About this Plan

Flattop Stormer - Radio control aerobatic model. Here is Doug Spreng's Flattop Stormer from American Modeler magazine issue 05-62.

Quote: - "Please notice that you are now offered two sizes of wing and two shapes of stabilizer. There is a long wing (64in sans tip) for those of you who are still freshmean in the art, and a short (60in without tips) one for you seniors that like a little zip in yer ship. I flew the long wing at the Nats. It rolls a little slower... The tapered stab is for you 'looks' buffs with well equipped workshops..."

The Svensen kit called this model Flattop Stormer, and power was 35 to 60 no muffler shown. I can just fly my plane with a ST45 and muffler. I went back to my Merco 61 with muffler and have a couple of oz of wt in the nose. Floats like a dream and can easily pull out of inverted loops in slow motion!! Still have original Merco 61, plans, box and plane from 40 years or so ago. Last flown 2 years ago carefully.

Hi Steve, Doug Spreng won the U.S Nationals in radio control Multi (as it was then called) twice in 1960 and 1961 with an airplane called Stormer. I had to build a Stormer. I started out building the Stormer and thought if I wanted to finish the plane in a reasonable amount of time, it would have to be a Flattop Stormer. Eliminating most of the carving and planking would shorten the building time and Doug said they both fly the same. I finished the plane with an old O.S. .40 for power. I then thought hey, this is a good flying plane why not electrify it so it will last longer. (no oil soaked balsa over time). Here are some pictures, then and now [more pics 003-005]. Once again, thank you so much for providing us with this great archive of model airplane plans.

Back in the early sixties, I lusted after the Stormer, popular with the Mobile club at the time. There was no way I could afford the required reed radio set it used, and my only building area was a drawing board in a bedroom shared with my brother, restricting my efforts to small single channel models. Club member Gene Mathis always had at least one Stormer ready to fly and another in progress. It flew soooo much better than most of the ARF stuff we see now. But Spreng has another claim to fame. He invented the servo circuit we still use today, developed for his Digicon system, the first commercially available digital radio. He never patented the circuit and all the rest of the radio systems immediately copied his idea. The basic idea has not changed in 50 years. You can take his original servo, change the plug and center-tapped battery, and it will work perfectly in a modern receiver, no need to adjust the centering. If I can find a few more round tuits, I'll have to finally build a Stormer.

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.
