Part 3. ACRO ADVANCE MENU FUNCTIONS
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
