Re: Engineering Failure Analysis

I have seen that servos can occasionally twitch with large random movements when the RC changes states or when it is reset. I've observed the random "twitches" to get worse or better depending on the master code that happens to be loaded and which PWM output is used. Victors controlling motors haven't suffered from a similar twitch since IFI fixed that part of the problem with Master Code v11.

Having the value already set to 255 during initialization then resetting it to the identical value later to solve your problem certainly is puzzling though. It'd be interesting to check the value just before the reset to see if it is occasionally not what it should be. (Makes me want to go play...)
