About this Plan

Beatnik. 56in span open class Power FF from Model Aircraft, June 1960. For engines up to 3.5cc size.

Quote: "Beatnik. Open class power model by Jim Baguley.

Jim Baguley's series of articles on power model design, which appeared In Model Aircraft between December 1959 and March 1960, aroused considerable interest both here and overseas. In view of this fact, we have great pleasure in presenting here the plans of Jim's latest power model.

THIS is the sixth development in a particular series, the main improve-ments over earlier versions being structural, and an increase of tailplane chord. The most potent 3.5 cc engine will not prove too powerful for it and the ideal is probably a 19 glowplug motor, by using which the flying weight can be taken down to 14 oz. The original Beatnik weighed 16-1/2 oz with a modified Oliver, and using over-hard balsa all round. The only hard balsa needed is that used for the fuselage longerons.

The construction is very simple enabling building time to be a nominal 20 hours, and while the plan contains ample information for an average person to complete Beatnik, the following general constructional notes will prove of interest.

Fuselage. This component is as slim and simple as practicable, the completely enclosed 10 cc tank being sufficient for any motor up to 3.5 cc. To gain the full advantage from this form of construction the longerons should be made from hard balsa and the sides from soft. The section is sanded and carved to a semi-circular shape at top and bottom as shown.

Wings. The tip shape is a concession to appearance but the construction is essentially practical. Care should always be taken with this type of wing tip to leave no gaps between the parts during assembly, or cement shrinkage may produce excessive warps. A natural and desirable tendency is towards wash-out..."

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.
