There are literally thousands of R149DP receivers in service in North America, let alone in the rest of the world. There were 4 or 5 events reported in that thread. While some people may have had a problem, it's usually not possible to determine if a component failure happened prior to or as a result of a crash.

We sincerely doubt that the one person's club had a dozen or so R149DF receivers fail out of the blue. Usually receiver failures can be traced to a bad installation, or a prior crash where nothing "happened" to it. We have never received a large number of returns for repair from any one area. If a large number of people in the same area are having problems, and other places are not, we'd start to wonder what they are all doing that is common to all the receivers.

One thing to be aware of is that many, many modelers just aren't installing their receivers particularly well. The receiver should be wrapped in at least 1/2" of foam rubber all around it, and the foam rubber must not be compressed. We've seen installations that used a gel pad, only, between the receiver and airframe, a thin layer of foam and velcro strapping, and even just a bit of double-stick foam tape between the receiver and the airframe. Velcro is fine, but it must not compress the foam, otherwise the purpose of the foam as a vibration-isolator is ruined.
