Hate to be the bearer of bad news, I believe none of these Midwest kits are legal for classic. The first plane to appear in print was the King Cobra, then the ME 109, these came out in May and June 1969. I have built 3 109s, a Tony and one kit Cobra. The Tony was published in early 1970 Flying Models. Flying Models numbered their plans I beleive in the order they received the articles but didn't publish them in the order they were received. The Tony is CF-177 and Dick Mathis's 1000 Grand FF design is CF-178, published in Feb 67. Also there are many typos in Flying Models. Jack Sheeks ME 109 is listed in the Scale RC section as CF-185, 4-70 FM and was fixed by 1974. All these planes use the same basic wing, the kit wings are different, I think they are a bit smaller with a thinner airfoil and a different LE. The kits appeared on the market late 1970 and early 1971 around Christmas time. The Mustang was the last of the series and was marketed in 1971 near the end of summer, it was never a published design. Also there are some changes from the original plans verses the kit plans. If these planes are scratch built they seem to be lighter. Bill Darkow loved the kit version of the Cobra. The Tony has LG mounted in the wing and should be beefed up a bit as it will rip out easily on grass. I used an Enya .35 with half the venturi plugged on one 109 and the last one had a Max 35s. I hadn't flown cl for years and decided to take it out, the last 109 was built in the early 1980s, one evening. After the crash the lines I used said 60ft, when measured they were 72ft. Lesson on that one is still fresh. If you are an intermediate flyer and wanted to fly in classic I would bet no one would care that much. I would like to see some designs added to the list of OT and classic models, as no one is going to build them if they aren't "winners", the designs would continue to be "kept" alive. This series of planes are still favorites and will be for some time. They are still great flyers, all of mine had Moneycote on them and painted bodies. Jim J.
