About this Plan

Aeronca Champion. Scale model for RC. 141 in span, 2806 sq in area, for 40-50cc power and 4 channel RC. Model # pl-1105. Scale is 1/3. Featured in RCM 11-91.

Quote: "The most difficult part of this presentation is that John Marquette was not able to write the construction article before he became too ill to do so. Clearly, it is a project which will appeal to the well experienced modeler only, at least in its present form.

The design is not that of a typical scale model. The whole concept is one of replication. It is also clear that most modelers contemplating taking on the task will obtain nearly all of the information they need from the well detailed plans. The original model did not employ spruce in its construction as that material is not generally available in Australia. A Malayan timber called Aluce was used. However, intending builders may certainly use spruce. In reviewing the plans, John said this should not involve any weight penalty. Operation of the model's flying surfaces is by cable, as with the full size aircraft. This factor applies throughout most of the construction.

We always considered the operation of the landing gear on the full size airplane as one of its finest features. It was way ahead of its time in landing gear design. John Marquette was keen to duplicate this in miniature and the plans show a good illustration of the parts which need to be made.

John always felt that kit manufactureres marketing versions of the Aeronca 7-AC had failed to get the windsceen right. This arplane uses a blown 'bubble' windscreen and a large oven or other substantial means will be neededfor this task. Once a male mould is made, a local blow molding company shoulld have no trouble in producing a copy of it..."

Notes

* 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.

Scaling

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.
