Hello Rudi

I don't really think any individual pilot has those figures. Maybe the people to speak to is Aviation Engines, Rotax should have stats on this...?

Hi Duck,

Sorry I have not replied - I've been in France at a conference.

I had a B box with a gear ratio of 2,58:1 and a GeoKilly prop (I think 68 inches).

I replaced this with a C box with a gear ratio of 3,47:1 and a Pieter de Necker prop of 72 inches (not 100% sure about this).

As stated earlier this is a great combination and I am really happy with my Aquilla's performance.

Cheers,

Jonathan

Thanks J, this helps a little. The 68 inch sounds about right and was in all probability 34 inches pitch.
Any idea what pitch the 72 inch prop is? You can always look on the prop as Pieter always stamps it onto the hub somewhere.
