[LASS Soaring] bad crystal?

[Dion Dunn]

I went out flying today (well, I tried anyway) only to be grounded by a
really glitchy radio.  I tried changing batteries, removing and replacing
the servo leads, removing and turning the crystal around, everything.  So
no, I did not actually get any flying in.

 

When I got home, I tried another receiver and it worked fine.  Hoping the
receiver in the plane isn't bad, I replaced the crystal with a new one, and
it worked perfectly.  Here is the possible cause: a few weeks ago out at the
field, on my last flight of the day the rudder servo decides to strip its
gears in flight during final approach.  Result - the Sagitta went nose first
into one of the big pine trees and slid down to the ground.  No apparent
damage, but it was a good smack at the bottom.  The receiver was wrapped in
foam, so I didn't think anything about it.  I got home, replaced the servo
gears with new metal gears, tested out the radio and servo and everything
was working fine.  Fast forward 2 weeks to today, and the crystal is bad.
How does that happen?
