First Test Flight
The Four-Star 20 is a fun airplane 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 R/C pilot. Contact your local
R/C club or ask your hobby dealer for the names of good fliers in your area and
a suitable location for flying.
Choose a calm day with little or no wind for the Four-Star 20's first test flight.
This is important in getting the model properly trimmed. If there is too much
wind, you won't get a true reading on what the model is doing in the air.
The Four-Star 20 is capable of taking off from any smooth surface runway or a
closely cut grass field. The Four-Star 20 can also be easily hand-launched if the
grass is too long at your flying field. When hand launching, the airplane must be
launched straight and level directly into the wind, with the nose aimed at a point on the ground about 75' in front of you.
Never launch the model with the nose pointed up or the wings tipped to one side or the other. The launch should be firm
enough to achieve flight speed but yet not overly hard.
You will find the Four-Star 20 capable of almost any trick "in the book". Experiment with different control throws and
balance points until the models 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 the snap rolls and spins. Moving the balance point rearward
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 plan is a safe area to use for test flights. Don't exceed the rearward limit
unless you are a very experienced pilot.
Caution: Never land your airplane in tall grass or weeds with the electric motor running. Always throttle back completely if
you land in such terrain, or if you nose over after landing. Tall grass or a nose over will stall the motor if it is running. A
stalled motor can overheat the ESC and batteries, causing them to fail.
Join The Club
Although the Four-Star 20 is small and can be flown in fairly confined spaces by accomplished pilots, it should never be
flown within five miles of an organized R/C aircraft flying site. This one simple precaution can prevent the loss of your
model from radio interference. Do yourself a favor and join your local R/C club - you'll almost always get assistance and
good advice, and you will even make a friend or two!
GOOD LUCK AND HAPPY LANDINGS!
WARNING! THIS IS NOT A TOY!
Flying machines of any form, either model-size or full-size, are not toys! Because of the speeds that airplanes must
achieve in order to fly, they are capable of causing serious bodily harm and property damage if they crash.
IT IS YOUR RESPONSIBILITY AND YOURS ALONE to assemble this model airplane correctly according to the plans
and instructions, to ground test the finished model be fore each flight to make sure it is completely airworthy, and to
always fly your model in a safe location and in a safe manner. The first test flights should only be made by an
experienced R/C flyer, familiar with high performance R/C aircraft.
The governing body for radio-control model airplanes in the United States is the ACADEMY OF MODEL
AERONAUTICS, commonly called the AMA. The AMA SAFETY CODE provides guidelines for the safe operation of R/C
model airplanes. While AMA membership is not necessarily mandatory, it is required by most R/C flying clubs in the U.S.
and provides you with important liability insurance in case your R/C model should ever cause serious property damage
or personal injury to someone else. For more information, contact:
