Has anyone used the newly released Hitec HS-635HB servos yet? I've got 7 on one airplane and was wondering if I should expect any suprises? Let me know the good, the bad and the ugly regarding these servos. Thanks.....

O.S. Master

Hey, I also have bought 635HB's on my U Can Do and their is no problem with them.
They are fabulous servos for a reasonable price.

They are fast, strong, and have surprisingly good centering just like the 5475. Considering its predecessor 605 has really lousy centering, the 635 is a pleasant surprise, especially for the same cost.
