I like the Hangar 9 Twist. It comes in a .40 or .60 size and is very aerobatic. The plane will do all the basic aerobatis like loops, rolls, knife edges, flat spins, rolling circles and is also very easy to hover. My 40 size Twist is outfitted with an OS .46 AX spinning an 11 x 6. I have experimented with many props combinations but the 11 x 6 is my favorite. the Twist was one of my first aerobatic planes from about two years ago and I still fly it regularly.
