These plans for the Fleetwon control line combat model was sort of crammed into the 1960 Annual edition of Air Trails magazine. I say that because the article accompanying it is rather terse, and there are no photos of the actual built model. Bob Peru designed it for a .35 size engine, but says it can get along with a .19 if ultimate performance is not required. Wingspan is about 38", so a .19 would definitely be on the low side for power unless the model is built extremely light. Construction employs a typical balsa main framework with plywood and hardwood used for engine and bellcrank support.

Fleetwon Control Line Combat Model

East Coast Control Line Combat Model

By Bob Peru

After the smoke clears away and the tattered streamers and balsa chips are swept from the combat circle, do you wonder what happened? Did your ship perform like a lead balloon? - Well, wait 'til next time - Resolved - that next combat ship has to be simple, easily built, low in cost, have red-hot performance and be expendable.

Fleetwon was designed with these requirements in mind. It has no fancy frills, just the bare essentials. It utilizes standard size wood and can be built in four or five hours. A minimum amount of wood is needed for its construction, a "must" since the price of balsa has recently increased. The design is a compromise all around, truly a happy medium. Though some smaller ships may be slightly faster their maneuverability suffers. Larger ships may turn a bit tighter but their speed suffers. This flying wing design behind a hot .35 engine will leave little to be desired in the performance department.

The K&B .35 engine was used with great success on original models but since you may use a different engine, be sure to balance model at spar by shifting engine along bearers to get proper mounting location. The correct C.G. location is most important on any flying wing model so do not depart from C.G. range as shown on plans. A forward C.G. position will make model sluggish in tight turns while rearward C.G. will make model very sensitive. If a .19 engine is to be used the engine bearers should be made an inch longer so that engine weight may be shifted forward to get proper balance (text was misplaced at end of final paragraph in original).

Use firm light wood throughout construction of Fleetwon. Final weight should be about 18-20 oz. This gives the model a light wing loading of 5 oz./100 sq. in. This low figure permits speeds in excess of 80 mph and red hot maneuverability. For best results do not depart from construction shown on plans, be sure structure is square [with no] warped wings.
