Title: Supermarine Speedfire - A classic fail in one seventy two scale
Post by: Robomog on June 03, 2020, 05:43:00 PM
Hi all

Just a collection of parts at the moment and I am letting myself in for some serious PSR but I have a Basher stylie back story in my head so I'm going to run with it

(https://live.staticflickr.com/65535/49965090336_438f512e2d_z.jpg) (https://flic.kr/p/2j8f9AL)20200602_201642 (https://flic.kr/p/2j8f9AL) by Robomog (https://www.flickr.com/photos/54032744@N08/), on Flickr

Brian had a natural knack of mix and matching kits which I dont possess but I will attempt to build something in his style. The only real departure will be the canopy I prefer mine clear as opposed to his signature tinted on the inside.

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

Hi all

Concentrating on the fuselage first, started with removing any raised detail and smoothing out the rudder,  the nose has been extended a bit with a plasticard plug. I've also been doing some work prepping the wings

(https://live.staticflickr.com/65535/49976938101_b5a1a337b3_z.jpg) (https://flic.kr/p/2j9hSwz) (https://flic.kr/p/2j9hSwz) by Robomog (https://www.flickr.com/photos/54032744@N08/), on Flickr

Once the glue was dry I grafted a section of drop tank onto the front to form the air intake, I was originally going to use a Sabre nose but realised that the shark mouth shape was a  tad too iconic.

I've put the first layer of green putty on, I'm getting to the bottom of the tube and its drying really fast, which is why the finish is a bit rough in the picture.

Post by: Robomog on June 10, 2020, 09:20:14 AM
Hi all

Finsrin:  thought I would extend the nose to create a bit more space as the airframe is quite thin, i have to accommodate the nose wheel and have some wiggle space to jemmy in the jet engine, more about that to come.

Frank3k:  your right it does have a Dora look to it, but no propellor here  ;)

Hi all

Phase one of the PSR complete, I now have a reasonable air intake. The cockpit has been detailed and painted and the canopy trimmed to fit.  The wings are on and set

(https://live.staticflickr.com/65535/49996632406_939ae23c5b_z.jpg) (https://flic.kr/p/2jb2NXy) (https://flic.kr/p/2jb2NXy) by Robomog (https://www.flickr.com/photos/54032744@N08/), on Flickr

The next job will be PSR part 2 fitting the jet nozzles and closing up the fuselage

Thanks for looking

Front end is looking good - I am curious to see how you plan to site the exhausts and place the tailplanes... :smiley:
Title: Re: Supermarine Speedfire - A classic fail in one seventy two scale
Post by: Robomog on June 14, 2020, 01:41:03 AM
Hi Dr.  Exhaust and tail planes will be something like this:-

(https://live.staticflickr.com/65535/50002200831_5b5c01cff0_z.jpg) (https://flic.kr/p/2jbwmfT) (https://flic.kr/p/2jbwmfT) by Robomog (https://www.flickr.com/photos/54032744@N08/), on Flickr

The leading ends of the jet nozzles will be heated and bent down. How I blend all this in is still undecided. Stage 2 PSR approaches  :o

The Speedfire is going to become a little tubby ;)

The model will be built wheels up. Doors for the nosewheel and main wheels will be etched on.

More updates soon...........

Looks like you are going for a bit of a Buckeye look
Title: Re: Supermarine Speedfire - A classic fail in one seventy two scale
Post by: Robomog on June 14, 2020, 03:46:39 AM
Yep definitely looking that way but not intentionally  ;D

With some of my kit bashes I have no idea of how the final product will look. I just start with an idea and totally wing it !

In this case I had a spare Spitfire fuselage and found some  Sabre wings were a goodish fit. Then the back story dropped into my head and away I went.

Still have to blend in all the panels............. :-\

May have gone with a metal tail wheel like the Yak-15 did for dealing with that problem.

There is quite a bit of shielding of the tail wheel if you look closely.

Hi all

Well, after a lot of PSR and achy fingers I'm nearly ready for priming, I just need to finish off the tail planes.

