Good servo, not so good horns.

These servos are great performers. However the servo horns would not hold up to the torque that these servos put out. Would like to see these servos come with heavy duty horns like the ones that come with many of the HITEC servos.

A standard sized tail servo was tight on my Saxxos DB7.... this was the logical alternative, low profile and strong. The Saxxos still use a drive shaft type tail control, no servo arm, direct drive set up, this servo fit perfectly.
