3. Continue holding the desired digital trim button down and
turn the transmitter on.
4. Hold the digital trim buttons down for about five seconds
until hearing tones, which confirm the selection.
5. Connect the flight battery. Complete the flight control test,
confirming that all surfaces operate in the correct direction.
Stock Control Throw
Out of the box, your Champ should have the approximate control
throws. In production, this can vary by approximately 2mm
without any effect on flight performance.
5mm
6mm
High Rate Low Rate
Elevator 5mm up/down 3mm up/down
Rudder 6mm left/right 4mm left/right
With the battery installed, the center of gravity is approximately
28mm as measured back from the leading edge of the wing.
This can vary by approximately 1 to 2mm.

Choosing a Flying Area
When ready for your first flight, select a relatively open area, the
size of a basketball court or larger, that is free of people and
obstructions with calm wind (if flown outdoors). Once you have
properly trimmed your airplane and become familiar with its
handling and capabilities, you will be able to fly in other smaller,
less open areas. Larger open areas are preferred for first flights.
Flying the Champ
Use the low-rate settings for your first flight to become familiar
with the flying characteristics before increasing the throw of the
control surfaces (see page 10 Transmitter Dual Rate Function).
Place the Champ in position for takeoff (facing into the wind if
flying outdoors). Gradually increase the throttle to ½ to ¾ and
steer with the rudder. Once the Champ reaches flying speed it
lifts off on its own. The Champ climbs with ¾ to full throttle, and
roughly ½ throttle allows the Champ to fly without climbing or
descending.
Note: If at any time you become disoriented or get in
trouble, pull the power all the way off and
release the controls. The Champ will stabilize
into a steady gliding decent.
1. After launching, your Champ will climb at full throttle. Keep
the throttle ¾ to full on until reaching a safe altitude. At this
same time, make sure you are keeping the airplane steady,
directed on its intended path.
2. Make necessary right and left adjustments to keep the plane
on course. After reaching 4–6 feet of altitude, you can make
the directional changes you desire.
3. Remember—the Champ is a small, lightweight aircraft. Do
not allow the plane to get too far away from you. When the
plane is farther away from you it is harder to see and could
cause you to lose orientation.
4. Avoid holding the stick full right or left for more than two
seconds. This will cause the plane to enter a spiral and
could threaten your Champ.
5. Do not try to climb too fast by pulling all the way back on
the stick (up elevator), or your plane may enter into a stall.
Instead, climb by giving small amounts of elevator or by
increasing throttle.
6. Damage/bends to the wings or tail can greatly affect flight
control. Repair or replace damaged parts immediately.
Sharp Turns
In order to make a sharper turn, move the stick in the desired
direction and add some up elevator (pull back on the stick). The
plane will make a sharper banking turn.
Note: With the throttle set at low or off (gliding), the plane
will not turn as fast as when you are flying at or near
full throttle.
Rudder Trim
If the model wants to constantly turn one direction, use the
digital trim buttons to correct. Your Champ should fly straight
with the control stick at neutral. Always make trim changes in
one-click intervals.
