About this Plan

Bell P-39 Airacobra. Wing area 743 sq in, for .60 - .75 2 cycle or .70 - .91 4 cycle engines.

Discontinued kit from Top Flite. This is the Gold Edition kit. Scale is 1/7.

Quote: "Congratulations and thank you for purchasing the Top Flite Gold Edition P-39 Airacobra. We are sure you are eager to build and fly your P-39 Airacobra just as we were eager to build and fly our prototypes.

The nice thing about the Gold Edition P-39 Airacobra is that although it is a highly detailed scale model with all the goodies, such as a realistic looking scale outline, built up tail surfaces, retracts and flaps, it is one of the few military aircraft that had a tricycle gear configuration. Those of you who have not yet mastered airplanes that are tail draggers, will appreciate this model's great ground handling characteristics.

One last note before you continue: we highly recommend you get some pictures or a book about P-39 Airacobras or send for your documentation package as soon as possible. This way you can study the drawings and photos to get a feel for how your P-39 Airacobra should look when you're done. This will also help you figure out what scale details to add and decide on a trim scheme.

Well, this should be enough to get your juices flowing, so get your other projects off your workbench, say goodbye to your significant other for a while and...keep reading!"

Note the Topflite site has a free download available of the complete kit manual (48 pages) for this discontinued kit. Also page with full parts listing, and 2 further downloads of diecut sheet drawings. See

Boy do I remember this one. Spivey, notorious owner of one of the local hobby shops, sold one of these kits to a customer as his first airplane. He appeared at our field seeking help with the test flight, and I was selected. He did a real nice job with the construction and radio installation, even though it was a bit heavy with the shiny paint job applied by his buddy, an auto body man. A honkin' Enya 60, latest in their product line, ran well and produced tons of power, more than enough for the model. I ran it down the runway and gently lifted it off, whereupon it instantly tried to snap roll, all by itself. Somehow I was lucky enough to recover and get it leveled out and flying straight, but every time I so much as touched the elevator it tried to snap roll again. I gently flew it around until I could get it lined up for a landing and back on the runway, after a few more snap roll heart attacks. Then we started to look a little closer to find the source of the problem. I suspected too much elevator movement but inspection showed it to be about right, in the opinion of the assembled R/C'ers, a ring of tennis shoes surrounding the cooling model. When we looked closely at the severely tapered scale wing, the situation became obvious. Yes, you guessed it, he had built washin instead of washout into the wing, no way it was ever going to fly. The kit came with little shims to enable the wing to be built flat on the board, including the proper washout, but he had somehow done it backwards and ruined the whole project. Later I found out he had employed Dusty Shinn, long time club member to test fly it the week before, with similar results which he hadn't mentioned. I guess he thought Dusty just couldn't fly it. It was a truly beautiful model, so I told him to just hang it up and never fly it again, it would make a nice display piece. This is what happens when you try to build the wrong model as your first attempt. We never saw him again.

* 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.
