I'm finishing one up with a OS 160FX in it right now. People hover these things with Saito 150-180's. From what I've seen building the plane the airframe will need considerable reinforcement to the front for that motor (probably replace the firewall) and you're gonna have to move something to the tail to balance out that monster on the front. Overall your looking at making a 10-11 lb plane into a 12-14lb one but hey if all your gonna do is sit it in the vertical position and hover it all day you'll be glad you went with that monster otherwise your gonna hurt the plane's general flying performance somewhat.
