About this Plan

Jabberwock 125 EP. Radio control sport model for electric power. Wingspan 46-1/2 in, wing area 253 sq in.

The original Wally Simmers designed Jabberwock (oz2978) was a Midwest kit circa 1939. This here is a later version for RC and electric.

Quote: "I have had a blast this summer flying 125% enlarged Midwest / Wally Simmers rubber models converted to electric powered and RC. I started with a Dyna Moe (oz12666) and followed up with the Gollywock (oz12665). These vintage designs trace back to the period after World War 2. This was quite nostalgic for me since I built some of these models in my teens.

Both fly great!

With the Covid restrictions I have spent many hours in the basement building or drawing model airplanes….. more so this year than any time I can remember. I just had to complete the trifecta and create a plan for the Jabberwock. I have been using AutoCAD for over 30 years so this comes easy to me. I have attached the plan that was created.

I used the wing and stab plan form from the Dyna Moe and traced the Jabberwock fuselage. The top sheeting was eliminated on the wing. I also used the same flat bottom airfoil mentioned earlier in this thread.

The length of the Jabberwock fuselage is slightly smaller than both the Dyna Moe and Gollywock. The biggest difference is the inclusion of landing gear.

Construction was straight forward and was actually built in less than a week. The model is covered with Ultracote Fluorescent Transparent Yellow.

It uses an Innovative Designs.com C 2204-32 motor with a GWS 7x3.5 prop. I used a 450 mah , 2S lipo as I have on the other similar models.

I am flying with a Spectrum 4 channel receiver and two Hitec HS 55 servos. The Jabberwock 125 EP comes in at 10.5 ounces ready to fly with a wing loading of 5.98 ounces / sq. ft..

My 6-year-old grandson, Graham actually glued some of the wing ribs in place during construction. He wanted to be there for the first flights. I tried a test glide to check balance and then tossed it into air for the first flight. It flew superbly! The next flights were ROG and Graham got some stick time. I haven’t had a chance to see how well is reacts to thermals but I expect it will be identical to the Dyna Moe and Gollywock.

These are delightful models. I hope some of you will try these in the future and keep the spirit of 1940’s modelling alive."

Update 31/01/2021: Replaced this plan with a corrected copy (dimensioning), thanks to JimZare.


Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

Corrections needed on plan (dimensioning): Wing leading edge should say 1/4 square. Wing spar should say 3/16 x 3/8.

* 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.
