Hubin timer FM9v, external push button with CC edge light 50 esc.

Found this out during ground crew safety drill.

Push the button and get the warning spin for 30 sec count down. Push the button again at 20 sec and motor still starts as normal at 30 sec. Button does not stop the count down. After 30 sec as the motor is running push the button and motor stops. Is this normal?

Any time arming plug is in, hang on to plane which is what saved the day.




Thanks,

On all the timers I use, the only way to really RESET everything is to disconnect the battery (or pull the arming plug)

It's a new switch and it seems to work consistently. Does yours stop the count down?

I have 4 Hubin FM9 timers and they all do the same thing. I don't think you guys are reading the OP.

When I push the button it stops the countdown, it will also stop the motor if it is already running. Maybe your ground crew isn't hitting the button all the way? 4 timers is unusual to have the same issue(but not impossibe). I would check the buttons and if no problems check the ground crew.

O.k,   I misread the part the button was pushed before the start up.   as I just tested it, and it does not stop it from starting.  But any time after the start up it will.   So I assumed it is normal.
