About this Plan

Ringer - Free flight 1/2A power model. Design by BA (Red) Thompson.

Quote: - "USAF's perennial team member has used this 1/2A and a contest winner to help pile up team's winning points at the 1964 and 1965 National Champs...
The Ringer is our answer to the statement: There's a contest Saturday, what can I build and trim out in five days?
We built two in three days after work and were in bed by midnight, too. The Ringer's construction is straight forward and may look weak (the wing and tail) but a few well placed braces and gussets plus a good covering job give you 450 sq in of lifting surface that are as free of flex as any construction (short of geodetic) we have tried. It is a large plane for 1/2A but having flown eight years in Texas, we found that square inches equal seconds when there is no lift, and will keep you in sight when the thermals are strong. Another thing that may sound odd is the addition of nose weight but under the new short engine run rules, we determined that more total time would be obtained by achieving good transition at engine cut off than the 1/2 ounce of weight we were carrying would lose us, hence the short nose moment."

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.
