Elevator problems
 

Let me start off with what I have.
heli: Walkera 450d03
radio: Walkera devo8s

now the problem: Frist I am a newbie.

I recently had a crash and bent the tail boom, broke the main blades ,the large gear thanks to a small tree. Replaced all the parts leveled the swash plate balanced the blades, everything seems to be right the problem is when I fire up the heli and get it up to about 50% throttle and run a check on the rudder its ok, but when I push up on the elevator instead of the heli leaning forward like it's supposed to. If looking from the rear the heli wants to lean forward and to the left but more left then forward. I know with not being able view it in person it would be hard to diagnose the problem but any thoughts would help. Thanks
