About this Plan

My o My. Radio control sport model.

Quote: "That Old Timer free-flight models converted to R/C make superb primary trainers has been widely recognized for several years. These old designs with their light wing loadings and high degrees of inherent stability, coupled with slow velocities, and relatively large size, provide the rank beginner with an opportunity to learn the rudiments of pilotage with a minimum of risk. My personal experiences, as well as those of the numerous builders who have written me, indicate the Old Timer type of models to be nearly perfect as trainers for those who have never previously flown R/C. These same characteristics also make these light, slow and large models highly attractive as sports subjects.

Sadly, the average Old Tinier design is not easily constructed by the beginner. The design and construction of these model aircraft from the 1930's strongly reflects the state of the art of that era - one must remember that epoxy, aliphatic resin, the glow plug, nitroinethane fuel, heat shrink covering material, etc were not available to those pioneer designers. The extraordinary flying ability and lovely appearance of those old designs attest strongly to their designers high skill levels with the techniques and materials available to them. The fact, nonetheless, remains that newer building and designing techniques can be used to create model aircraft possessed of the desirable performance traits of these antiques, while vastly simplifying construction and improving the durability of the model.

The My-O-My is an attempt on my part to create an Old Timer R/C type model, utilizing modern adhesives, materials, and techniques, while retaining those highly desirable virtues previously mentioned. That the My-O-My weighs 14 ounces per square foot, flies well on low power, has exceptional stability, and is startingly easy to construct, leads me to feel that indeed she is a 'new' Old Timer.

Her lineage has been a source of amusement for me. There are those who say she is a semi-scale Pober Pixie, or a Baby Ace, or maybe an obscure Old Timer or home-built. Others see an enlarged Q-Tee or a shrunken something-or-other. My reply to each claim has been: You are absolutely right..."

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

* 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.
