Regardless of what you get, you have to build a Pqhor. You will not believe how much your flying will progress. Before you know it you will be tail touching while torque rolling!! You can build one for any engine from a .25 on up. A .91 is the biggest I've seen so far. A guy at my field built a pretty big one and is going to use a 1.08 or a 1.20 two stroke. If I bust up my Katana I will probably try to build one for my Saito 1.80!!
