Javier maybe Pele launches harder than you? Or maybe the mechanical design of your airplane is better? The servo designer probably wonders why the freeflight guys abuse his servos. The servo sales guy doesn't care :-). I have noticed that... the HS 65 can get into a funny state where it draws over an amp. This is more likely if you are driving out side the normal operating range. This could happen if you are right at one end of the range of movement. You may just need a bigger servo. Their digital equivalent may have more power even if it is harder on the battery. Typically digital servos are more sensitive to getting good data from the timer.

The servos do not last forever but the ones you are using are not too bad and even with the amount you fly it seems like a high failure rate. While I can't comment on how M&K's electronics works and if you exclude obvious abuse such as co...nnecting the servos the wrong way around I would check 3 things. (1) Wear, including frayed wires and connectors, R/C connectors can last less than 100 connect/disconnect cycles. (2) Mechanically binding surfaces or using brute servo force to move a surface instead of good mechanical design. (3) Too high a servo voltage or out of spec pulses from the timer. I would think the latter is not likely as M&K would have checked that and the Hitek servos are more sensitive than some other makes and won't work if the pulses are too far out. It is possible that the passive components in the step up circuit have drifted causing a too high a voltage. All of this is probably obvious to a flyer at your level but judging by your comments you do seem to have a higher than average failure rate.
