RE: DIGITAL SERVOS?
I think there is a misconception about torque with digitals
Digitals are not more powerfull because they are digitals. If you take the same servo, one with a digital amp inside and one with an analogue amp, the torque will be the same.
But the one with the digital amp with have more torque from the starting point and will have more holding power.
It will be a bit more precise, but again not necessarily so. If you have a digital with a 3 pole motor, it will not be very precise,but a digital with a 5 pole motor or a coreless will be much more precise just like with the analogues.
Don't forget, Pattern flyers were flying very precise maneuvers back in the 70's with AM radios, and analogue servos which weren't even as good as the Futaba 148's..
I love the digitals and wouldn't go back to analogue unless its an insignificant airplane, but not because I MUST have be rather because I simply want it.
