[FTC]: dual synchronized servos or geared up winch servo?
The kids have ball dumper that is controlled by a quarter-scale HS-785HB servo. Apparently the dumper is a little heavy, as the spline on the servo stripped (it may have not been properly seated, which may have contributed).

With a competition coming up this weekend and the girls also on an FRC team, there isn't time for a full redesign of something that was working pretty well. There seems to be two options we've discussed that might work:

(1) buy two HS-755HB servos, put them on opposite sides of the ball dumper, and synchronize them.

(2) buy a HS-785HB winch servo (3.5 rotations) and gear it up.


On #1, we are afraid that if they don't sync perfectly there will be problems (they may fight each other).

On #2, we are afraid of gear slippage because it need some amount of precision.

Anyone have experience with either option? Or other thoughts? Thanks!
