Mad. You've had no problems with the 7940 on throttle /brake? I have lost 2 of them on throttle and made damn sure my endpoints were correct. I sent them back and they were nice enough to swap the 7945 gear set which slowed them down some and then I lost 1 of the repaired 7945 in a main and switched back to only 7955 or 7954's in my Truck. I run the KO RXs Power's for both in my buggy (I got them for a song couldn't pass the deal) wow are the a piece of artwork. It could have been bad luck or opperator error.

I believe in buying the most torque and speed you can afford. You can always turn it down if its too fast

The 7940 in my buggy is five years old and has never had a hiccup. I said that last month about the 7950 that was on steering for the same amount of time and it died a week later Hopefully I havent jinxed myself.

I also have one on throttle duty in my truggy not as old and three more on steering duty for my 1/10 2wd buggy, 4wd buggy, and ST. I've had no failures with the 7940s and one 7950 fail. While I can say for sure that your failure(s) were due to user error, I would suspect it. My 1/8s have 7mm venturis and the EPA is adjusted to stop just past the venturi opening (less than a mm). On the brake side, my EPAs are set to ride the line of locking up the tires (typically somewhere between 25-35%). At this moment, throttle EPA is at 60% and brakes are at 30%.

With that being said, EPA is only half the equation. I am very meticulous with the throttle and brake linkage to make sure that the servo isnt fighting the linkage at neutral. Other than that, I really dont know what would cause a failure as it really is a low stress application when everything is setup correctly.

I'm torn between the 7955 and the 7940 for throttle/brake...suggestions?

Can't go wrong with either. They have a new brushless servo that looks pretty impressive too. I plan on migrating to those pretty soon.
