Just got my batch of 10 servos (paid for five, five free, TBM)....servo leads seem pretty thin gauge wire compared to the Hitec servo's I have, servo arms appear cheap. Mounting screws were 3/16 long compared to Hitec's 5/16. I don't trust the mounting screws to be long enough to hold the servo in place. The servo arms go in the trash and I'll use Dubro HD arms........anyway, I'll test them in a 60 size U CAN DO before I commit them to something bigger. Now to find new mounting screws. I don't think TBM would promote this servo if it did not live up to their standards. We'll see..................Henry
