I bought 5 Hitec servos for a new plane because they were a bit less $$. Before the plane even left the ground, one of the aileron servos started making a buzzing noise and deflected the aileron to the full down position. When I opened the case I found a cold solder joint. I resoldered the joint and it seemed to work ok but it could have cost me a new plane! I pulled the rest of the Hitecs, cut off and saved the wires, and and threw the rest away away! So now I only buy Futabas. I realize that I may have just got an "odd lemon" but I have bought over 4 dozen Futaba servos since then and have never had a problem with any of them! That speaks volumes to me. I won't go for cheaper servos again! [8D]
