1931 Heath LNB-4 Parasol UM

From: $49.00

Credited as the father of the modern home built movement. Ed Heath’s LNB-4 Parasol was one of the only factory supplied kits in the early 30’s that an aviation enthusiast could build at home and receive certification by the FAA. Plans for the original Heath Parasol were published in the “Flying and Glider” manual and in Modern Mechanix magazine. Heath sold on order of 1000 kits with several hundred completed during the great depression. The LNB-4 features a parasol wing and generous empennage making it a logical choice to model for RC flight. Builders of our laser cut model of the 1931 Heath LNB-4 Parasol UM will be rewarded with a stable model featuring classic 1930’s lines.
