Lightning Bug (oz2168)
About this Plan
Lightning Bug. Simple TeeDee .010 powered radio control design. Appeared in Model Airplane News in July of 1961.
Later kitted by Jetco.
Quote: "Since the advent of the Cox .010 engine planes are smaller and add to this combination the lightweight relayless receivers and we have 7-1/4 ounce R/C planes.
The first RC job we flew - designed by the writer, built by MAN's editor and chased on a 50-50 basis by the both of us - was an Ohlsson 60-powered behemoth that weighed a ton. Lightning Bug, the 40th RC, spans 26 inches and is powered by the new .010. It weighs less than the batteries did in the big job 13 years ago. Not half as much as did the Good Brothers receiver with its batteries.
Wing loading is 9-2/3 oz per square foot , power loading 725 ounces per cubic inch displacement, gross weight 7-1/4 ounces. Keep in mind when building yours that every extra ounce means another 100 ounces power loading!
There is nothing really sensational about an .01 RC. No freak, this one is built like any other RC. Proportions are normal and materials generously strong. At 7-3/4 ounces this model is 4-1/4 ounces heavier than the designer's free flight for the same engine, suggesting that weight cannot be reduced easily - there just isn't enough wood in the craft to permit any important saving. The radio is a Citizen-Ship LT 3 with the matching SN escapement that came in the same box.
Lightning Bug may be bigger than some .02 bombs, but it has roughly half the area of Ken Willard's .01 which, we hear, has about 200 squares. Recalling much that has been published about .02's, doctored escapements, and so on, for extreme lightness thought so necessary, one may wonder. The .01, half as big as the .02, definitely does not require doctoring anything in order to fly.
By careful building and material selection, the .01 can be pared to under seven ounces, but it climbs at 7-3/4. The thing to watch is extra weight... "

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.
