I did have to add more right thrust than what was built into the airframe. But you have to remember that even changing your prop can change the thrust amount needed to hold a straight upline. You must use the same prop you trimmed your plane with when flying sequences. This is why so many pilots are falling in love with Mejlick props for there 50cc-150cc planes. You can use the same prop for sequences and 3D, they have a nice balance of both worlds without swapping back and forth.
