ACRO ADVANCE MENU FUNCTIONS:
Aircraft wing types (ACRO):
There are 3 basic wing types in aircraft models:
v 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.
v Twin Aileron Servos. Model uses 2 aileron servos and has a tail. see Twin Aileron Servos.
v Tail-less model (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): Many current generation models use two aileron servos, plugged into two
separate receiver channels. (If your model is a flying wing without separate elevators, see ELEVON, p. 44.)
Benefits:
v Ability to adjust each servo's center and end points for perfectly matched travel.
v Redundancy, for example in case of a servo failure or mid-air collision.
v Ease of assembly and more torque per surface by not requiring torque rods for a single servo to drive 2 surfaces.
v Having more up aileron travel than down travel for straighter rolls – aileron differential. (see glossary for definition.)
v Using the two ailerons not only as ailerons but also as flaps, in which case they are called flaperons.
Options:
v 5-channel receiver. Set up AIL-2 (see p. 42) in FLAPERON.
v FLAPERON:
v Uses CH6 for the second servo (see AIL-2 to use CH5 orCH7.)
v Allows flap action as well as aileron action from the ailerons.
v Provides FLAP-TRIM function to adjust the neutral point of the flaperons for level flight.
v Also allows aileron di
Channel 6 = normal flaperons, 2 servos operate together as flaps;
Channel 5 or 7 = act like aileron differential did in prior radios; channel 6 is still FLAPS, and the 2 ailerons
never act together as flaps EXCEPT in the airbrake function.
fferential in its own programming.
NOTE: Only one of the two wing-type functions (FLAPERON and ELEVON) can be used at a time. Both functions
cannot be activated simultaneously. To activate a different wing type, the first must be inhibited.
