What HV savox servo is recommended for throttle and steering on nitro buggy also what protek servo is recommended I'm thinking the 170 are they HV ? Thanks for any reply

I really like the Sanwa ERS-962 which is HV and very high torque. I've had a couple of protek servos in the past and both died very quickly and we're returned under warranty. I used the store credit and bought more Sanwa's! Personally I wouldn't buy any more proteks.
