Hi!
Britbrat...those figures are just in bench figures ...say nothing (or very little) how the engines behave in the air.
My experiences are based how engines react when flying them...in the air.
I agree that there are small differences among those .40-.46 engines mentioned ...but not anything a newcomer with a high winged trainer would notice. But for an experienced flier in a fast low winged airplane ...yes there are differences!
That's why (nearly ) all Q-500 pylonracers over here use the Webra .40 GT
Which I don't like being the Swedish MVVS importer[:@]

Best regards!

Hi Jaka

I agree that in-flight engine behaviour is different from the static situation. I also agree that if the engines are over-propped, the differences will be muted.

However, when more optimally propped, the differences can be quite significant -- even on a trainer. Those differences can mean either a dull, uninspired performer, or an interesting and spirited plane to fly, despite being a trainer.

I guess that we just have different opinions in this regard.

Cheers
