RE: Servo--Rx Breakin ideas please.
I use the Kraft route. Stick the gear in a hack and fly it. I like to be confident in my RC gear so if something untoward happens in the first few flights of a new model I can be reasonably confident that it is not the RC components, maybe the installation but not the gear.
Incidentally in all the years of doing this [30+] I only found a couple of twittery servos and one glitch prone receiver.
