RE: Servo Torque and Arm Length....???
The thread started out asking about servo torque------now it has morphed into servo selection which is both mechanical AND subjective.
Torque requirement addresses only the MINIMUM needed -----there is a whole lot more to the choice.
Some (and I mean good flyers) say they see no difference between the base digital and the high dollar variety. I can see AND feel just a whole lot of difference between the two. For my personal use I will pay the price for TIGHT !!
If you don't understand what is meant by 'tight' then you can fly the base line servo----if you do understand 'tight' then high dollar it is.
Frankly, I'll change servos anytime I can get tighter. I'll pay the cost and weight penalty although this isn't too much. Current choice JR 8611-----changed from JR 8411. Yes the 8611 is tighter and smoother but not an enormous amount -----enough though! Torque----well each are overkill @220ozin and 155ozin respectively.
The thread really needs to return to torque measuremant.
