About this Plan

Pheon 100 - Radio control glider. 100inch Standard class sailplane.

Quote: "This successful 100S class glider (100 inch span for two function radio) was designed by John Digby.

Pheon 100 was designed during a Christmas holiday some three years ago. I was making slow progress on a 144 in open sailplane and had no flyable models at the time. What was needed was a quick to build smallish ballastable model which would give me some slope and flat field flying during the blustery Winter months. It was intended to finish the open class model in time for the Spring but as it hap-pened the new model kept me flying all year, started to draw up a rough plan with the following points in mind.

1. Smallish model (approx 100 in) ballastable to allow use in higher winds.
2. Wing section to be the very fashionable Eppler 205. I had been looking for an excuse to use this section since it came to the forefront after the '81 F3B World Champs.
3. I wanted to try epoxy/glass skinning of the wings which was also becoming very popular.

Construction was to be kept as simple as possible as I wanted to get airborne, most of the building materials were pinched from the open class model which did not get completed until a year later.

Construction. Construction is very simple and straight forward. Therefore I will not give a stick A to B type description but highlight some of the methods I have used. The fuselage is a simple box build from 1/32 in ply with 1/8 sq spruce longerons. I find it easiest to trace the position of servo rails, wing tube holes, tailplane bearing position, etc, onto the inside of both fuselage halves and then stick the two halves back to back with double sided tape prior to drilling wing tube and tailplane mounting positions.

The fin assembly is best built up on one half of the fuselage. The fuselage sides are then joined at the wing tubes before pulling together at the front and rear, ensuring all is square. Don't forget the 1/8 in ply block for tow hook attachment. Closed loop was used for rudder and bowden cable for elevator linkages on the original. I would recommend one of the following for fuselage covering..."

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.
