Transmitter Setup
CAUTION:
For safe operation, always re-bind the airplane after setup is
complete to ensure the failsafe is updated with the latest setup.
A DSM2/DSMX six-channel (or better) computerized transmitter with adjust-
able dual rates, expo, delta/elevon mixing and programmable mixing for vector
thrust is recommended for fl ying the E-fl ite Scimitar. DX6i, DX7s, DX8, 9503,
11X or 12X transmitters may be used.
Flying wings are controlled by elevons (moveable surfaces on the wing).
Elevons take the aileron control (move opposite directions), and elevator control
(move up/down same direction) and mixes them together electronically through
the transmitter. Make sure both elevons move up and down (travel) the same
amount. This model tracks well when the left and right elevons travel the same
amount in response to the control stick.
Differential
This model requires differential. Differential is important for good axial roll. Set
the differential in your transmitter to reach the recommended throw for the
Scimitar elevons (described in control throws as Aileron/Elevator).
Vectored Thrust (VT) Mixing
Make sure the VT servo is connected to the Aux 1 port of the receiver. Set up a
programmable mix of Rudder to Aux 1 (channel 6). Use linear mixing and adjust
the mix to reach maximum travel of the VT unit. (See next page for adjustment
of maximum throws.) Select a switch to power on and off this mix. Use this
switch to help you get familiar with the VT.
Make sure the vectored thrust (VT) is at neutral when mixing is on or off. Make
sure both rudders are perfectly neutral.
Aileron Trim or Throttle to Aileron Mixing
Due to the high torque required to support the Scimitar fl ight envelope, the
torque effect tends to make the model roll left as power is increased. It is
recommended before takeoff to adjust the aileron trim to compensate for this
torque. After the Scimitar’s ailerons are centered, add between
1
and
1.5mm
of right aileron trim to your transmitter. On the Spektrum DX8, this translates
to approximately 8 clicks of right aileron trim when using the default trim rate.
Download Quique’s DX8 program, which includes throttle to aileron mix in
order to compensate for the torque (letting you keep aileron trim at the neutral
position).
Fly the model at factory settings before making changes. For pilots who wish
for more control throw, adjust the position of linkages on servo arms and
control horns for increased travel.

Transmitter Setup Checklist
Before binding:
1. Choose a blank model memory with only default (zero) set-
tings (including trim and sub-trim).
2. Choose Wing Type as Delta Wing or Elevons.
3. Set servo reversing (as recommended on this page for your
transmitter).
After binding:
1.
Check and adjust the servos so each arm’s neutral position
is perpendicular or as close to 90° as possible (loosen and
adjust the servo arm splines on the servo only when needed).
Use sub-trim to make fi ne adjustments.
2.
Adjust linkage lengths so the control surfaces center when
the servo arm is perpendicular.
3.
Set rates in the transmitter as recommended by measuring
the control surfaces and Vectored Thrust (VT).
4.
Set the Differential (as recommended by measuring travel for
both ailerons).
We recommend this setup for servo channel reversing for the DX7,
DX7S and DX8 transmitters ( Same for JR9303/9503, 11X and 12X ):
Throttle:
Normal
Aileron:
Reverse
Elevator:
Reverse
Rudder:
Normal
For the DX6i, we recommend this setup for servo channel reversing:
Throttle:
Normal
Aileron:
Reverse
Elevator:
Normal
Rudder:
Normal
NOTICE:
When setting up the model for control using a Spectrum DX6i
transmitter, swap servo connections between the aileron and elevator
ports on the receiver (from factory settings). Do a control test to make
sure the model operates correctly.
CAUTION:
Make sure the rudder and VT travel in the same direction.
If the VT unit and rudder travel in opposite directions, the propeller will
touch the rudders and damage them, causing the airplane to crash.
