About this Plan

Big Boy IV. FAI competition power model. World champion design.

Quote: "The origin of the Big Boy FAI series reaches as far back as 1960, when the FAI announced an engine run reduction from 15 to 10 seconds. Till then I had stuck to small models of conventional layout, using mainly 09 diesels ...designed for .15 power, using the then new Austrian Bugl 15 Oliver diesel, with the highly efficient Czech 8-1/4 x 3-1/2in MVVS wooden props. An ED timer for sutoff, plus a Tatone DT were used. Neither autorudder nor autostab were employed. The initial experience with Big Boy I was quite good, and prompted me to conceive Big Boy II..."

Notes

* 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.

Scaling

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.
