About this Plan

Force 5 - Radio control sailplane. Standard Class Sailplane. Wing area 839 sq in.

Quote: - "Force 5. Frail birds and high winds don't mix too well. Here's a machine for those less than perfect days . Howie Applegate... Force 5, described by the "Beaufort Scale" as a fresh breeze of 19-24 miles per hour, or 16-20 knots. Although some of us sailplaners don't feel too comfortable flying in Force 5 winds, this ship is designed to take it, and handle well to boot.
This aircraft is designed around a wing with an aspect ratio of 11.19, which is quite normal for machines of this size. The airfoil is a Goettengen 609 which is blended at the tips. The wing outer panels are washed out approximately 2-1/4 degrees, which gives very desirable stall characteristics. Let's get on to building..."

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.
