About this Plan

Zeitgeist - Radio control glider model. Wing area 440 sq in.

Quote: "Zietgeist was originally designed as a rudder only model using a Minimac receiver and Elmic Conquest escapement, and completed many hours of flying in this mode. After experiments with wings of various areas and configurations, the design as presented here seems optimum. Further flying has been carried out with the Galloping Ghost system, using the Controlaire Ghost actuator and the elevator used is shown in the drawings.

WHAT are you going to call it? they asked. Oh! I don't know, we'll think of something, I replied. So went the conversation whilst the 'brains' were at work over a pint at the local. The discussion arose after the news was broken that the local council had decided to limit the hours of power flying on the club's local flying patch. All were agreed that R/C gliders were the answer to the ever present noise problem, and sketchy notes on a soggy beer-mat were eventually resolved on the building board to result in the the latest masterpiece, namely Zeitgeist, being ready for the air. Then the next problem reared its head; the concensus of opinion had been that the glider should be fairly fast so as to avoid the dreaded downwind fly-away bogey.

Now I suppose a fully fit free night man would not have found much difficulty in towing up the brute in a light breeze, but yours truly being, well, just a little rotund, and fleet-footed tow-launchers at a premium, some difficulty was encountered in attaining enough altitude to do more than circuits and bumps.

Try a catapult, they said. So we did. Ah! that's better! and so it was, for a few flights - until the gremlin's decided to give me a stuck-on rudder half way up on a launch - the reason for which I will rnention later.

When repairs had been effected a few days later, and we had one of those rare summer evenings, flying was resumed. All was well, but our local field does have an avenue of trees slap down the middle. Failing light, and eye-sight, made judgment of distances somewhat difficult and the inevitable trip to the twitter-perches ensued.

Try slope-soaring! was the next suggestion from the sages, so the next suitable week-end, the first of many, many excursions to the 'Hoe' was mounted. Well, you've got enough height now! I was told, as I glumly surveyed the prospects of hauling the model from the bottom of the hill after each flight. Oh well, here goes - Eh? What's this? Look, it's staying up! Well that's roughly how my first taste of slope-soaring went. Of course, landing techniques had to be mastered, but this was for me, for sure!

I discovered that the ample dihedral paid off when it came to making quick turns and whilst flying in turbulent conditions. No doubt some folks will disagree, saying it's not pretty..."

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.
