Yes, reverse the process.
- Get the flaps all the way up, and left side same as right side.
- Align the aileron trailing edge with the flap trailing edge.
- Verify the ailerons are hung the same (up, down, in, out) not just the same trailing edge height.
- Now fix the wing tip to match the aileron trailing edge.
Side note - I recommend builders defer the wing tip until aileron and flap rigging complete - and verified with another set of eyes.
