Yes. I have seen Raptor 50's flown without a problem with Hitec HS 425's and Futaba 3004's. The 821 I saw fail was on a friends helicopter. He wasn't 3d'ing the Heli just some loops and rolls. It was a problem with the electronics not being able to stand up to the vibs. The Servo's had just hit the market and was recommended by the LHS. He replaced them all with Futaba 9252's.
Here is what Horizon says about it.

The DS821 servo is a powerful, accurate sport digital servo recommended for RC airplane applications up to 1.20-size. For helicopters, the DS821 operates best with 30-size glow models, and up to 50-size electric. Loads and vibration in larger models may cause premature failure of the servo resulting in damage or injury to property and persons. |
