6.13 Configuring Return to Home and other Safety Modes
If you have the optional GPS, the Return to Home feature (RTH), when configured properly, can return your
model to the “home point” if your radio link is lost (in failsafe). Additionally, the MicroVector lets you
program the maximum distance and maximum altitude that your model should never exceed.
Here are the steps to configure Safety Settings:
 Configuring your MicroVector and radio so that the
MicroVector can detect when your radio is in failsafe
 Selecting what you want the model to do when failsafe is
detected (land, return home, return home and land, etc.)
 Setting the Maximum Distance and Maximum Altitude
 Testing RTH to make sure it’s working correctly (described later in the document)
 Making any necessary adjustments to improve RTH (though normally the default settings work well).
See section 7.4 - ‘Return to Home Testing and Operation (GPS Required)’ later in the manual.
6.13.1 Selecting the Failsafe Detection Method
Note: After configuring RTH, make sure you test it as described in section 7.4.2 - ‘RTH Ground Testing’!
For RTH to function, the MicroVector must be able to detect when the receiver is in failsafe mode.
If you are using a Spektrum™ satellite receiver, since the satellite stops sending pulses
when radio link is lost, it is not necessary to configure failsafe detection (the MicroVector
detects this condition automatically).
For non-satellite receivers, the MicroVector can detect failsafe in one of 3 ways, depending
on your receiver’s capabilities. First decide which method you want to use below, and then
tell the MicroVector which method to use by invoking menu mode, navigating to the “Safety Configuration
Menu”, and changing the “Failsafe Detection Method” item as described below. Then, run the Receiver
Analysis Wizard so that the MicroVector can learn about the failsafe settings.
a) S.BUS™ Method: If you are using S.BUS™ mode with your
receiver, the MicroVector can detect failsafe automatically. To
do this, just select the “S.BUS” option for “Failsafe Detection
Method”.
b) Mode Switch Method: If you programmed an “RTH Test”
position on your mode/submode switches, and if your radio
supports it, you can program your radio to force the
mode/submode switches into the positions that trigger RTH
Test when a failsafe occurs. This is the simplest way to set up
failsafe for non S.BUS™ radios.
To do this, program your receiver failsafes as described above,
and select the “Mode Swch” option for “Failsafe Detection
Method”.
c) Throttle Failsafe Method: If you are unable to program a
failsafe on your Mode switch position, or don’t want to use a
mode switch position for RTH, an alternative is to program your
