Plan file details

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..."
