On my first flight of the day my high speed needle valve assembly got loose inflight and fell off, which resulted into a low but high speed forced auto. I was able to find the needle valve in the grass thanks to some great friends and a small search party and was able to fly again after alittle lock-tite.

my hz-ps was a pain for that, had 1 fall off just as i landed because it was going lean.
blew up an sz-ps due to same issue
have had it happen 4 times on 3 motors.

did you use lock tite on any of them to resolve the issue? just currious cause I put some blue lock tite and I know that it melts off to heat but this part of the motor doesn't recieve much heat at all. IMO.

not i just tightened it up tight with a socket, only had 1 issue doing it that way and thats because i did not do it tight enough, only came slightly lose that time but still counted. always check mine just by trying to wiggle the reg to see if its come lose.

at least no futher damage was done with yours.
