A plane's weight determines how much power it needs. If your ship is huskier than average, it may not climb, even when fully
wound. In that case, add one strand (not a complete loop) of 1/8" Sig rubber to the motor. Tie an eye (like a slip knot) in each
end. This will provide the extra horse power needed for higher climb.
Whenever you add rubber, re-balance your model as outlined in the pre-flight instructions. Additional rubber tends to make a
plane tail heavy.
Take-Offs
When your Classic has been adjusted according to instructions, it should have no trouble taking off by itself from a smooth
surface. No adjustment changes should be necessary. You may find that take-offs are better if you release the ship pointed at a
slight angle to the wind instead of headed straight into it. Experiment to find the best system.
Rubber Motor Hints
The rubber motor in your Classic kit will safely give you a whole season of flying if you stick to the chart. "Hand Wound" means
winding the propeller with your finger while the rubber is inside of the fuselage. "Stretch winding" is a more complicated two-
man operation, but gives longer flights.
Before a motor can be safely stretch wound, it must be lubricated. Rub a few drops of Sig Rubber lubricant into the rubber
(AFTER the knot has been securely tied). Use just enough to make the motor barely damp. If it's too juicy, it will splatter all over
the inside of the fuselage. Next, make a strong wire hook, like a teacup hook, and lock it VERY TIGHTLY in the chuck of a hand
drill.
Then, while your helper holds the model by the rear rubber peg and the
cowling, stretch the motor out the front of the model to about twice its
normal length, unhook the propeller, hook up the winder, and wind while
slowly walking back toward the plane.
All the models in Sig's Classic series have been carefully designed and
flight tested to assure flying ability. Hand wound, you can expect flights of
10 to 25 seconds and stretch wound, 20 to 50 seconds. Like model
builders, some of the designs have more ability than others, but all are
proven dependable flyers.
A Classic flying model is not a ready-to-fly toy. Your skill in building and
flying DOES make a difference. So whether your flights are short or long,
you can be proud of completing a job which was successful because of
your own effort and ability.
Good Flying!
