About this Plan

Fli-Hi. Simple HLG from Vern Clements.

Quote: "This is an unusual hand-launch glider. It was developed with the idea that beauty as well as high performance can be incorporated in this type of model. The graceful pod and boom fuselage adapts itself to a powerful launching technique. The pod boasts a wide cross-section and a celluloid canopy which suggests realism and adds streamlining. The extra pod laminations are practical since they add weight in front of the balance point which aids in obtaining the proper center of gravity (a lead weight must also be countersunk in the nose).

Each test model of this design incorporated a longer tail moment arm than the previous one. The 80% tail moment arm version presented here reaches an astonishing altitude when compared to its shorter coupled brothers. The long moment arm increased the looping radius over shorter designs, which results in a recovery at sufficient altitude to locate thermals. This factor was very apparent in a Boise (out in Idaho), hand-launch glider competition where the Fly-Hi took first place with ease.

Test glide from shoulder height until a flat glide is obtained, adjusting the rudder for turn. Don't use full power on the first throw..."

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.
