Comments: Very good servo for beginners or those on a budget.
Not recommended for 3d.
But it can handle a beating.
Have had 100 + flights with these servos in my caliber 3.
work great for alerons, elevator, throttle, lacking in power for pitch in mech mixing. But they're holding up good.
Have carbonite gears as other high quality servos.
