About this Plan

Geef. Free flight power model.

Quote: "Development of the 'Geef' design started in 1955 and has progressed to a point where we feel it will more than hold its own in any company. As evidenced by its First place position in the FAI Gas Event at the Nationals with a record time of 22 min 8 secs. Flown in competition from coast to coast, it has proven itself a consistent winner. Even Junior flyers, building their first large gas model, have been successful in building and adjusting it. On the other hand, experienced builders using a 'hot' .19 engine have easily obtained dead air times in excess of the AMA 5-minute flight limit on a 20 second engine run VTO. The use of a small (33%), thin stabilizer is a departure from earlier designs but has considerably improved the glide. The wing with its higher aspect ratio and more efficient low speed airfoil can better carry the load. Several flat-bottomed wing sections were tried and discarded in favor of the under-cambered section shown here..."

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.
