Use hook and loop material to hold the battery on the other side of the fuselage as shown below. This will
help with balancing.
Balance the Model
With the plane fully assembled and no fuel, lift the plane by the wings and check the balance point. The
center of gravity should be on the main spar that can be seen through the wing covering 1/3 back along the
wing root. Adjust the CG by adding stick on lead weights to the tail or the firewall as necessary. The CG
may be moved forward or back up to ½”. Do not attempt to fly the model if is not balanced as it will be
unstable and possibly uncontrollable. Balance the model laterally. With the model on a flat surface, lift it
quickly by the prop shaft and the tail. If one wing consistently drops, that side is heavy. Balance the plane
by adding weights to the lighter side.
Set the Control Throws
Turn on your transmitter and connect the battery to your speed control. Confirm that all controls operate in
the correct directions and as expected. Adjust your radio end points to achieve your desired throws. The
servos should move smoothly through their full range, without any excess noise. If the servos are straining
at the end of their travel, they will consume more battery power than expected, possibly shortening your
flight times.
Identify the Model
Label your model with your name and phone number or AMA number. This is an AMA policy and just
good practice.
Charge Batteries
Be certain that your transmitter and airplane batteries are fully charged. A weak battery can cause
unexpected or even complete loss of control. Be certain your batteries are fully charged.
Flying
Select a flying area that is large and grassy. School yards are not usually a good idea because of the
proximity of people and buildings. It should be at least 6 miles from buildings, streets and other RC
activities. The best place is at a sanctioned AMA club field. Contact the AMA for information on clubs
near you.
Ground Check
While still on the ground it is vital that you inspect your model for airworthiness. Double check all screws
and bolts for tightness. Check that control surfaces are secure. Check that the wing is secured and in place
correctly. Check the motor is in good working order. Confirm that the landing gear is secure. Check the
CG. When you are satisfied with the condition and assembly of the model proceed to the next step.
