Racers Edge Aluminum Pro Adjustable Double Arm JR Servo Horn (Hard Anodized)
This is a great servo arm, however, based upon my experience, I feel compelled to alert fellow hobbyist regarding the design. The ends of this servo arm do not have enough clearance. Subsequently, the ends of the arm will scrub and bind against the servo. The binding and scrubbing will cause engine and servo malfunctions and failures. To achieve proper clearance, I had to dremel the ends of the arm. Because of that issue, I'm rating this product as "bad", but only to alert others and to maybe get the manufacturers attention, cos' aside from that, this servo arm is superior to other brands and types.)
