Scale Documentation. Orin Mumphries (Spokane, WA) sent in a letter in which he spoke about one of his favorite subjects - that of proper scale documentation. Orin spoke of the need for Scale modelers to be especially careful when interpreting three-view drawings and applying that interpretation to the building of a Scale model. He points out that drawings are not always accurate, even though they come from sources that appear to be beyond reproach. In fact, there are many instances when a modeler finishes a model based on a set of three-views, and is very disappointed when he finds out, at a contest, that his plane did not measure up.

BIGGER is not always better-Dave Mullens, Seattle, WA (editor of the Seattle Skyraiders' Newsletter) sent in a report of the Raiders Round-Up; their 1982 Washington State Control Line Championships. Of interest in the report was an item that shows us still another approach toward Scale competition. At last year's fall meet, the Skyraiders ran, in addition to regular AMA Scale events, a local event called Sorta-Scale, which Dave describes as a very relaxed form of Sport Scale. The event is one in which the entries are not the usual large, heavy, and well-powered models we have become accustomed to seeing at our local contests. Just the reverse, in this case! The heaviest model in this past year's Skyraider Sorta-Scale event was a 31/4-lb. ME 109, and the lightest was an 18-oz. P-47. The accompanying photos show both of these planes, and in addition, an excellent Bucker Jungmeister that weighed in at a very heavy 20 oz. Flying wires for the models ranged from 35 to 60 ft.

BASIC TIPS (continued). In the last month's column I discussed problems related to the building and flying of a Ryan STA model built by Dave Mullens of Seattle, WA. The problems presented were proper installation of wheels in wheel pants and model tracking while taxiing. Another of Dave's problems that I didn't get to last month was that of an overheating engine in this particular model. While I will comment on the Ryan problem, I would also like to cover other types of planes and, perhaps, suggest some ways of coping with engine cooling problems. I have reviewed the Ryan STA project and, barring the use of a new engine (one not broken-in), I find that engine cooling should not be a major problem. A new, improperly broken-in engine can cause overheating under the best of circumstances.

NEW FAI CL Scale rules. Those of you that might be interested in building and flying in the FAI CL Scale event should take particular notice of rules changes that become effective January 1, 1984. A complete listing and full explanation of the rules changes was published in the May 1983 issue of Model Aviation in the "Competition Newsletter" section starting on Page 113.

DURING the past year, I have presented various subjects contributed by many of you. Another task I have undertaken while responding to your input has been the answering of many questions on a personal basis. After looking over some of the questions and answers of this past year, I decided that there might be many of you reading the column who would also be interested in the same subjects. Therefore, the bulk of this month's column will be dedicated to a series of questions proposed by John Patrolia (Marshfield, MA) and other members of the Hanson Wingbuster MAC, who are just starting in CL Sport Scale.
