Okay so I'm fairly new to the nitro scene, but anyway, I have a thunder tiger eb4 s2 pro, but the throttle and steering servos seem to be twitching the whole time, and when I press the throttle it just opens and then shuts again quickly, and the steering just slowly twitches when I turn the wheel, any help would be appreciated thanks.

Are you running AM or FM radio gear or 2.4ghz? Do you have a fail safe installed? Is your receiver battery pack fully charged?

Try charging your batteries.

Your reciever pack needs charging or your alkaline batteries are dead

Which ever one powers your servos
