Extra 300 - 300HP Lycoming AEIO 540 - Flown them, they wont quite really hover. Combo of: Plane too heavy, prop too small, not enough HP
The Sukhoi, (350-450HP) with its geared radial engine and huge 260cm MT
prop hovers, especially with the 450 HP
Vendenyev M-14R engine. The geared engine allows the prop to turn slower, therefore you can have a larger diameter prop without the tips going supersonic.
Look a Yurgis hover his:
The American Built Zivko Edge 540 (Lycoming bored out to 340hp or so) is VERY light and can hover too.

It takes a big man to cry, but it takes a bigger man to laugh at that man.
