AMP 1/48 Supermarine S.5 Schneider Racer

In 1911, a time when floatplanes and flying boats were barely capable of leaving the water, Jacques Schneider introduced the at a banquet following the 4th annual James Gordon Bennet race for landplanes, for a similar race with seaplanes. One of the rules was that the winning country had to organize the next race. The official name of the prize was “Coupe d’Aviation Maritime Jacques Schneider”. If an aero club won three races in five years they would retain the cup and the winning pilot would receive 75,000 francs. The races were supervised by the F.A.I. (Fédération Aeronautique International) and the Aero Club in the hosting country. Each club could enter up to three competitors with an equal number of alternates. Schneider, the son of a wealthy arms manufacturer, had a vision that the seaplane was the best and fastest way to span the oceans. Without the need of airfields and runways would be the direction of the future. It did result in the development of a new generation of very powerful aircraft engines, which would ultimately guarantee the superiority of landplanes. However, the ultimate Schneider Cup racer, the Macchi-Castoldi MC-72, set a world speed record for seaplanes that is still unbeaten today, although it never participated in any Schneider Cup contest.

Designed specifically for the Schneider Trophy competition, the was the second in a line of racing aircraft that ultimately led to the Spitfire.

After the setback of the 1925 Schneider Trophy at Baltimore, when the Supermarine S.4 monoplane had crashed during a test flight as it rounded the first marker, and the lack of time to design a new machine for the 1926 competition, Britain had to wait until 1927 for its next entry. Reginald Mitchell abandoned the all-wood structure of the S.4 in favor of composite construction with the semi-monocoque fuselage built mainly of duraluminum including the engine cowlings. The aircraft had a low, braced wing with spruce spars, spruce-ply ribs and a plywood skin. The wing surface radiators were made up of corrugated copper sheets that replaced the Lamblin type radiators of the S.4. Although it was felt that the Napier engine had been developed as far as possible, and that a Rolls-Royce engine might produce higher speed, Mitchell decided to keep with the Napier Lion VII for one more year. The engine was closely cowled. Space in the fuselage was so limited that part of the fuel was carried in the starboard float, where it helped to counteract the huge torque of the propeller on take-off. For the same reason the starboard float was offset eight inches further from the fuselage centerline than the port float. Everything in the S.5 was designed to reduce drag, with a frontal area as small as possible and rivet heads finished flush with the surface. The cockpit of the S.5 was so tight that only a pilot shorter than 5' 6" would fit inside and he had to drop in sideways through the opening before turning into a sitting position.Three aircraft were built, one with a direct drive 900 hp Napier Lion VIIA engine, and the other two with a geared 875 hp Napier Lion VIIB engine. The first S.5, N219, first flew on June 7, 1927.

Sir Hugh Trenchard was fully aware that the British defeat in the 1925 Schneider Trophy was mainly due to the technical superiority of the other competitors, but also that the lack of team organization played a part. Consequently, in May 1927, when the Air Ministry decided that it would finance and organize the 1927 British entry, an RAF High Speed Flight was formed to operate and fly the aircraft in the race.

In early July, Flight Lieutenant S.N. Webster flew the S.5 for the first time and after flying at over 275mph, he recorded in his diary, "Very nice. No snags." Once it was airborne the aircraft performed well but it was not easy to get it off of the water. This was partly due to a dipping port float, caused by the propeller torque, forcing the plane to turn left and spray from the bow wave that made it almost impossible for the pilot to see.

The 1927 Schneider Trophy took place at Venice and the 50km triangular course, which had to be lapped seven times, covered the length of the Lido in front of the Excelsior Hotel, with a sharp turn at each end. The race was scheduled for Sunday, September 25, but was postponed to the following day after strong winds and a swell made racing impossible. Only two countries had entered: the defending Italians in Macchi M.52s piloted by di Bernardi, Guazetti and Ferrarin, and the British with two S.5s, N219 and N220, piloted by Flt Lts Worsley and Webster respectively, and a Gloster IVB flown by Flt Lt Kinkead.

Kinkead had drawn the right to go first and recorded an opening lap of 266.5mph in his Gloster. However di Bernardi, who followed him, reached a speed of 275mph and the British officials, watching from the roof of the Excelsior Hotel, realised that only the S.5s would have a chance of beating the Italian's high first-lap speed.

Webster in N220 was next away, followed by Guazetti, then Worsley in N219. All Italian eyes were fixed on the scarlet Macchis when it began to rain. Almost at once disaster struck the Italians. Ferrarin's plane came down in a cloud of smoke as he dived toward the shore. Soon afterwards, Bernardi was forced to retire with engine trouble, leaving the three British pilots racing the one remaining Italian, Guazetti.

After the fifth lap, Kinkead was forced to retire with engine trouble after a loose strip of metal had wrapped round the propeller blade. This just left the two S.5s flying against the Italian, who soon came to grief when one of his fuel tanks was punctured and he came down on the lagoon, narrowly missing the Excelsior Hotel.

The British pilots carried a simple but effective device for recording each lap as they completed it. It consisted of a small board with holes cut in it which were covered with paper, one of which was punched out after each lap. Flt Lt Webster thought he might have made a mistake with his hole punching and ended up doing an eighth lap. His S.5 had won the race and his average speed of 281.66mph set up a new world speed record.

After the Schneider Trophy victory, the RAF pilots became public heroes, but outside of Southampton there was little mention of Mitchell. His total lack of vanity and self-importance led some people to believe that the S.5 was the result of a lucky chance. Only the members of his team knew of the months of concentrated effort and dedicated work that had been needed to design the fastest airplane in the world.

