The FOUR-STAR 40 is a fun aircraft to fly, but it is not a basic trainer. If you have no previous R/C flying experience, we
suggest that you not attempt to fly this model without the assistance of an experienced pilot. Contact your local club or ask
your hobby dealer for the names of good fliers in your area and a suitable location for flying.
Practice taxiing the model while holding "up" elevator to avoid nose-overs. When
you are ready for takeoff, point it into the wind and apply throttle. Release the "up"
elevator as it accelerates. You'll probably need a touch of right rudder to keep it
going straight because engine torque will try to make it drift to the left. When you
reach flying speed, pull back slightly on the elevator stick for a gentle liftoff.
If you are using a relatively large engine, don't expect the takeoff roll to last very long! With its big wing, the FOURSTAR 40
likes to jump into the air and get down to business! You will find the model capable of almost any trick "in the book".
Experiment With different control throws and balance points until the model flies exactly the way you want. Make any
changes, especially to the balance point, gradually. We recommend that you shift the balance point no more than 1/8" at a
time. In general, moving the balance point forward will make the model more stable, slowing down snap rolls and spins.
Moving the balance point back increases its sensitivity to control inputs; but if carried too far, the model can become
completely unstable and uncontrollable. The balance range shown on the plans is a "safe" area to use for test flights. Don't
exceed the rearward limit unless you are a very experienced pilot.
When landing, the FOUR-STAR 40 may tend to "float" a bit more than other models you have flown in the past, so be ready
to go around if it looks like you're going to overshoot the runway. It will take a few flights to get a feel for the correct
approach and landing speed. Remember to keep your control inputs smooth and gentle to avoid overcontrolling.
When you are certain the model will make it to the runway (even if the engine
quits), bring the throttle to full idle and concentrate on keeping the wings level
during final approach. Slow the model down during the entire approach by slowly
feeding in up elevator. Just before the model touches, flare the landing by
carefully feeding in more up elevator. Hold the model just inches off the ground
until your elevator stick is pulled all the way back. The FOUR-STAR 40 should
settle in for a perfect "threepoint" landing with a short rollout. Oh, and when you
taxi back to the flight line, don't be surprised if there's already a line of R/C pilots
wanting to fly your new SIG airplane!
The top view and side view drawings are provided for modelers who wish to to develop their own personalized color and
trim scheme for the FOUR-STAR 40. Make several copies of this page so you can draw out a few different ideas before
deciding which one you like best.
