Bent nose gear is a common problem on a trainer plane.
One cause is bad landings. As you get more experienced, you'll beat up the gear a lot less.
Another cause is soft wire used to make the gear. You can upgrade with something from Dubro, Fults or similar. It can still be bent from a hard landing but it will be much better than some of the butter-soft wire that comes with some ARF's.
