i personally think a Kougar would be a good plane to have. the only drawback to it is that it is a kit not ARF. it flys great and dotn have any bad habbits. if you can find one used i would jump on it. i dont know how that four stroke would pull it but i have an OS .46 ax with 11x7 apc prop with tuned pipe and has all kinds of power. unlimited verticle. i think i should put 1 size bigger pitch to try to get a little more speed out of it so it will knife edge better but other wise this is a great plane to have. it glides forever. so you dont have to be good at dead sticks it lands like a dream.
