Attention
EDF jets require Li-PO batteries with a high discharge rating (C rating) for increased safety and
optimal performance. We recommend using Li-Po batteries with a minimum of 40C or above.

Control Direction Test
Assemble the aircraft and bind your transmitter to the receiver before performing this test
to the aircraft receiver, set the trims and sub-trims to 0, then adjust the clevises to center the control surfaces. Move
the controls on the transmitter to make sure the aircraft control surfaces move in the proper direction.

Control Surface Centering
*After assembly and transmitter setup, verify that the
contro.l surfaces are centered. If the control surfaces
are not centered, manually cen.ter the control surfaces by
adjusting the linkages.
*With the flaps switch in the up position, flaps should be
adjusted so that they are even with the ailerons/root of
the wing.
*If adjustments are required, turn the ball buckle on the
push rode to change the length of the linkage between
the servo arm and the control horn. After binding the
transmitter to the receiver, set the trim and sub-trims to
0, then adjust the ball buckles as necessary to center
the control surfaces.

Step 4: After the 'beep-beep' tone is emitted, move the throttle stick back down to the lowest
position (0%). You will then hear a set of initialization beeps that register the number of cells in
the battery
Step 5: A final long beep tone should sound, meaning that the lowest point of the throttle range
has been confirmed. This means the throttle control has been initialized properly and is ready
