About this Plan

Excalibur. Radio control model, for .10 power.

Quote: "From Camelot to suburban swingers, very little remains unscathed as Will Dawson proves the pen is sharper than even a legendary sword.

A large sheet of drafting paper was taped down to the kitchen floor, and pieces of various aircraft were glued in place. The piece that represented the airfoil was taken from the center-section of a Midwest foam wing. The piece that represented the planform of the wing was taken from a built-up version of the Midwest unit supplied by Owen Kampen. The piece of tail was stolen from G&K's 'Cobia' design. The other pieces were fitted in between according to Chuck Cunningham's 'R/C Design Made Easy' Formula. So, all you guys, I owe you.

The Excalibur was designed to this particular size to utilize the new Micro-Avionics XL-IC and Orbit Electronics 9.4 ounce systems, and the radio compartment was drawn around Dick Rehling's new two-plus-two servo mount for these systems. The Max .10 was used because it's the best RC engine in the smaller size category, both from a power and a throttle standpoint. Since the Micro and Orbit rigs were not yet available when this 'design' was pasted up on the kitchen floor, I drew in the small Kraft servos. All of the first prototype flights were made with a Kraft Gold Medal rig. When the Micro-Avionics system became available, it was flown in the Excalibur.

Now for the flying. It takes off from any facsimile of level ground and goes where you point it. There is no gyroscope in the cockpit and it won't free flight. It's just another multi, Clyde, only smaller. It costs less to build, uses less of that $4.00-per-board-foot material known as balsa, and it can be finished in a few evenings. You can leave the wing in place, throw it in the trunk of your new Riviera..."

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.
