Did you use same kind of servo's for both elevator and rudder?If not some of them have a greater voltage stability while the others don't. Otherwise, the only suspection  is a 'short' in the circuit board.

It's clear from above that it's overvoltage problem. Keeping the voltage below 5.5V can ensure a good stability and avoid burns for small analog servo's.

If all else for eg voltage is ok, just don't use avionic crap.
A friend's servos on brand new stealth got screwed mid flight in maiden.
All groun tests were ok.
Servos simply failed.
