servo arm selection
Can you offer some advice please. Last night I was flying my midwest super stinker- a 14 pound aerobatic aircraft with two futaba 3152 servos on the elevators. After a snap roll one of the futaba servo arms, supplied with the servo, failed at the hub. Was I unlucky or should I be using an alternatative horn to the one supplied with the servo? I was able to land the plane, after a fashion as one elevator was displace to about 20-30 degrees down from normal. Hence I was able to spot the problem- if the plane had crashed I would not have been able to determine the cause as I would have assumed the arm had been damaged in the crash..
