About this Plan

Sub Scale Strato Streak. Free flight power model for .010 engines.

Quote: "Interest in high-performance .010 free flight continues to grow. This replica of a 1941 favorite can easily hold its own against contemporary designs.

In the December 1941 issue of Model Airplane News, Louis Garami introduced his Atom .09 powered Strato Streak (oz67). The Atom was, of course, a spark ignition engine, so a coil, condenser and batteries were part of the payload. Flying weight was in the vicinity of 12-1/2 ounces.

Now, over half a century later, we present a tiny clone with a Cox .010 screaming away up front, hauling a ship that at just 1-3/4 ounces weighs less than the pair of pencell batteries the Atom needed!

Shortly after WWII the gent who designed the Atom, Ray Arden, gave us the much more powerful Arden .09, also spark ignition. Then, for an encore, he gave us the glow plug, and spark ignition model engines all but disappeared. It was about 1948, while a student at the University of Kansas, that one of our Jayhawk Sundusters model club members decided to replace the Atom in his Strato Streak with the hot Arden and the Strato Streak became a fantastic performer.

Among the happier experiences of the times was an association with the grand old man, CO Wright of nearby Topeka, Kansas. Mr Wright was at one time AMA president and we younger modelers looked to him for guidance. Well, we did and we didn't. Three of us - Jack Jella, Stinson Smith and I - showed up at a 1948 contest in Independence, Missouri with our pristine Arden powered Strato Streaks. CO lectured us on the fact that a high center of lateral area (all of the vertical surfaces Mr Garami elected to add wherever he found a place) was bad news, and so the Strato Streak was a very poor design. Trouble was, the Missouri thermals had not attended the class on excess CLA, and we placed 1st, 2nd and 3rd in Class A that day. Smart aleck youngsters that we were, we (respectfully) kept the incident alive at any subsequent discussion on free flight design.

Today, as part of the Old Timer movement, the full-size Strato Streak with an ignition Arden continues to hold its own in competition. The design has become even more successful as an .020 replica. It remains to be seen whether a third generation can prove itself with an .010.

If you have ever built a stick-and-tissue model airplane, the simplicityof design of the Streak should charm you into a new free flight experience. For the fuselage longerons, we elected to use the laminated stick technique so popular with Peanut wingtips, however, 3/32 square and curved balsa sheet front and back should be fine if the laminations don't appeal to you.

A template is the starting place for laminated construction. Spray a piece of 1/16- inch thick illustration board with contact cement and attach the plan. With a knife and #11 blade, cut to the inside of the black fuselage outline, yielding a template. Rub the outside with a wax candle or piece of paraffin..."

Hi! I haven't sent you anything for a long time, so I decided to send some old photos that already have a plan in OZ, first about the Strato Streak, oz 12623 [main pic, 003-005]. Years ago my son decided to build one with the idea of competing in Old Time 1/2A Texaco and got a fabulous model and long engine time of the Cox Babe Bee. As expected the model we lost it in height after having flown it many times. I climbed for more than five minutes, where would I be?
Take care, the Covid does not forgive, a hug,

* 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.
