About this Plan

Filibuster. Ted Buxton's 30 inch lightweight rubber model. From Aeromodeller March/April 1947.

Quote: "THIS tough model airplane, suitable contest flying in any weather, is the most recent development of a line of similar jobs. Its ancestors flew in competitions on days when trees trembled like jellies with St. Vitus' dance.

Starting in 1943, Model No.1 passed away early in its 'life,' for 6 minutes, to win the rubber-driven class of the Croydon Club Gala Day. A few weeks later, Model No.2 had an even earlier demise, the first flight it ever made (an out-of-sighter) proving long enough to take second place at the Blackheath Open Day. This model was retrieved, and after some manipulation with the wing areas and the wasting of two contest flights on trimming, its third flight produced sufficient time to finish it fifth on the result sheet of the KMAA Biplane Competition. The next edition worked out third in the 1944 Gamage Cup with an aggregate of 818.0 seconds, the third flight being 409 seconds OOS, while Mark V took fifth place in the 1945 Gamage Cup on a two-flight aggregate of 782.0 seconds, the model being lost on its second flight after 9 minutes.

The development which has taken place over three years has produced a model rugged enough to stand up to the wear and tear of both sport and contest flying. A noticeable feature is the low aspect ratio wing; the large chord making for both increased efficiency and lightness in construction for a given wing area. Naturally the low aspect ratio gives a prop diameter of over half the wing span, but on the basis of wing area everything is normal.

Construction. Fuselage. This is built in the normal manner, 1/16 in gussets being added at wing mount and undercarriage junctions after these items are bound in place.

Wing. Leading and trailing edges are shaped to aerofoil contour after the ribs have been cemented in position. Trimming time can be reduced by packing up the front of the trailing edge section to follow the upper contour of the ribs ; then only the bottom has to be trimmed. Leading and trailing edges are cracked where shown for dihedral..."

* 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.
