Speedster (oz2163)

About this Plan

Speedster. A fast flying control line sport stunter for 1.5cc engines.

Quote: "Speedster was born whilst driving home from the Stoneleigh model exhibition this year. At the last moment I was asked to give a few demonstration control-line flights. The only aircraft I had were old Unlimited (oz9684) and a Peacemaker (oz1633). In the event 'Peacemaker' sprung a tank leak and I was left with poor, old 'Unlimited'. Whilst the old chap is tough and fun to fly I noticed the crowd was not impressed. 'What is it?' and 'Is that all there is?' How does it fly?' were typical remarks. What I needed was a rather fast flying stunter which strongly resembled a real aeroplane and would easily fit into the boot of the car.

The PAW149 with Schnuerle type porting was removed from poor old 'Unlimited' and design work started. The nose section, cowling and general fuselage outline have been on the board for some time for a racy R/C model which can perhaps now be 'Speedster 2'. Full-size aircraft with this style of upright engine installation were produced in the 1930s although 'Speedster 1' is a freelance design. A removable undercarriage is used as I often fly over long grass and with an undercarriage fitted tend to damage my aircraft with nose-overs.

Wing construction. Cut out 14 ribs to the template shown on the plan. Make them 'full' to begin with, no notches or cutouts. Pin the ribs together in a block and sand to a smooth shape. Using a small saw, carefully cut out the spars, trailing edge and leading edge..."
