Part 3. ACRO ADVANCE MENU FUNCTIONS
3.1 AIRPLANE WING TYPES (ACRO/GLID):
There are 3 basic wing types in aircraft models:
• Simple. Model uses one aileron servo (or multiple servos on a Y-harness into a single receiver channel) and
has a tail. This is the default setup and requires no specialized wing programming.
• Twin Aileron Servos. Model uses 2 aileron servos and has a tail. See TWIN AILERON SERVOS.
• Tail-less model (flying wing). Model uses 2 wing servos working t ogether to create both roll and pitch
control. See ELEVON.
Twin Aileron Servos (with a tail) (ACRO/GLID): Many current generation models use two aileron servos,
plugged into two aileron servos, plugged into two separate receiver channels. (If your model is a flying wing
without separate elevators, see ELEVON)
ADVANTAGE:
• Ability to adjust each servo's center and end points for perfectly matched travel.
• Redundancy, for example in case of a servo failure or mid-air collision.
• Ease of assembly and more torque per surface by not requiring torque rods for a single servo to drive 2
surfaces.
• Ease of assembly and more torque per surface by not requiring torque rods for a single servo to drive 2
surfaces.
• Having more up aileron travel than down t ravel for straighter rolls, aileron differential. (see glossary for
definition.)
• Set a negative percentage to reverse the operation of one of the servos.
Options:
• 5-channel receiver. Set up AILE-2 prior to continuing with FLAPERON or AIL-DIFF.
• FLAPERON:
•Uses CH6 for the second servo
• Allows flap action as well as aileron action from the ailerons.
• Provides FLAP-TRIM function to adjust the neutral point of the flaperons for level flight.
• Also allows aileron differential in i ts own programming (instead of activating AIL-DIFF).
• Uses CH7 for the 2nd servo (see AIL-2 use CH5)
• Leaves CH5 & CH6 free for flap operation, such as flaperon and flap action together, in AIRBRAKE.
• Allows for more up aileron travel than down for straighter rolls. You will need to choose which of
FLAPERON or AIL-DIFF is better for your model's setup. If you need the ailerons to also operate as flaps,
you most likely want to use FLAPRON. If your model has 2 aileron servos and flaps, then AIL-DIFF is
probably the easiest choice.
NOTE: Only one of the three wing-type functions (FLAPERON, AIL-DIFF, and ELEVON) can be used at a
time. All three functions cannot be activated simultaneously. To activate a different wing type, the first must
be deactivated.
3.2
TWIN AILERON SERVOS (5-channel receiver, AILE-2 , ACRO/GLID)
AILE-2 allows FLAPERON and AIL-DIFF with a 5-channel receiver. AILE-2 only tells the radio that you
are using CH5 and CH6 (FLAPERON), or CH5 and CH7 (AILDIFF), not CH6 or CH7, as the second servo
in FLAPERON or AILE-DIFF. You still must activate and set up the FLAPERON/AILE-DIFF function.
Note that selecting CH6&5 or CH7&5 does NOT free up CH6 or CH7 to be used for other functions
when using a receiver with more than 5 channels. Both 5 and 6 (FLAPERON/AILE-DIFF) are dedicated to
the FLAPERON or AILE-DIFF programming. [This is beneficial with four aileron servos that need to have
their end points or sub-trims set separately. CH1, CH5 and CH6 are already fully set up to operate as ailerons.
Mix the CH7 or CH8 (the second aileron servo on the other side) into ailerons to function properly.
