Hey Scott your going to love the Magic. It's a total blast to fly! I would recomemd you use the 46 on it. Watch your balance and make sure you static balance it carefully. As you are harrier landing and slow flying the need to do this is extremly critical. You don't need anything more than standard servos. One thing the plane does bad is knife edge but it will thrill you in so many other ways. Good luck with yours.
