Burn in the same arson attack that destroyed the Opticas.

Two photographs are in the 1971 december issue of Popular Science Magazine. Shows breakdown of major parts.

Land Development Aircraft
Role Experimental utility transport
Manufacturer Lockspeiser
Designed by David Lockspeiser
First flight 24 August 1971
Status Destroyed, cancelled from register.
Number built 1
The Lockspeiser LDA-01 (Land Development Aircraft) was a British seven-tenths scale research and development aircraft, which was designed and built by David Lockspeiser to prove a concept for a low-cost utility transport.

The LDA-01 was a single-seat canard monoplane, fabric covered with metal construction. It had a canard foreplane which was the same size as each mainplane. The wing was mounted at the rear-end of the box structure fuselage which was fitted with a four wheeled landing gear. It was designed to be fitted with a detachable payload container to allow easy conversion between roles, and was powered by a rear-mounted pusher engine. The LDA-01 G-AVOR first flew on 24 August 1971 at Wisley in Surrey, under the power of a 85 hp (63 kW) Continental C85 piston engine, but was later refitted with a more powerful Lycoming O-320 engine. The aircraft (which by this time had been re-registered G-UTIL) was cancelled from the aircraft register as destroyed in 1987.[1] [2]

Want to build a 1 /4 scale RC model, where can I get more specs please?


Do you have any comments?
