Well the title says it all. I have a Revo 3.3 (#5309). After burning 3 Traxxas throttle servos due to the stiff spring found on these revos, I finally decided to get an HS-645MG. Installed it yesterday and noticed something very unusual. We all know how strong the throttle return spring on this model is, but even that failed to pull the throttle back to neutral when I checked the setup.
How I checked? Ok, so I switched on the tx and rx (obviously ), pulled the trigger to Wide open throttle and then switched off the receiver/rx. As per the design and even technically, the return spring is supposed to pull the servo back to neutral to prevent a runaway. But the servo is so hard to turn that even such a stiff spring couldn't bring it back.
Does anyone else have a similar experience or can suggest something, please help. I don't want to take any chances, just in case!
