I have an Evo 46 in my PNP 80" H9 Cub. It flys it great. It will haul it around good at 2/3 throttle. You can even do huge loops with the engine. Take off is this engnines only down fall. Its not enough to horse it into the air on a short take off. As long as you have a good 70 feet you will lift off just fine. If you get in a hurry and try to get it in the air, you will be sanding and covering for a few days, and trust me I know from experience. You cant get a new windshield until August, and the metal wing tubes are not for sale yet either. This is a great looking Cub and flys really sweet. Mine does not look so great after the tip stall, but after I get a little more practice with it, I will buy another.
