What to do. what to do. Buy another servo I guess.

+1 on the heat. I had a trinity motor a while back that when the motor came to temp it became really notchy and was creating havoc with servos. Not really sure why but my nova's dont have that issue.
I can only point out the usuals - grind down center diff housing to straighten carb angle, grind down chassis guard to clear the servo, make sure the servo is off the chassis, use the rubber grommets, and make sure there is no flex in the servo tray on either way of operation.
Since then I haven't had any problems in both buggy and truggy using 7955 and even a 985 for almost a year.

Hey Marc. Thanks for the input. The 7940 failed but so did 3 7955s in the past 4 weeks.

Hmmm. That's odd. I run the std diff mount, have my carb at slight angle and dont have problems. Something is really funky if you killed 3 7955's. Usually those are pretty stout. Now you have my interest piqued. I'll be there early, I'd like to help you fix this.

Just talked to Hitec. The last servo that I sent in, the problem was "bad IC". The tech told me that "bad IC" happens when the bottom of the servo hits the chassis.
I think that if I case a jump (the chassis is already bowed in the center by just 1/32 and over a year old), it may be flexing enough to hit the bottom of the servo. I cased a jump intentionally last night following a fellow racer because I was coming up on him too fast and didn't want to hit him in the turn after the jump. The servo went out right after.
Maybe it's time for a new chassis? What do you all think?

I'll bring it with me. Should only take 15 min or so to swap out the chassis.

Dave ,a chassis wouldnt hurt sense your really close to needing one anyways. Split diff mount too. I mean the more bases covered the better at this point.
By the looks of it last night your linkage couldn't be set up more perfect.

If you don't want to buy a new one yet, I have one with low runtime on it. You can have it, as I'm not sure that you want to keep running a tweaked chassis. Even if you space the servo up, if you have the bend started, any rough landing will keep bending it.
I'll bring it with me. Should only take 15 min or so to swap out the chassis.
