Hitec HS-5665MH High Voltage Metal Gear High-Speed Digital Servo
For the price, this is the best servo (IMO) you can buy, especially if you are looking for a digital servo that is 7.4v compatible! I use this servo in my Team Associated B5M, and so far it works great! I run by ESC BEC (Tekin RS Gen2) at 7.4 volts and the servo is super smooth, responsive, and it has great holding/steering torque.
