Campgems, I can agree with you to a certain extent. But when it comes to a receiver that is questionable, I have to just replaced it. I don't want to mess around with "maybes". Sure if a piece of electronics have been working fine for 90 days, it probably will be fine down the line. But after a crash, if its questionable, the cost of replacement versus repair, I'm going to replace it. All engineers are familiar with the term "(dog feces) can it" to keep this forum clean of bad words. When it's garbage, it's garbage. So fine, if you want to chance your plane to repaired electronics and feel fine with that, then great. At a certain point, I'd rather just replace it. We agree that we disagree.
