...That is one case for direct drive engines, the lower revs do make less disturbance IMO.

... and a side-valve engine would be naturally rev-limited!

 

Prop noise is a challenge. I like ducted fans, and I'm toying with a channel-wing design (drawn on the back of envelopes) which would keep the people underneath happy.

All the best designs start on the back of a napkin etc!

 

You should start a thread with the idea, I am interested for one.

Yep Bex, I should. I was in a similar discussion on another forum months ago, but I've misplaced my drawings.

Napkins are a bit upmarket for paupers like me. I have often got carried away on paper tablecloths in the sort of restaurants I can afford. One night I was midway thru a complex design when my other half pointed out that it was a real, dinky di tablecloth- and biro doesn't easily wash out. Cured me.

...but I'm not your Mum. Well I can be for $100.

The scary thing is that 2 members agreed with this post. Got your $200 yet Bex?

A niche market I would have thought, but then again, humanity is a broad church.

We have all done that...... except in my case it was a fountain pen....
