A bit of trivia about the Cox Chipmonk. There were three versions, (the same for the ME-109.) The first was a hollow sheet foam wing version that had the wings fold at the leading edge, and were taped at the trailing edge, then plugged onto a stub wing root and held on with tape. I think these were lighter, and flew better, but were pretty fragile. Extra wing sets were available with plans for a Focke-Wulf 190 plan for them also. The seciond version came out like the pone pictured. Ted Fancher did a review of the plane in his Model Aviation column. This was back in the early to mid eighties I think. Ted had some suggested modifications that included moving the leadout guide forward, and adding tip weight. That second version had a specific part number. I had one at the time and tried Ted's modifications and they worked well. Cox took the suggestions seriously and incorporated them into future production models, with a totally new part number for the model. The model was very capable of the entire pattern, it just took a couple three tanks full of fuel to do it! Using the stock engine mount and back plate, if you added a twin bypass port cylinder of any late model Cox engine with SPI, a good reed fit, 25% nitro fuel, and the proper prop, that is all that is needed for decent performance. You would have to modify the fuselage to carry a tank big enough to do the whole pattern. Not sure what that would do to the weight and balance of the airplane. The foam Cox stunters are on my list of Cox RTF's to get into teh air this summer!
