About this Plan

Pen Friend. Radio control sports racer.

Quote: "Build This Sprightly Sportster For .20 Engines and Lightweight Receivers. Successor to 'Blister', A Pylon Racer in Miniature. Pen Friend, by PE Norman.

This model, which has been designed and built to have simple but attractive lines, should appeal to those modellers who require a small fairly straight-forward model to build and fly. It is in effect a small edition of my Blister (oz4912) but with a very much simplified construction, and is powered by a Cox 0.20 engine.

Two types of wing construction are described, one the straightforward type which has the usual ribs, mainspar, leading edge, trailing edge construction and tissue or silk covering. the other extremely simple to make and consists of a slab of expanded polystyrene, sanded to section and suitably reinforced where necessary with balsa wood. The Rx employed on the original is In Otarion working a Citizenship actuator. the whole battery requirements being 3 volts supplied by two U7 batteries.

Total flying weight of the model is 11 oz using area about 140 sq in. These small models are very sensitive to rudder, so only a slight amount (about 3/16 in, either way) is ample when first testing. This may easily be adjusted by the simple method of decreasing or increasing the angle of the actuator rod, which fits in the slot in the leading edge of the rudder itself.

Radio space should permit the use of MacGregor Minimac RCS Guidance System or any of the other subminiature receivers now available, which do not require extra actuator batteries.

Fuselage. Commence by cutting out the fuselage sides from 1/16 in balsa sheet, and reinforce with another piece of 1/16 in sheet back as far as F3..."

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.
