Add Voltage Failsafe to Spektrum Surface Receivers with Dynamite Race Guard
Spektrum Surface Failsafe Tips
Spektrum surface radios include a signal loss failsafe, but they do not have a voltage failsafe. To allow this feature, RC Racers can use an aftermarket failsafe such as the Dynamite Race Guard Micro Fail Safe, Dynamite RC Part DYN2553, to build in a voltage failsafe. The Race Guard will kick in when the voltage drops below 4.0 volts.
- Plug your power switch lead or ESC lead into the Spektrum receiver. Press and hold the bind button on the receiver and power it up. This will put it into the binding mode which should be indicated by a rapidly flashing green light on the receiver.
- Press the throttle trigger to the desired failsafe position and hold it. This is usually a full brake position. While holding the failsafe setting, press the clear button on the back of the transmitter and hold it down while turning on the transmitter. When the light on the receiver goes out, let go of everything.
- Now that the transmitter and receiver are bound together, you can power everything off. Plug the Race Guard into the throttle channel on the receiver and then plug the throttle servo into the other end of the Race Guard.
- Power everything back on again. While holding the transmitter in a full brake setting, you need to press the Setup button on the Race Guard Failsafe. The light should then change to orange. Release the setup button and the light should turn back to green.
- Now, everything should be setup. To test the function of the loss of signal failsafe, turn off your transmitter while the receiver is powered up. You should notice your throttle servo goes to a full brake position. To test the function of your voltage failsafe, let the battery pack draw lower than 4 volts, at which point you should see it go into failsafe mode and then the light on the Race Guard will change to a solid red color.
