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 ??????
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, warped wings made an inch longer so that engine weight may be shifted
forward to get proper balance.
