For those with an inclination to the obscure and the unloved, here is a real beauty - in my eyes anyway! Hope you will be interested to follow.

The GAF GAFHawk-125 is a one-off utility plane designed and built by a drill component company back in the 80's. And yes the designer had a plan to take on the world of utility aviation...  a dream which did not eventuate...  but sometimes having the dream in the first place is what counts.

The plan comes from Takashi Sugihara and was published in "P-Tech" - a newsletter of the Shonai Peanut group of Nagoya. It's been on my 'to do list' for a while. And it's time!

Here are some pics of the original to get things started.

cheers
Tim

I think that may be the weirdest hybrid of Short Skyvan, Lacey M-10 and Pilatus Porter I've ever seen.  Nevertheless... looking forward to seeing this one come together.

Tim,
       You have an ability to find unusual projects. Did this aeroplane lead to the Nomad? There seems to be a cerain resemblance. Week 3 of the lockdown has been busy it is just that I have to get busy with the camera to show the results.

Lurk, Kaintuck, Ricky - no, not related to the Skyvan, Lacey or Nomad - nor was it designed with skydivers in mind - and yes VintageMike, it does prove that a tin shed can fly!

The design process included a flying half-size prototype put together in the workshops of Hawk Industries in Yucca Valley California from a 1956 Piper PA-22-150 Tri-Pacer and made to look like a miniature version of the GAFHawk design (see pic attached) to serve as a testbed for the GAFHawk's development. The aircraft was appropriately named the MiniHawk, and first flew in 1978.

Based on the lessons learned from the Minihawk, an actual GAF-125 prototype was built, and registered as N101GH on 9 December 1981. This much larger aircraft made a successful first flight on 19 August 1982, powered by a Pratt & Whitney PT6A-45R turboprop engine.

So yes Lurk - same engine as many of the Turbo Porter aircraft! Well spotted.

A little bit of progress with the fuselage frame - yes I can see the Lacey likeness. If only it had about double the wing chord!
cheers
