About this Plan

Qualifier II. Radio control sport aerobatic plane.

Quote: "Someone on the RCGroups online magazine was asking about availability of these just silly-rare plans, so I looked around my shop and found them. Can't remember where I got them from.

I've always liked the first design Qualifier by Gerry Nelson, and found the biggest change was the tricycle gear on the II version, although I have an allergy to nosewheels - model or full-size. These came from the publication Model Aircraft World by World Engines, volume 1, no. 2 dated March, 1963. Don't have any other months of this magazine/newsletter, but I know it was integrated into the Grid Leaks magazine in the mid-Sixties and when ACE R/C stopped publishing that, it came to be part of the American Modeler magazine, as a column.

This airplane is intended for a full-house 10-channel reed system (RETMA, deciphered as Rudder, Elevator, Trim [for the elevator control], Motor and Aileron - remember, reed systems used one channel for each direction of each control), but will fly well on a modern proportional system. Rather than selecting only the drawings and article, I scanned the magazine in its entirety. Too difficult to separate them and lets you see, in a small way, how things were in the day. I like the front-page article on wiring a reed system. I wonder how many would put up with that mess today?

This is where what you are doing really shines - the newsprint paper is so old it not only yellowed, it's falling apart. Very risky, running this paper through the scanner at the print shop. Other than you, or maybe the AMA, no one would care how losing this airplane design would matter to anyone. But, similar to losing only one tile in a floor made up of thousands, this drawing rounds out, a little more, the history of model aviation and those who helped in making it what it is today..."

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.
