
