My small hitec servo failed on the boost tab and that is all I had powering my big elevators!
That will do it,
the reason for not going too small on servos, is not for the flight loads but rather because of vibrations, also if you do go small on the servo, make sure you mass balance the control surface properly.
On my 34% Turbo prop laser, I am using only one 75 oz. nylon gear servo per control surface. Two years now.
