It's not fair to say that they are junk, the problem is they were designed for some other job. That's like saying that a small car is junk because it was crushed when an elephant sat on it. IT wasn't designed for that job.

I don't remember it saying anywhere on the case not to use in a gas engined airplane. At least when I got them they didn't,don't know if they do now. If so then thats a different story. I didn't think using them as a choke servo would be a problem, I was wrong.
