Compact Disc (oz12307)
About this Plan
Compact Disc. Radio control sport model, for 1.5 cc diesel engines.
Quote: "Do you believe in unidentified flying objects? Pat Mardell offers concrete evidence - of the 1.5 cc kind!
After almost two decades of building and flying exclusively vintage models only, I decided it was time to build a model of greater agility and speed, to test my flying ability, thinking that my reactions must have diminished over the years without any severe demands being made on them. As it was to be a model simply to satisfy my curiosity, it would need to be quick to build and inexpensive; in addition to this it would have to be compact. The result was the 'Compact Disc', a simple design, economical to build, and fun to fly (on low rates) and hair raising on normal rates!
Construction: Basic wing frame, stage 1: Construction is simple, but must be carried out in the following order. First mark out a twenty inch circle on your building surface. Mark out spar and rib positions using dimensions given on the half-size layout. Cut out required number of segments and closure segments.
Pin down the first layer of segments finishing with the closure segment (this may require trimming). Next, add the second layer of segments, but this time turn them over so that the joints are diagonal to each other (transposed) for strength. Add the spars after slotting (half joint) for ribs. Now the 1/4in x 1/8iu ribs are slotted to lit over the spars and the 1/4 x 1/8 E pieces added to complete elevons. This completes the basic wing frame stage 1.
Wing frame, stage 2. The frame remains on the board. Add 1/4 x 1/8 medium balsa (horizontal) to hinge line 3 and 4 of elevons, stretching from the outmost point to the centre rib positions. Add 1/8 x 1/8 med balsa to elevon ribs, centre rib and 1/4 x 1/8 horizontal to piece E inboard rib of elevon..."

* 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.
