[NSRCA-discussion] Pletty CC HV 85 issue

[Stuart Chale]

No not a change in throttle input.  I remember clearly that the second 
time it happened that I wasn't really pushing it.  I agree that 
something must be going bad somewhere.  I have an extra CC HV85 that I 
an going to swap in tomorrow.  On the other hand I had an almost similar 
situation in Justin's (my son's) Angel 50 but the problem was 
reproducible with full throttle even on the ground.  Turned out that 
that was the motor (extreme flight).  I had a second setup both motor 
and ESC and swapped one piece then the other.

Thanks,
Stuart
