Intro. Radio control model. A 38in span model for Club 20 racing or sports flying, using 2-3 function radio and .19 - .20 engines.
Three designs in one feature. This RCME article covers the "Intro", "Hot 20" and the "Mustang" (aka Mustard) three variants of the same basic design.
Quote: "If simplicity is what you are looking for in a Club 20 racer, then the Intro is for you. Actually, simplicity and serviceability are the prime requirements of pylon-racing - just ask any of the top notch FAI race men and they will confirm.
DESIGNED primarily for the Club 20 Pylon racing class (also for Quarter Midget with engine control), the 'Hot 20' and 'Intro' are also very useful sports acrobatic models capable of exciting manoeuvres. Should the model be constructed with acrobatic flying as the main purpose, a clunk tank may be fitted. A metal tank will give only a limited amount of inverted flying, which is intentional and is to allow the engine to be stopped at the completion of the race. A good .19 or .20 capacity R/C engine should be adequate power for all forms of flying and, for sports flying, a .15 engine is adequate.
Whether you fly the models as pylon racing aircraft or sports models you should find them fast, responsive and enjoyable. The 'Intro' is the easier to build of the two models and is a little squarer in looks. It is not however, noticeably slower in racing and should prove to be highly competitive. Two versions of the 'Hot 20' are shown, one in the guise of a semi-scale Mustang referred to locally as the 'Mustard' for fairly obvious reasons. Detailed instructions cover the building of the 'Hot 20' and I have added a few notes at the end regarding the differences in building the 'Intro'. The 'Intro' should be suitable for anyone who has built two or three models previously.
Before commencing construction, familiarise yourself with the plan and instructions. Sketch on the plan the proposed position of your radio equipment, the models are more likely to finish nose heavy than tail heavy, and the radio installation should be kept rearwards. With modern miniature radio equipment there should be no installation difficulties... "

* 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.
