About this Plan

Twizzler. Jetex contest model.

Quote: "The Twizzler is an out-an-out contest model. Designed by Dick Twomey it is a 28in competition model designed for the Jetex 200. It is claimed to have a vertical climb - I bet it went up like an express lift (elevator for those in the Americas). It's a shame we don't still have these motors around, maybe the Rapier's will return!"

This is a modern redrawn plan in PDFvector format.

Quote: "Convinced that the high thrust-line layout is the best for Jetex duration, Dick Twomey has developed the 'Twizzler' (a name born recently in the excited broadcast commentary of the Supermarine Attacker upward roll at the Daily Express Air Show) from his renowned Firecrest (oz5369) design. He has found a simple way of doubling the power, while halving the engine run, which is perfect for open ratio competitions. The climb of the Twizzler is thus stepped up to over a 60° angle and recently it established the best ratio in a power contest..."

Please find attached photos [main pic, 003, 004] of the Twizzler I constructed several years ago, still unflown. Regards,

* 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.
