from what i've been hearing it is, on the flip side, you have a great company and a great warranty backing you with those servos, so if the 7940 does turn out to be a dudd(I just bought two of them, so hopefully not) you can send it back for a new one, I've got a couple weeks of racing ahead with them in my cars for throttle, I'll report back, If I dont like them, Its back to the bls451 for me
