Neil,
one basic requirement for any safety equipement to work properly is that it is used the correct way.
So when you write : "an arm disarm device would have not prevented the loss from happening . Here is what happened-immediately after landing I grabbed the airplane by the vertical fin to bring it to the pits as at our
field taxing from the runway thru the flightline to the pits is not permitted."
In this case it is obvious that an arming/disarming device would indeed have saved you your plane.
Used correctly, it would have read: Here is what happened-immediately after landing I DISARMED THE BATTERY, grabbed the airplane by the vertical fin and brought the plane back to the pits.
No drama whatsoever.
I also found this one a bit strange: "A plane can still get away with an arm/disarm device."
Please share your secret.
Regards,
Magne
Its all in the name off disiplin(dont know if this is correct english)
I always plug the battery when I change it put the canopy on and leave the plane waiting for next flight , when its my turn It take the plane to the runway turn on the radio check that all run correctly , arm the battery , make the flight land get the plane to me DISARM the battery and turn off the radio(failsafe is some off the first thing I program when I set up a new plane and have checked it)...roll the plane into the pit ..grab a new battery change ..carry the used one to the car ..this so I dont take a used one in a mistake.
one thing I maybe should do more is to check the batteries with a simpel messuring device..I do that in comp but not wihle practice.
I think the arming an important safty device and the jeti anti spark is wery good its no visible spark only I'm a bit concern about the male plug but it should be easy to change that if it get sloppy.
