Yep, I too run the Hextronic 5010's in all my 40/60 sized birds. They cost me $4.50 each from china and one set of 5 have over 250 flights on them!!!! They work prefectly. Never had an issue on any of the 12 I have. Some of the more expensive servos have slightly better resolution, but for the money they'll work fine. There's 0 slop and they center perfectly every time. They run perfectly on 6.6V a123 power as well, and put out a pile of torque.
