We installed 775s that did not show any issues right out of the box and after running them for a short while, the short presented itself. I would not feel comfortable with 775s on my robot at all. At any point the short can occur and cause huge potential issues.
We use 2 servos to release our minibot. One to release the deployment system and one to actually launch the minibot. The 775s would cause grounding issues throughout the entire robot because they were directly interfaced to the frame. We tried completely isolating the motor and gearbox from the frame by adding thin electrical tape in between and also switching to plastic screws, but this did not work. The pinion is still directly connected to the frame through the other gears.
When we would run our elevator at full speed it would cause the servos to move around as if they were getting a dirty signal. If we ran our elevator full speed from ground to top peg it would drift the servos enough to release our deployment system. Needless to say this is an extremely frustrating problem.
We are removing the 775s from our robot for Boston. It's simply too big of a risk/headache to continue using them.
Your mileage may vary however.
