First of all, I want to say that it is refreshing to see that so many people are willing to take responsibility for their own actions. I have zero respect for the losers who think that everything that happens to them is somebody elses fault. But you know, sometimes it actually is somebody elses fault.

Given the facts as stated, that he installed the servo exactly as described in the instructions and there turned out to be insufficient structure under the surface to hold it, this case is the same as you purchasing a new car and the first time you go to fill the tank, the gas all goes all over the place and catches fire because there was no tube installed between the gas filler and the tank.

I'm sure cstevec always takes the time to peer inside the gas filler to make sure there is a tube in there before filling up, (what if the tube isn't connected to the tank?) but the rest of us pretty much rely on the manufacturer to do his part right.

And that's the law as well. The manufacturer (and the seller) is legally responsible for what the factory did, and the kit/ARF assembler is legally responsible for what he did. It's common sense, and for once the law agrees.

Here's something you might want to think about: If you alter or "improve" the manufacturers product in any way, you legally relieve him of any responsibility if your changes can be even remotely related to a later failure.
