Making Adjustments to the Climb Rate
A. If the Aerobird Challenger
™
(with a fully charged
battery) does not climb fast enough with full throttle,
you can adjust the climb rate by:
1. Tightening the front tail screw in one full turn
and loosening the rear tail screw one full turn.
2. Test fly.
3. Repeat the above procedure if necessary until
the Aerobird Challenger climbs adequately
under full power.
B. If the Aerobird Challenger climbs too fast with
full throttle by climbing at a steep angle, stalling
and keeps repeating climbing sharply and stalling,
do the following:
1. Loosen the front tail screw one full turn and
tighten the rear screw one full turn.
2. Test fly.
3. Repeat the above procedure if necessary until
your Aerobird Challenger climbs at a steady
rate.

Note: Only use this option if you do not have
enough travel with the trim lever to the left of
the control stick or if you would like to fine-
tune the flight characteristics with the trim
levers and controls in the neutral position.
A. If the Aerobird Challenger
™
keeps turning to
the left and adjusting the trim control lever
(page 20) does not correct enough to fly
straight with the stick at neutral:
1. Adjust the control line so that the left tail flap
is 1/16" above the rest of the tail surface.
2. Test fly.
3. If it still flies to the left, repeat the above
procedure, adding 1/16" each time until it
flies straight.
B. If the Aerobird Challenger keeps turning to the
right and adjusting the trim control lever (page
20) does not correct enough to fly straight with
the stick at neutral:
1. Adjust the control line so that the right tail flap
is 1/16" above the rest of the tail surface.
2. Test fly.
3. If it still flies to the right, repeat the above pro-
cedure, adding 1/16" each time until it flies
straight.
IMPORTANT: If there is a bend (even a small one) in the tail or wing or a tear near the flap areas, it is
impossible to have correct flight control. Replace the damaged part immediately!
