SAIL Mixing

For each of these mixes, you can program each flight mode with
different mix values or at 0% if no mix is desired for that specific
flight mode. Programming values include independent control of
the direction and amount a slave surface moves in relationship
to the master surface.
Aileron to Rudder
The Aileron to Rudder mix is a commonly used for coordinated
turns. When active, as aileron is applied the rudder moves
generally in the same direction as the turn (right aileron input
results in right rudder output). If flight mode is selected as
a switch, a Sub Switch option allows another switch to be
programmed to select up to three aileron to rudder mix values
that will only be active in that flight mode.
The following mixes only operate with a Flap wing type in
Sailplane Type.
Aileron to Flap
The Aileron to Flap mix allows the entire trailing edge of the
wing (aileron and flap) to operate as ailerons. When active, as
aileron is applied the flaps also move. Always program the flaps
to move in the same direction as the turn (so that right aileron is
equivalent to flaps moving as right ailerons).

Elevator to Flap
Elevator to Flap mix creates more lift, allowing a tighter turn.
The entire trailing edge of the wing (aileron and flap) operate as
flaps (camber increase) when elevator is applied. An offset is
provided which is typically used for Snap Flaps. With Snap Flap,
no Elevator to Flap mix occurs until the offset value is reached.
Typically this offset is at 70% up elevator so that beyond 70%
the down flap mix comes in, providing additional lift for more
aggressive turning (for tight thermals or racing turns).
Flap to Elevator
Flap to Elevator mix prevents pitch up tendency that occurs
when brakes (Crow or Butterfly) are applied. This mix is typically
used only with the brake system (See Camber system). This mix
operates as a curve, so that the elevator typically moves down
most during the first 20% of flap deployment, decreases over the
next 40% then remains the same from 60 to 100% of flap travel.
For sailplane with ailerons/tips/flaps, make sure an appropriate
Sailplane Type is selected so that tips may be identified in the
transmitter as RAIL and LAIL. Decrease or increase travel on the
tip ailerons by creating an AIL > RAL mix. This is a standard way
to accomplish this function without causing effects on the travel
from other subsystems such as camber.

Receiver Installation

For optimum RF link performance, mount the main receiver
and remote antennas in an orientation that allows for the best
possible signal reception when the aircraft is in all possible at-
titudes and positions. Where supplied with the transmitter, install
the primary receiver in your model. Put the primary receiver
in protective foam and install the receiver in the model using
rubber bands or hook-and-loop straps. Use thick double-sided
foam tape to install the primary receiver in electric airplanes or
helicopters.
Mount each remote receiver at least 2 inches (51mm) away
from the primary receiver, primary antenna and each other using
double-sided foam tape. Orient the antennas perpendicular
to each other; typically one vertical and one horizontal (see
manufacturer's receiver installation instructions). This gives
tremendous improvements in path diversity as each receiver can
"see" a different RF environment. This is key to maintaining a
solid RF link, especially in aircraft that have substantial conduc-
tive materials (e.g., larger gas engines, carbon fiber, pipes, etc.),
which can weaken or block the signal.
In airplanes, we recommend mounting the primary receiver
in the center of the fuselage on the servo tray and the remote
receivers on the side of the fuselage or in the turtle deck (space
behind the canopy and in front of the vertical stabilizer).
In helicopters, install receivers in the radio tray, where there is
