[NSRCA-discussion] Mezon 90 Lite investigation

[Daniel Underkofler]

I used this Jeti switch and the Mezon 90L and had a dangerous incident that
seems to be related to Andrew's post.
I tend to grap hold of the magnetic key as I approach the plane after a
flight.  I usually unplug the main battery power via the external plug.
This day I instead first applied the magnetic key to turn the Rx off.
Motor came to life (lower power, about 2sec)  Fortunately I didn't have
body parts in the props and grabbed the plane before it rotated into me.  I
did replicate the occurrence, but  only once in several tries.
So, beware! (and more importantly, keep your head out of your ass and
unplug the power first)
