Went out to play today and had that day i wasnt looking forward to.The truck ran smooth for bout 15 min then i noticed all my servos just setting there twitchin and not respondin to my radio.Changed batteries thinkin that was it.Started it back up after it checked out ok servos not twitchin and work with radio.Only owned it few months and knew i needed a failsafe im not cheap just havent had the cash Well off it went full bore 5 feet away radio not workin smack right into my truck tire.My ? is what is makin my servos just set and Twitch and not respond to the radio even setting on workstand and it even stops when radio is shut on and starts back when turned on.Oh and yes i do know i need a failsafe .I learned a costly lesson but atleast im still learnin.
