In general, I see no problem with using crashed electrical components, BUT if its a new and nice (valuable) craft i'll go for new servos,crystals and reciver.
im actually building a tf P51 D 1:7, and am going to get a whole new setup for this craft.
I am doing the same on my turbine jet even though I have plenty of good components. Although I will still thoroughly test the new components, I hear of too many new digital servos failing on a maiden flight!
