About this Plan

F-13. Free flight power competition model.

Quote: "This state of the art FAI power model almost won at the hotly contested Free Flight World Champs last year.

In the 1979 Free Flight World Championships, the F-13 was flown only in the first two rounds and in the fly-off rounds. In the second round, it showed a poor recovery from a stall after a bad transition, so I switched to my backup model, F-12, which had better glide performance and stability. F-12 continued to max as I had expected it to but although it as good enough for three-minute maxes; it was not strong enough to beat the world's top models in a fly-off.

During the intervals between rounds, I adjusted the transition of F-13 by changing the auto-rudder timing. In every fly-off round, it climbed higher than in uny of the other models and showed perfect transition.

The F-13 was completed at the end of August 1979, and took only three Sundays for me to adjust the flight pattern for the upcoming World Championships in October..."

Quote: "Second place, 1979 FF World Championship. Traced for MAN by Ray Borden."

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.
