About this Plan

Dragonfly. Free flight rubber powered biplane model.

Quote: "After considerable neglect biplanes are staging a comeback, especially amongst those who want a change from the serious business of contest flying, for there is a certain satisfaction in the steady, stable flight of a well designed biplane and it makes a pleasant change from the screaming climb of the duration monoplane.

However, this particular design has quite a good duration; the prototype after flying steadily over a period of some four years, during which secondary minor repairs have added to its weight, can still knock up 70 or 80 seconds under decent conditions and what is more important can fly well and steadily in strong winds.

For those who imagine that biplanes are difficult to fly (a section of modellers rapidly becoming fewer, I am pleased to say) let me honestly say that they are no harder to fly than a monoplane and may frequently be definitely less critical in adjustment and therefore actually easier to fly.

Fuselage. It is logical to start with the fuselage so here goes: Lay down the 3/32 in sq hard balsa longerons, cement the sheet spacers at the nose and tail permanently to the outside edges - not between the longerons - and lightly cement temporary spacers across the longerons as shown dotted on the drawings..."

* 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.
