Normal and Stunt Flight Modes
The Spektrum DX6i transmitter included with your Blade 400 3D features a Flight Mode (F. MODE)
switch. This switch allows the pilot to toggle between the “Normal” (0) and “Stunt/Idle Up” (1) flight
modes during flight.
When the Flight Mode switch is toggled toward the rear of the transmitter (position 0), the Blade 400
3D will be in the Normal (NORM) flight mode. In this flight mode, the throttle curve is linear from 0%
to 100%, with a pitch range of approximately -3 degrees (35%) to +10 degrees (100%). This is the
preferred flight mode for general hovering and basic (non-aerobatic) flight.
When the Flight Mode switch is toggled toward the front of the transmitter (position 1), the Blade 400
3D will be in the Stunt/Idle Up (STUNT) flight mode. In this flight mode, the throttle curve is “V” shaped
from 100% to 100% with 85% throttle at mid-stick, with a pitch range of -10 (0%) to +10 degrees
(100%). This is the preferred flight mode for most forward/backward, aerobatic and 3D flying.
Note: When in the Stunt flight mode, even with the throttle stick pulled all the way down to its
lowest possible position, the motor and rotor blades will continue to spin aggressively. You must
use the Normal flight mode (or Throttle Hold) to safely power down the motor and rotor blades. For
added safety, the ESC will not arm if the flight battery is plugged in and the flight mode switch is set
to the Stunt position.
When switching between the Normal and Stunt flight modes, it is typically best to do so in the air while
hovering. The throttle and pitch curves of each flight mode have been optimized to transition smoothly
around hover.
Note: Although the midpoint (point 3) of the throttle curve in the Stunt flight mode has been factory-
set to 85% to provide good overall sport and 3D aerobatic performance, this value (as well as the
values for points 2 and 4) can easily be adjusted to better suit the pilot’s preference. Pilots new to
this class of model, or those that may not require the most aggressive performance, may prefer to
reduce the value of the midpoint to approximately 70%. This will reduce the headspeed in upright
and inverted hover, as well as at mid-stick, often times helping to make it easier (smoother) and less
intimidating to fly the model. However, if you reduce the value of the midpoint (point 3), it will also
be necessary to adjust the values of points 2 and 4 in order to achieve the best performance. In
