HS-65MG question (concern?)
i recently bougt 16 of these little jewels and i am extremely impressed with them. i use a Futaba 12Z radio and am also impressed that when i power up my 608fs Rx, that the 65's don't even flinch unlike Futaba analogs that deflect a good amount and then return to center.......drives me nuts, but alas, Hitec servos are the answer.
now my concern is gear play (slop)..................i have 2 of 3 planes setup so far with the 65's and there are 2 of these servos that exhibit a slight amount of play in the gears. you can see it when you grab the servo arm and put a slight amount of rotation (but not actually moving the gears) in which the aileron (on one) and the elevator will deflect up or down just under a 1/16"......................this is with power off. with power on, the servos maintain center extremely well.
is this a normal feature of the 65MG's?
or is this something i should be concerned about.
the other 6 servos i have installed at this time are tight as a drum.

Metal geares do have a bit more play than a nylon geared servo so it is normal to a certain point. Over time they will get a bit looser as the metal surfaces wear but you should get many, many flights out of then before the gears would need to be replaced. 
Sometimes you can also rotate the center gear 180* to tighten the servo back up as well.

i understand that they will wear and get a bit loose as they are subjected to use in my models.
my concern is that these are new, and i'd like to know what is within tolerance.
i'd be glad to buy more and keep these as backups.

Some servos will come tighter than others from the factory. Basically, the gears are not exactly 100% round and sometimes you end up with a couple gears that have their low spots lining up. You can rotate the gears in relation to each other which may aleviate the this. Personally, I wouldn't worry about it.
Also use as short of an output arm as possible while using all the radio EPA and dual rate to get the throw you need which will help mechanically so the slop does not affect the surface as much. This also helps with centering and resolution.
