About this Plan

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..."

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