Thanks guys, and now the final reveal

The Speedfire

(https://live.staticflickr.com/65535/50098638076_edf4a6f8c4_z.jpg) (https://flic.kr/p/2jk3BG1) (https://flic.kr/p/2jk3BG1) by Robomog (https://www.flickr.com/photos/54032744@N08/), on Flickr

The Supermarine model 391 came out of the need for another jet aircraft to compliment the Gloucester Meteor and to find an answer to the Me 262 threat. Using captured German plans and data it was decided to design a new swept wing and marry it to an available Spitfire Fuselage.

(https://live.staticflickr.com/65535/50098644536_b9414f4454_z.jpg) (https://flic.kr/p/2jk3DBo) (https://flic.kr/p/2jk3DBo) by Robomog (https://www.flickr.com/photos/54032744@N08/), on Flickr

Because of the narrow fuselage they could not to use the available centrifugal jet engines but instead selected an axial design by the newly set up Prescott-Farage Company, based on captured details of the Junkers Jumo jet engine.

(https://live.staticflickr.com/65535/50098643276_597f32999f_z.jpg) (https://flic.kr/p/2jk3DeE) (https://flic.kr/p/2jk3DeE) by Robomog (https://www.flickr.com/photos/54032744@N08/), on Flickr

The design continued apace, the new wings were married successfully to the Spitfire fuselage, together with new tail planes and a bigger canopy.

The story with the engine was not so good, performance proved disappointing and was plagued with technical faults. It was soon evident that it was producing a lot of noise and gas but was severely lacking in thrust. In desperation the aircraft was hastily redesigned to accept two engines but that meant moving them down and outside the fuselage creating unwanted extra drag.

(https://live.staticflickr.com/65535/50098060583_e3342bd7ce_z.jpg) (https://flic.kr/p/2jjZE2e) (https://flic.kr/p/2jjZE2e) by Robomog (https://www.flickr.com/photos/54032744@N08/), on Flickr

When it came to the flight trials the results were a mixed bag. The aircraft took a lot of runway to get off the ground but once in the air it had good flight characteristics and handled well, however it did not get anywhere close to it’s designed top speed or cruise height. Unofficially dubbed the ‘speedfire' by the servicing crew it was thought this was a bit of a tongue in cheek moniker than a reflection of its performance as it was barely keeping up with its propeller driven contemporaries.

(https://live.staticflickr.com/65535/50098598591_791147f5b2_z.jpg) (https://flic.kr/p/2jk3pXe) (https://flic.kr/p/2jk3pXe) by Robomog (https://www.flickr.com/photos/54032744@N08/), on Flickr

The Speedfires demise came one hot summer's afternoon, ballasted for its intended cannon armament the pilot taxied the Speedfire to the end of the runway and started his take off run as usual. He had probably used up half the runway when he realised the aircraft was not beginning to rise, the engines were going flat out but the extra weight and hot day was robbing the aircraft of lift. In desperation he eased back the stick and retracted the undercarriage in hope of reducing the drag, but the Speedfire would not break from ground effect and he had no choice but to chop the throttles and let the aircraft sink back to earth. Shortly after it passed the end of the runway the Speedfire scraped down the overrun area and onto the grass in what one observer described as the most elegant air crash he had ever seen, fortunately the airframe was well constructed and the gutless engines took the brunt of the impact, once the aircraft had slid to a stop the pilot walked away from the aircraft shaken but unhurt.

This was the final straw for Supermarine, the project was cancelled and the model number deallocated, all paperwork and files were destroyed, in fact anything to do with this project was disappeared except anonymous flight data that was later used on the Swift and Attacker projects. Even the serial was reallocated to a Swift prototype in order to expunge this aircraft from history.

Nothing remained of this aircraft except this proof of concept model and to this day so called “experts" refuse to believe this aircraft ever existed, stating that it is an invention of a deranged what if modeller, however we know different don’t we ?


And a couple of money shots to finish

Well definatly not has good as Brian's, he had a natural flair for bashing two kits together with a minimal amount of filler, something I have not yet quite mastered. However I'm still happy how this one has turned out, except maybe the canopy. In retrospect I think it should have been lower and more streamlined.

I'll let you decide, as always all comments and criticisms greatfully accepted

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