Now... pull plane into a inside loop. If the plane wants to turn in or out while doing this. One of two things are causing this. Either the rudder or elevator halves are not properly trimmed (set) to work with each other.(Just because your pitch gage tells you your elevators halves are aligned side to side one the ground.... does not mean they are in the air.) If the plane wants to turn out to the left, add left rudder trim. If the plane want to turn out to the right, add right trim. Correct as necessary so plane will track straight through out a inside loop. IF the plane does not turn out either way... with very little to no rudder input correction... you are ready for the next step.

Now... perform a outside loop once the above has been corrected. If the plane plane wants to turn out right or left, then the elevator halves are not aligned. In the event of turning out to the left, the left elevator is to low. If it turns out to the right, the right elevator half is to low.
