The Gordon Bennett Trophy could have been running through the 1920s and '30s, with rules paralleling the Schneider Trophy rules - but for landplanes. Italy should certainly have participated, and let Mario Castoldi base the landplane racers on his Schneider Trophy designs. For 1926, the Italian Gordon Bennett Trophy entry would have been Macchi M.39T.

Macchi M.39T (T for Terra) was a single-seat landplane of mixed metal and wooden construction. The wooden wings were wire-braced, with two thirds of the upper surfaces used as low drag surface radiators. The pilot sat in an open cockpit parallel with the trailing edge of the wing. The cockpit's windscreen and "turtledeck" were somewhat raised for better visibility, compared with the seaplane version. Being lower weight than the seaplane, the M.39T was given a shorter wing span.

Macchi built two types of M.39T: two trainer aircraft and three racers. The trainer version had a 447-kilowatt (600-horsepower) Fiat AS.2 liquid-cooled V12 engine, while the racing version had a 597-kilowatt (800-horsepower) Fiat A.S.2.

On 17 October 1926, the three M.39T racers took part in the 1926 Gordon Bennett Trophy contest at RAE Farnborough, Hampshire, England. Major de Bernardi, took first place with an average speed of 426.7 kilometres per hour (265.1 mph), setting a new world speed record. Three days later, on 20 October 1926, de Bernardi achieved a new world speed record of 442.6 kilometres per hour (275.0 mph) over a 3 kilometres (1.9 mi) course at Farnborough.

Thanks for reminding us this rare M39, cousin of the even-less famous push-pull cinque-motore M39/5m:

... But how much wing and how many floats does it need to carry the weight of the five engines? Not to speak about surface area for the radiators...  ;D

M.39T...
You can have it in any color - as long as it is red.

Tophe:
Beautiful in colour, thanks!
