About this Plan
The Challenger. Free flight Clipper Cargo contest model, for .020 power. All-sheet design.
Quote: "Now that the rules have changed for the Clipper Cargo event it won't be necessary to have a truck to transport your model to or from a contest: And most workshops will once again be large enough to build and store one.
The span limitation of 48in coupled with the .020 engine is a realistic limit. But perhaps the most important change in the Clipper Cargo rules is that of being able to build a heavier model without being penalized: as the rules now state, the model's performance will be judged on the total weight lifted including the weight of the model.
This means models can be built more rapidly and ruggedly, through the use of more balsa and simplified construction - features lacking before. Streamlining will undoubtedly come into vogue since added weight can be used to advantage.
The 'Challenger' was designer with all this in mind, plus some of the elements associated with every competition - spectators, other contestants, parked cars, to name a few. The all-balsa structure featuring a partly solid fuselage provides a solid mount for good engine operation, the solid wing and tail assembly can be patched on the field and flown before the cement dries.
Anyone who has built a hand-launched glider will have no trouble with this type of construction. Flying the model is easy. Landing gear and wing can be shifted until best take-off and flight characteristics are obtained..."

* 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.
