It's really very easy to choose a prop for one of these things. Just give DA a call, tell them the type of performance you want from the airplane, and I can guarantee you they will tell you what prop and brand will gibe it to you. Best bets are a 22x10 or 24x8 Menz or Mejzlik for the the two blades. On those props I can promise you that you won't have performance worries. In fact, it'll probably take 3-5 weekends of hard flying just to get to the point where you will be able to control it without using too much power. They don't guess on props, they test them. They will tell you exactly how each one performs. Hope this helps.
