Flying with SAFE
First Test Flight
If not done already, for the first flight keep SAFE
parameters like tail gyro gain, cyclic gain, etc.
If the heli is setup well, you can familiarize yourself with the effect of SAFE
this we suggest to use the "Bail out rescue mode." Fly the helicopter in a sufficient amount of
height in a stable hover and activate the SAFE
The helicopter should continue to hover in approximately the same position. Now give some
aileron or elevator stick input and release the stick when the helicopter reached some oblique
position. SAFE technology should bring the helicopter back to the horizontal position more
®
or less rapidly.
Deactivate SAFE technology and again tilt the helicopter by giving some stick input. The
®
helicopter will stay tilted if you release the stick. Only when SAFE
flipping the switch again, the helicopter will be rotated back to its previous horizontal position.
If using a SAFE
throttle stick does not have any effect in some area as SAFE
collective pitch control as long as the throttle stick is in this area and SAFE
is activated. Therefore, verify the throttle stick is in a position that will roughly produce
the same amount of collective pitch, before and while deactivating SAFE
Otherwise when deactivating SAFE
if the throttle stick controls a smaller pitch angle than SAFE
you can optionally enable a throttle stick lock with the StudioX software and the optional
USB2SYS (SPMA3030 or BTXA76007) interface.
For safety reason you should never take off or land with activated SAFE
As SAFE technology actively gives control commands to the control loop of Spektrum
®
AR7210BX, the swashplate may tilt to one side if the helicopter is not placed perfectly
level on the ground. This may cause the helicopter to tilt and crash when trying to take off
or when the motor is switched off and the main rotor is running out.
Fine Tuning SAFE® Technology
The amount of deflection of the SAFE
technology gain. This determines the speed and roughness of the control input from SAFE
technology. If the effect of SAFE
position too slowly, increase the SAFE
SAFE technology channel (i.e. by using the servo throw adjustment for this channel in the
®
transmitter). If, on the other hand, the heli overshoots after reaching neutral position and bobs
briefly, the SAFE
®
that cyclic gain (dial1) and cyclic feed forward (dial 2) are well adjusted. It is recommended to
adapt the SAFE technology gain to the preferred application. If you would like to use SAFE
®
technology as emergency rescue then set the gain as high as possible. On the other hand when
using SAFE technology mainly as a training aid, for example in 3D — mode, then make the
®
effect of SAFE technology rather weak, so that the system does take over control gently.
