Futaba HPS-A701 Brushless S.Bus2 Programmable Digital Airplane Servo (High Voltage)

I put these on cyclic on my sab 700 raw. I know they say they are for airplanes I liked them because they are lo pro and weigh less than other servos. I have done this with bk brushless low pro servos on other helis with excellent results. Well my elevator servo got physically jammed and smoked for a few seconds before i was able to respond. I removed that servo and found it still worked on my tester (way slower and three times the amps) but it was extremely hard to move by hand. I checked the other two cyclics and the passenger had the same hard to turn problem. I decided to go with a different brand sadly because i am a Futaba lover.
