ABRK — Airbrake Function
The
ABRK
function, when activated, simultaneously moves the flaps and offsets the elevator,
and may be used to make steep descents or limit airspeed in dives. All the controls move to the
defined positions by flipping the airbrake switch downwards. Normally, with a single flap, the
flap is dropped. With flaperons, you’ll want to raise both to prevent tip-stalling, but you may
experiment with small values of down flaperons to slow the model down.
When the airbrake function is active, both ailerons’ travel is set by a single number. The
elevator offset should be chosen to maintain trim when the airbrake function is turned on and the
ailerons rise.
Setting up Airbrake function
1. Use the up or down arrow keys to select the
ABRK
window.
2. Press the
CURSOR
key twice to get to the activation setting. The
INH
indicator will flash on and off.
3. Now press the (+) key to enable the airbrake function. Depending on the
position of the airbrake switch, the display will show a flashing OFF or ON.
4. First the amount of elevator offset is programmed. Press the
CURSOR
one
time. A small arrow is displayed under the numeral 2 (representing
elevator), and the percent sign will blink on and off. You may adjust the amount of travel
with the (+) and (–) keys. You may use anywhere between -100% and +100%, but the
default value of -10% is the recommended starting value. Be careful setting elevator offset,
as this has a very powerful effect on the model’s trim. Press both the (+) and (–)
simultaneously if you wish to reset to -10%.
5. To get to the flap travel setting, press the
CURSOR
key. A small triangle is
now displayed underneath the numeral 6, indicating the flap channel. In
addition, the percent indicator will flash on and off. You may input any desired flap travel
with the (+) and (–) keys. Although the default is -50%, you may set this anywhere from -
100 to +100%. You may return to the default settings by hitting both the (+) and (–) keys
together.
Note: if you have the flaperon function active, the
ABRK
function will cause both flaperons to
move. Be very cautious with large flap settings, as they may reduce the aileron authority
when you are flying slowly.
