04-06-2009. Due to unpopular demand I have added a second clue below.
Same object - different direction.


Pekka Tammi was a student at the Polytekniknikkojen IlmailuKerho RY, (which is a longer way of saying PIK) where with a bit of help from Ilkka Rantasalo and Raimo Nurminen he designed a glider to meet the recently changed 15m standard class rules (1971 - 72 we are talking here). This included the use of water ballast and wing flaps. It is the wing flaps/brakes that make this glider so different from most which tend to have what are generally referred to as Schempp-Hirth wing brakes and separate conventional trailing edge flaps. The Schempp-Hirth brakes pop up out of the wing surface (sometimes below as well) somewhere about the wing spar region of the wing. This destroys the lift over that section of the wing and increases the drag and therefore the rate of descent. The PIK on the other hand has trailing edge flaps down to about 40 degrees and beyond that - down to 90 degrees are barn door brakes. With the brakes so far back on the wing the centre of pressure moves back when they are deployed and the flying attitude changes to very nose down.

De Havilland DH60M (Gipsy 11) , c/n 1542 , ZK-AEJ, often referred to as "The Racing Moth" has been cancelled as exported after being advertised for sale some time. The Beech G17S ZK-MOE (c/n B-14) and the DH89A ZK-SWR (c/n 6853) have also been advertised.
ZK-AEJ has an extensive history which I have listed below.
I don't actually have any really good pictures of it, but these three will give some idea of its radiant beauty.

Following my previous post on Nieuports in New Zealand, I contacted Ian Sowman of Napier who built this Circa Reproductions Nieuport 11 ZK-WWI, which I think completes the Nieuport replicas in New Zealand. Thanks to Ian for the photo. As you can see, this Nieuport is different from the others as it is wearing a German colour scheme. This is because it is actually a replica of a Siemens-Schuckert D 1b, which was a German copy of a captured Nieuport. The original D 1b differed from the Nieuport in having the top wing set around 100mm lower, and having strengthened centre struts. The original also featured a Siemens-Halske 7 cylinder rotary engine that drove the propellor in the opposite direction of rotation through a gearbox that eliminated torque reaction. Ian's aircraft is powered by a Rotax 503. The colour scheme is modelled after a scheme worn by a similar replica in the USA that is part of the Kansas City Dawn Patrol (but that is another story).
Phew !
So if it's not an F15 airbrake - What is it ?
