Would it be ok to get the standard jr servos 537 40.3 oz on a 4.8 battery. I might get those and a 6v bat. How did you get only on servo for the flaps?
Be aware, that a 6v pack will give you more torque, but lasts only 2/3 as long for flight time between charges. One of the unfair consequences of life.
I use Hi-Tec HS-605 servos (77 oz) for my rudders where a beefier servo than a Futaba S3004 is called for. Of course, they were just discontinued.
