servos for 2M
no problem in my opinion, only thing is the weights of the servos in the stab. May or may not make a tail heavy model.
I have 9202's on my ailerons in the 2M Titan, and they are great.
The 9101's I have used in the past were just as good.
1 per elevator half will be strong enough for the lower AMA schedules. Now from advanced up, I might would consider a stronger servo for the snaps and such.
Sure, their not digitals, but they are not $100 per servo either.
There are lighter and more accurate alternatives, but if you have them, and like them, then use them.
