Has anybody used the TroyBuilt HD 2550A servos? and how are they performing for you?

The first one on the page looks OK. You should buy a bunch and fly'em, let us know how they hold up. Remember, You get what you pay for.

Just buy some Hitec HS5645's and you know you are safe. I would not trust a large investment to some new made in China servo's. That just my opinion.[X(]

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

I ordered the same deal put them in a 15lb gasser, I only wish I would have got more during the promo. Hitec who!!!!!!!!!!!!!!!!!!! Whats Hitec. Just kidding before I offend anyone but great servo.

I took one apart: (1)motor is twice the size of a typical servo (2)pot is connected to circuit board by a connector instead of solder (3)motor has a leaded part (guessing a cap) soldered across its terminal (4)the leads of the cap get soldered to the board (5)leads have braided sleeve to insulate them (6)servo amplifier appears to be their own design (7)two large transistors are used to drive the motor (8)all gears are metal including motor pinion (9)gears are well lubed (10)grease appears to have already collected metallic particles with a few cycles back and forth (11)motor appears to be press fit with no screws used (12)wires are awfully small gage about what you'd find on a park flyer servo (13)wires exit without a restrained grommet (14)no staking adhesive used on wires.

Performance wise, servo is extremely powerful. I can't stall it with my fingers. Holding the arm before moving the servo is the only way I can stall it. The metallic particles I found in the grease appear to indicate very fast wear on the gears. Servo is very very quiet at idle. Centers very well with no oscillation. A little more backlash than say a ST125. Speed is comparable to most analog servos.

Look like the pros and cons are going to be about the same.I really dont like the small wires,that could be a problem.Think i'll just sit on it for awhile and see if we get any other reports.some things i like and some i dont. Thanks for your oppinions.
