I could save an additional 2.16ozs by using standard ball bearing servos. Just not sure they would be up to the task torque wise. Was planning on using Futaba S9405 on rudder, S9001 on elevators and ailerons, and a S3101 micro precision on throttle. Any thoughts, real world experience on servo selection for this plane? Is saving 2.16ozs worth the loss of servo torque and precission of the coreless servos?
