Endurance of 5.5 hrs is 17.3 litres/hour. Quite sporting for a 150 hp Lycoming. That is much more than Pazmany claims - maximum of 4.1 hrs but only with the 108 hp Lycoming 0-235 engine fitted.

It attracted a little bit of interest when the first one appeared but …. only 3 as of 2015 indicates its relevance. My last recollection of anything about it was a fatal accident involving a well-known pilot some years ago.

Some pics from my visit to the CallAir Museum in 2013. Glen Call was my guide.

The airplane in your top photo, VH-EGT, came to a sticky end (unsurprisingly).

Interesting to visit the Callair Museum http://www.callairmuseum.org/HOME.html

When last there I was shown around by an old workmate, one of the Call family.

During the pandemic I participated in a global roll rate challenge where we discovered the lies told about aircraft roll rates. Videos of multiple rolls were independently analysed for the steady, maximum roll rate at Va. Often multiple examples of the same type flown by different people. Cessna 152 about 60 deg/sec. Super Decathlon is around 100 deg/sec. Pitts S-2B at 140 deg/sec compared to a figure of 240 deg/sec quoted in a magazine (by myself). Pitts S-2C at 210. The Yak 55 at 110 deg/sec rolls faster than a Yak 52 - nice to roll but whoever claimed "...rolls (to the right) at well more than 180 degrees/second (measured up to 352 degrees/second to the right) ...." is a far worse liar than I was.

"It has been used in international aerobatic competition up to the Advanced level .... is capable of every manoeuvre in the Aresti catalog." Advanced category (and others) has changed dramatically over the years. These days it is extremely hard work to get it through an Intermediate sequence - it is nearly as good as a Pitts S-2A.

I nearly bought one but went for a Decathlon instead.

Any new info within the last 15 years?

Cutaway Eagle.

Yep, good roll rate. 164 deg/sec actually achieved by one pilot here. A little while back a number of aerobatic pilots submitted videos of multiple rolls from which the time from inverted to inverted was measured and the maximum steady roll rate determined. All did it with full aileron at Maneuver Speed. By comparison the Super Decathlon is 90 deg/sec.

Nice airplane to fly. I visited Frank in the ‘80s and he kindly spent much time showing me around the factory with a peek at his new project.

I ended up working for Aviat.

I'd like to fly one https://bevhoward.com/Buecker.htm

Dragging the top of the fin through water like Fred Nicole sounds like fun ... https://sbeaver.com/Bucker/index.php/anecdotes-mainmenu-69?start=5

Somewhere in my filing cabinet I have a manufacturing plan for the SAH-1.

The 242 is a very nice aeroplane to fly.

“ However, if customers register the aircraft as ‘Experimental’, then aerobatics are authorised…” pretty clear.

 Very nice, behaved much like a Pitts S-1 as far as I recall, although I didn’t get much time in it and no aerobatics. The owner had flown it from the UK to Australia and he wasn’t here to get it to Richmond for the show.

In 1988 I flew G-AWPZ into Richmond for the Bicentennial Air Show.
