Just a place holder at the moment.

Basically I'm going to turn a Miles Magister into a gyrocopter prototype  for maritime sub spotting and search and rescue. I also have a story/back story in my head that I may be able to prise out.

I may not be able to finish this one on time as Mrs Mog and I are reactivating the cat rescue shed to take in a couple of Ukrainian refugee cats. (Our house is way too small to offer sanctuary to people so this is the next best thing).

Time will tell.

More when it happens

Hi all

Here's the starting point

20220508_211903 by Robomog, on Flickr

With the fuselage mocked up, ive started to turn the wing stubs into sponsons also I found a white metal scarfe ring and Lewis Gun in the parts box  that I thought would be a nice edition. I feel there is going to be some PSR to come.

More W.3.

The image of the instrument panel shows the grip of the control stick, on all of the direct control
autogiros the control stick is attached to the rotor-hub, which you can see clearly in the photo
of the rotor system.

Nice! I like your Weir evolution concept Jon.

Maybe a first stab at the Weir W.6 design is single-rotored. Then, James Weir decides instead to refine his twin-rotored W.5 of 1938. This enlarged W.6 (II) design was more in line with Heinrich Focke's 1936 Fw 61 (later Focke-Achgelis Fa 61). When George Miles of Miles Aircraft made inquiries at Cathcart about the Autodynamic Rotor Head, James Weir was happy to sell Miles the rights.

Once FG Miles approved the sale, Maxine 'Blossom' Miles undertook the redesign of an M.14 Hawk Trainer III airframe to accept the ARH. Initially, known as the M.14G, the autogyro was later redesigned G.1 (in Miles Aircraft's new 'G for Gyro' category) and renamed Gyromagister (to be in line with the rebranding of the fixed-wing M.14 trainer).

As for the second incarnation of the W.6, the outbreak of WW2 ended its development. Plans for producing W.6s at Abbotsinch were finally abandoned for good in 1940.

Thanks for the feed back guys,

Jon :- The pics will help me decide on the location of the rotor and the crucial positioning of the control stick  ;)

Apophenia :-  a very plausible back story I may need it if I can't get my story out of my head !   ;D

Hi all,

Some more progress made.

I decided that the nose was a little short so I've extended it  about a quarter of an inch which also makes transitioning from an oval to a circular cross section much easier.

I took a closer look at the engine and found it to be, well, a bit "rotary" and to make it more "radial" I have added push rods to the front and I am currently bending some plastic rod to form a collector ring.

That funny construction in the bottom left hand corner will eventually become the head of the rotor mast.

The white platform is a template for the Scarfe Ring allowing me to build up the sides without damaging the white metal component it is lightly glued in place and will be cut off when the construction is complete.

Currently deciding whether to place the rotor mast over the front cockpit or just in front of it. A toss up between practicality and aesthetics  ;D

Thanks for looking..............

Pitcairn PA-39 placed the rotor head directly over the fwd. cockpit.


Kellet used a streamlined mast that put the rotor-head just ahead of the fwd. cockpit.

Thanks chaps.

Jon : -  yea I think thats the way to go, the Cierva  C30 also straddled the front cockpit with the pilot in the rear seat but I can rework it for a front seat pilot. :smiley:

Buzz :- three sessions work there very happy with the result  ;)

Hi all

More progress, .using a template to construct the bulged fuselage under the Scarfe ring has paid off .

by Robomog, on Flickr

It still needs a little more sanding but is essentially complete. I'm very happy with the result

As I have lost the fuel tanks In  the wings I've installed a large belly tank under the pilots to give it some range.

by Robomog, on Flickr

Working on the rotor mast at the moment and I have roughed out an undercarriage solution

More when it happens...........

It is curious that you chip away at a kit bash and it seems to be taking ages then suddenly "whumph" most of the construction is done and its ready for the paint shop.

Here it is with rotor mast and undercarriage complete resplendent with its extended rudder.........

And  temporarily posed with its rotor and tailwheel........

Strangely it is now in the paint shop to receive its camo ......

Make sure to warn your pilot about ground resonance.  ;)
