Adjusting the Climb Rate
If the airplane, 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 by one full
turn and loosening the rear tail screw by
one full turn.
2. Test fly.
3. Repeat the above procedure if necessary
until the Firebird Commander
®
2 climbs
adequately under full power.

Adding the Wing Shim

If the climb rate is still too steep after
making the tail screw adjustments on the
previous page, add the included wing shim.
1. Place the wing shim on top of the fuselage
at the rear of the wing saddle as shown.
2. Then, place the wing over the wing shim
and rubber band the wing to the fuselage
as normal.
Adding the wing shim will cause the Firebird
Commander
®
2 to climb less steeply and
reduce the tendency to repeatedly climb
and stall. Add the wing shim when the wind
is gusting more than 10 mph.
IMPORTANT: Adding the wing shim will
cause the Firebird Commander 2 to fly
faster, due to the wing’s reduced incidence
angle.

1mm Wing Shim
If the airplane climbs too fast with full throttle,
by climbing at a steep angle, stalling and
repeating climbing sharply and stalling, do
the following:
1. Loosen the front tail screw by one full turn
and tighten the rear screw by one full turn.
2. Test fly.
3. Repeat the above procedure if necessary
until your Firebird Commander 2 climbs
at a steady rate.
4. If, after making maximum adjustments,
your Firebird Commander 2 still climbs
too steeply, add the wing shim
(see page 23).
