HI, I SAW ONE OF THESE BACK IN THE 60s AT REDHHILL AIRFIELD UK IN A HANGE.R REGISTRATION I-DONP IT WAS A FUNNY LOOKING AIRCRAFT.

One of these interesting machines G-BCRH was imported into UK in early 1970s via Lydd airfield in Kent. The pilot reported that take off needed care as the temptation to over rotate might stuff the tail booms into the tarmac.
The promising performance on so little power is a tribute to minimalism...which is also evident in the restricted cockpit capacity.

According to the entry in 'The Illustrated Encyclopedia of Aircraft' the Alparma 75 is a re-engined 65 using a 75-hp(56kW)Praga D flat four piston engine. Maximum level speed 135 mph(217km/h)cruising speed 119 mph(192km/h). The aicraft was also made in Argentina under the name of Mantelli, the AM-10 was powered by a 65-hp Continental A65 engine and the AM-11 Albatross by a 22-hp Ambrosini P-25 engine!

I am last pilot to flyng a AM 10 in 198O
