An Important Safety Issue
Submitted by Rex Geivett
I want to point out a potential safety issue with programmable radios.
Most of these radios have what’s called “Fail Safe”. What this means is that if the receiver fails to “see” it’s transmitter signal for more than a
short duration, it will go into Fail Safe mode and position the servos and motor controller to pre-programmed positions. For safety, one would program
this mode for motor power off.
If this mode is inadvertently set to turn power on instead of off, it could cause an unexpected sudden prop spin. This actually happened when an
Easy Star’s controls were being preflight tested on a table. In this case, after the pilot finished his control checks he turned off the transmitter.
The receiver, still powered up, went to Fail Safe mode and “told” the ESC to turn the motor to full on. The result was a badly sliced finger. This
example was an electric motor but glow/gas engine can go from idle to full on also.
A word to the wise: Test to make sure your radio is set for proper Fail Safe mode. Test CAREFULLY by turning off the transmitter while the receiver
and motor are powered to ensure the motor stays/goes off.
Fail Safe mode is programmed differently for various manufacturers, so consult your owner’s manual for procedure if you need to reprogram. Note that
SOME high end ESC’s shut the motor off on signal loss, but many do not, so please do the test.
Properly programmed Fail Safe could prevent an injury, and if your plane goes into Fail Safe while flying, at least it will crash at low speed.
