Plan file details

Top 20 - Lively aerobatic model. Wingspan 42in, for 4 function radio. Quote:- "Top Twenty was designed at the outset as a club-20 aerobatic model, which caused a lot of head scratching as to wing areas and weights - and of course motors. In this case, I based the design on the capabilities of the Veco 19... the all-up weight I had to aim at had to be under 3lb, giving the model a wing area of 300 sq in or theareabouts for a reasonable loading. To achieve a good smooth performance, a medium to long moment arm was used, with a 20% tailplane area..." Top 20, Radio Modeller, December 1977. Direct submission to Outerzone.
