I had one before and its rudder broke and wouldn't respond, so i couldn't steer the plane, so i got a new one today and the exact same thing has happened when i haven't even crashed it, the rudder just won't move/respond when i want it to its just dead. Anyone know how to fix it? Twice in a row now :'(

Do you mean the servo moving it wont respond or it will and it makes noise but wont turn it?
If the servo just isn't responding just try making sure its plugged in all the way. If still nothing then that is a receiver problem or a servo problem.

If it makes noise but there is no movement, it Probably stripped the servo gear. This is the most likely case, just buy a new one or get one with metal servo gearsso it doesn't happen again.
