3.1 AIRPLANE WING TYPES (ACRO/GLID):
There are 3 basic wing types in MULTIROTOR 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 models (flying wing). Model uses 2 wing servos working together 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 travel 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 FLAPERON for level flight.
• Also allows aileron differential in its 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
