Do you e power guys ever worry about bit flip from a stray cosmic ray or alpha particle disturbing your timer or esc while flying?

No more than I used to worry about a stray bee getting sucked into the venturi

A bird strike or broken line is more likely. With me, a fatal (to the plane) pilot error is more likely!

THANKS now I have something ELSE to obsess about.. :o ??? ;) LL~ LL~ LL~

Well, maybe not, most memory has built in error correction for just such a contingency. I just wondered about the escs and controllers where they are so minimal and stripped down...

Don't have a clue (yet), but I did have a "COSMIC RAY GUN" when I was a kid...........
Merry Christmas

Don't point that thing at my plane when I'm flying !!!
Seriously, the chances of a "bit flip" problem are small -- microprocessors and other integrated circuits are designed to be generally reliable; if they were susceptible to radiation they wouldn't make it out of the prototype stage, at least at a responsible manufacturer. This means that even a "stripped down" bit of kit like an ESC or a timer is going to inherit that general reliability from the parts its made of*. While radiation may be a source of the occasional random error it's not a huge one unless you're flying someplace that's not healthy for you. I think there's enough people flying electric now that if this were a huge problem with reliability in these things we'd know, and we'd still be flying nitro planes exclusively.
* Assuming that the engineers that design the circuits don't screw things up. That's always possible, but that's what product testing is for.