S.5 N221 crashed during an attempt on the world air speed record on March 12, 1928, killing Flight Lieutenant Samuel Kinkead, who had flown the Gloster IV in the 1927 Schneider Trophy Race.

Because of the ever increasing time and costs to develop and build the special racing planes, it was decided that the Schneider Cup race would be held every other year, instead of every year. With the UK as a host, the next race was held in 1929 near Calshot naval air base on the south coast.

With the S.5, Mitchell decided that the Napier engine had reached its limits of performance. He redesigned the S.5 for the 1929 Schneider Trophy race as the S.6, using a new Rolls-Royce engine. Concern over the unreliability of the Gloster VI led to the RAF’s High Speed Flight entering the S.5 N219 with the direct drive 900 hp Napier Lion VIIA engine, along with the two S.6s. Flown by Flight Lieutenant D'Arcy Greig, N219 finished third at a speed of 282.11 mph, behind the winning S.6 flown by Flying Officer H.R. Waghorn and a Macchi M.52.

The kit

To my knowledge, this is the first 1/48 injection plastic model of the Supermarine S.5. Previously, only the S.6B was available in plastic in this scale, in a kit that was originally released by Hawk Models in the 1950s and released over the years since by Testors, who bought Hawk some 60 years ago.

has become well-known as a producer of kits of 1930s aircraft that previously had not seen the light of day. This kit is unlike the others, in that it is a fairly primitive limited-run kit. Think MPM 20 years ago and you’ll have a good idea what you are working with.

The kit provides decals for N220 at the Schneider cup race and during the world air speed record in 1928.


I had high hopes with this kit, but once the box was open shortly after arrival from Ukraine, I realized I was going to be taking a time trip back to Modeling Hell and the early days of limited-run kits. I wasn’t wrong. I’ve always liked the lines of the S.5 the best of Mitchell’s racers, and was determined to have this in the collection, so Perseverance was the name of the game here.

I quickly determined there was no need to worry about putting the engine in, since it was too big to fit inside the cowling and wouldn’t be seen. Should you want to destroy the beautiful lines of the airplane by taking off the cowl to display the engine, you should expect to do a LOT of work to bring that to an acceptable look.

There’s lots of flash that needs to be carefully cleaned up so that you don’t take any of the part with the flash. There are no attachment points for the floats and their struts, though the instructions to tell you where to measure to on the floats, which I did. The cockpit is extremely basic, as it was on the real thing, so I only worried about the “seat” and some safety harness, since nothing else would be seen with the windscreen in the down position.

With careful assembly, I only needed a bit of CA glue along the seams, and then to rescribe the detail. I did not attach the floats until the model was painted and decaled.


With a model this small, the painting isn’t easy. I painted the blue areas, using Tamiya X-4 Gloss Blue, with some Tamiya X-14 Sky Blue mixed in to get the proper shade. I then carefully masked off all the blue areas with Tamiya tape, then applied Tamiya Gloss Black, followed by Vallejo White Aluminum to stand in for Aluminum Dope.

The decals went down under Micro-Sol, though I had to slice the national insignia on the fuselage to make it settle over the radiator system.

Once the model was painted and decaled and a coat of Clear Gloss was applied, I attached the floats, using CA glue. The model felt very flimsy at this point. I used .003 stainless steel wire for the bracing, attached with CA glue. Once the bracing set up, the model finally became rigid.


Not a model to examine closely, but from a distance of a foot, it looks very nice. One can easily see the beginnings of what would become the Spitfire in this airplane. It fills a gaping hole in the collection of any serious Spitfire Boffin.

Recommended for those with Perseverance and Determination, who have experience with the earlier and more primitive and difficult limited run kits. A lot of modeling skill applied to the project will result in a nice-looking model of an important airplane. I’d like to see AMP do the other famous Schneider racers in 1/48.

  1. Thanks for sharing this background, Tom.
    Your build, although not an easy one, clarifies the history.

  2. That's a nice S.5 Tom!
    Perseverence won!

  3. Nicely done - interesting bird!

  4. Nice build, as usual, Tom. What an elegant machine the S.5. Thanks for struggling through this one to treat us!

  5. The article is seconded to none ...informative, entertaining, and makes the reader want to finish the article. Just a well balance piece with the writing, modeling and photography. It doesn't get any better.

    Thank You for sharing TC.

  6. Must have taken some guts to mount this monster of an aeroplane and fly it to the absolute max of its capabilities.

    So it was a OOB build...was prepared for a description of a total rebuild of Eduard's latest Spit. Nice model and story as always, Tom.

  7. Looks great but doesn’t sound like fun, Tom. Thanks for the warning! I guess I’ll stick with my 1948 Hawk S.6...😂

  8. Great work and narrative.

  9. Good history as usual Tom and great period photos. Looks like you backed off the camera a foot so your S.5 does indeed look fine to me. Nothing like a kit from hell to put things into modeling perspective. Doesn’t look a fun plane to fly either. Glad you tackled this one successfully.

  10. Nice work on this dog Tom.

  11. This is an awesome build, Tom (@tcinla). I have build a couple of the Amp helos, but I had no idea they had a model of this racer. I am in the midst of a Special Hobby 1/48 Martin Maryland, so I feel your pain with this build. Your S.5 shows that even challenging kits can look great with a little TLC.
