When the Whirlwind's slats were tested at the A&AEE, it was found that when the slats were locked shut the take-off and landing characteristics remained the same, while the aircraft was more pleasant to fly at speeds during which the slats were normally open:

Crumpp, you need to take some drawings lessons :rolleyes:

It was cool to fly over that pretty countryside though...Crumpp what engine, a Lycoming?

I prefer this one, showing the glorious NZ countryside ;)

You went through all that trouble instead of just showing me a scan of a pilot's license? the aircraft in the first video is not pulling high G so no wonder the slats are quite gentle.

Since you asked, yes intro flights are probably much more expensive in the UK than in the US, if you want to fly with me in a Stearman it will cost about £360 per hour, I don't remember what we charge for the 152's or warriors but it's around £150 per hour.

Heres the vid of me and fruitbat in a Stearman taken from that GoPro camera on my head in my avatar pic, check 14:30 for the 'hello Crumpp' and 17:30 for some basic aero's.

Heres a vid of me flying the Learjet, 2008 fresh back from Dallas and doing my 6 cirquits to finish the type rating.

Very cool. Here's me and Riley squished in a Spit cockpit.....

Sigh........sayin' nuffin.

Thanks for this

There is a reason why I am not a commercial artist, LOL.

Here is picture of my hanger, these are my planes....sole ownership....

Means you are alone on the bills too! ;)

Both are fully aerobatic but the Thorp is not a good platform for it. It is too slick and you really have to pay attention to your speeds when you point the nose down.

The Thorp is a good cheap, fast, and fun to fly cross country machine. It has a Lycoming O-360 with a Hartzell CSP. It is IFR, four place, and a traveling machine.

The Extra 300 is my sky cutter. It has a Lycoming IO-540 with an MT propeller.

Back to the thread....

Looking at all the data and trying to pick averages staying away from either extreme using both Supermarines and Mtt data......

This is the relative turn performance of these two aircraft taking as much data from the Operating Notes and Flugzeug Handbuch.

Here is a Rate of Turn comparison. Rate of turn is the most important aspect of turn performance as it represents how fast the aircraft can swing its guns thru the compass to bear on a target.
