About this Plan

Double Jabberwock. Enlarged radio control (and electric powered) version of the classic rubber model.

Quote: "Noted designer Don Srull has another winner in this 15 powered electric classic. A double size model of Wally Simmers award winning Jabberwock of the late 1930s.

The original Jabberwock was one of the best flying rubber powered free flight contest models of the late 1930s through the 1950s. It was designed by Wally Simmers, an outstanding modeler and competitor of that period.

The Jabberwock and another famous design of Wally's, the Gollywock, were kitted by Midwest Model Supply Company for quite a few years, and many of today's modelers (as I did) had their first real modeling success with these simple, great flying airplanes. Both of the designs are now regarded as classics, and can still occasionally be seen flying at fields that are large enough to contain super performing free flights.

Not being one of the fortunate minority with access to a good free flight field, but still longing to enjoy these old timers, R/C seems to be the answer. The quite, smooth power of the modern electric motor systems, especially when geared down and using large diameter folding propellers, is a natural choice for power. So here is the Jabberwock, doubled in size to carry an Astro 15 motor, a 12 cell battery, and three channels of mini radio gear.

It is a fine performer, easy to build and easy to fly. It will deliver an honest 10 to 15 minutes in dead air; and since the Jabberwock has an excellent glide, any kind of thermal activity will keep this bird up as long as your neck and radio batteries hold out.

Because of its silent powerplant, and its light wing loading (about 16 ounces per square foot), the Jabberwock can be flown from almost any schoolyard, athletic field, or large parking lot.

With minor changes, the model can also be powered with a .20 to .25 cubic inch glow engine. A change in the firewall..."

Here are some pictures of my Double Jabberwock, a Don Srull design I downloaded from Outerzone [more pics 005-009]. The plane is equipped with a Hobby People 2814/06, A .15 glow equivalent. 11/5.5 APC prop with an ElectriFly 25 amp Silver Series ESC. Flying weight with a three cell, 2200 mah pack is 46 ounces. This produces an 8 1/2 ounce/sq. ft. wing loading. Performance is outstanding with glides that seem to last forever. Excellent thermally abilities. LED lights installed internally for night flying. Covered with Top Flight transparent yellow Monokote. Visibility is amazing. Working on The Yogi now. Another Don Srull design.

* 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.


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.
