May be I have lost the plot, but I just don't get WHY so many of you guys continue to use marginal servos when, with just a few extra dollars/ pounds you could use a servo that is more than powerful/suitable enough to meet the requirements of the aircraft in question. Time and time and time again, I hear of servos suffering from control surface flutter, being unable to cope with jet speeds etc and yet perfectly good, powerful servos with metal gears are readily available at little extra cost . I got it in the neck from some of the BVM police when I questioned the original Bobcat servo spec., (its the ONLY thing Bob got wrong on this otherwise superb machine) they had to eat their words when 3301s and 3421s proved, in some cases, as I had predicted, to be inadequate and failed.

Funny thing is, I have yet to hear of ANYONE reporting the loss of a jet model because the servos were too powerful for the control surface. If there is ANY doubt about the power/suitability of the servo, there is NO doubt, use a more powerful one, hardly rocket science !

Merry christmas !
