You got that right. Years ago I got an airtronics servo on the advice of the hobby shop. The first few races it did just fine but then I started having a centering issue with it. I went through the car and found one ball end that was just a bit tight. The servo had so little torque that that was all it took to screw it up. Replaced that ball end and all was fine for one more race before it completely died. Slapped a 9650 in it and never had another issue. Had I been a noob, I probably would have slapped the whole rig on ebay and given up in frustration.
