Add weight to the front or reduce weight on the back.

Keep adding weight to the front until it stops doing a wheelie then see if it flies still

@BlueCitrus
still doing a wheelie

@SiYanto Oh! When it's not moving.... well i would try adding weight to the front

@BlueCitrus
the elavators are fine
but it does a wheelie when its not moving

@SiYanto well then either add weight to the front or angle the elevators (horizontal stabilizers) front end down

@BlueCitrus
the problem is when is the plane is balancing on the back wheel

@BlueCitrus
yes

When it takes off, does it pitch upward at all?

@BlueCitrus
the plane does a wheelie

With what? What's the problem?
