About this Plan

Hornet 3. Class A combat model.

Quote: "MOST PEOPLE, after flying a swept wing model have their reservations as to making a change from the basic wing design which has reigned so long in this country, due mainly through lack of development. Such development requires a group of people working together, such as in the Northwood days when the APS Razor Blade (oz2455) came to the fore. It takes a long time for an individual to develop a model up to competition standards from scratch. So at this stage we must thank Mick Tiernan and his brother Dave for starting it all off. Having all been chased round the sky in 1972 by Mick we got the message, then with the combined effort and enthusiasm of the Glevurn (Gloucester) team (Mick Lewis, Derek Dowdeswell, Dave Cox, Tim Court and yours truly), the 1973 swept wing designs were developed very quickly over the winter, everyone trying out their own different ideas.

First impression of a swept wing model is that it feels light on the lines and the 'know where it is' feel has gone. But the most important feature to look for is that its turning ability is different. I say this because in some cases the Ironmonger (oz5602) and Warlord (oz12240) can be equally as tight in the first 'loop' or 'bunt', but the recovery of speed is slower than this design which will do consecutive 'loops' or 'bunts' without the inotor being overworked and losing height. (Keep the motor happy!) A consistent engine, especially a Copeman Mk. IV Oliver, will solve most of your problems.

The other features that attribute to its manoeuvrability is in its shape. Area has been transferred to the centre of the model where it is more effective and this together with a narrow tip chord allows use of full control without loss of speed. This wing shape is more flexible than the normal wing, where cracks frequently occur in the trailing edge curve close to the elevator... "

Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

* 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.
