1. No Pulse
Modern speed controls (ESCs) go automatically to OFF if no control pulses are
available. This important safety feature can be used to achieve failsafe behavior if
on loss of signal the receiver cuts off pulses to the ESC and other channels. This
results in the motor shutting down and the servos not moving.
An advantage of this approach is that it does not rely on the operator to ensure
that the throttle stick is at low position when binding. However, it is not suitable
for use with a model powered by an internal combustion engine (glow or
gasoline), or with an ESC that lacks auto off.
This type of failsafe is used by the Hyperion 7-channel stabilizer.
No Pulse Failsafe is the default for the 6-channel DSMX-compatible, 7-channel
Telemetry enabled DSMX-compatible PPM receiver, 8 and 10 channel DSM2-
compatible and DSMX-compatible receivers, and 8-channel PPM receivers (both
the current DSMX-compatible version and the earlier DSM2-compatible unit).
2. User-Defined Failsafe
This type of failsafe allows the operator, after binding the receiver, to set the
desired failsafe positions of all channels. This allows for such special failsafe
requirements as having a glider go into a spiral with spoilers deployed in order
to prevent a flyaway. Likewise, multicopters may have a failsafe command to
return home using GPS.
User-Defined Failsafe, also known as Pre-set Failsafe, is a user set option on the
6 channel DSMX compatible, 7-channel Telemetry enabled DSMX compatible
PPM receiver, and 8 and10 channel receivers, including the PPM units.
As explained above, the default for these receivers is No Pulse Failsafe.
Setting User-Defined Failsafe. Where user-defined failsafe is available, the
receiver can be set to use it as follows:
1. Power up the transmitter and receiver (which should already be bound).
Do NOT have the transmitter in bind mode.
2. Apply the bind plug to the receiver bind pins (with power on).
3. Set the transmitter controls to the desired failsafe positions.
4. Press in the failsafe switch on the receiver briefly.
5. The Green LED on the receiver will turn on to indicate that failsafe
positions have been stored. Henceforth, whenever the receiver is powered up, the green
LED will indicate “user-defined failsafe”. If signal is lost, the receiver will output the pre-set
positions after approximately 3 seconds and maintain them until a valid signal is
again received. Test the failsafe settings by turning off the transmitter, after taking all
necessary precautions, such as removing propellers or restraining the model.
To return to the default no-pulse failsafe with these receivers, simply rebind the
receiver normally.
