Ok, so I just got my rc8t running. I put a mamba monster esc in it with a castle 2200 motor and a hitec7955tg servo in it. Running on 4s it started glitching like crazy, so I put a spektrum capacitor in it. Still glitched so we put a castle external bec in it. I raced last night and the first two races I thought I noticed it glitching slightly, the main race it glitched bad. Any suggestions? Maybe a bad receiver? Bad servo? After I put in the external bec is there a setting I needed to adjust in the esc?
