Tuomas,

S9150 and S9154 will accept regulated 6.0 V but not an unregulated 5-cell pack.
I have had this confirmed from Futaba.

Generally I have measured that current consumption will almost double in migration to digitals. Iow. when changing all control surfaces from analog to digital servos and other factors (plane, flying style) remain the same. Increasing voltage will increase current consumption roughly in square.

If a servo gear is too flexible for the application the pots will wear fast as the output shaft and the pot is in constant movement caused by vibration. I can assure you S9150/9154 is very rigid and one of the most heavy duty servos used in F3A pattern and in especially aileron. I can not comment or compare to JR as I do not have any first hand experience on them.


We can discuss this further this weekend ...
