this plane is a great flier but like the other guy said, hell on wheels. When you go to take off expect it to ground loop if you put on to much power so ease the power on and take your time on take off, on landing you need to almost do a 3 point landing. set your wheels at 0-0 toe to make a better roll. if you toe the wheels in, when one side of the wing lifts it will ground loop on you.. we have 2 of those and we put OS 46 fxs in both with a Pitt's style mufflers out the bottom. Make sure you epoxy the inside of your firewall and change the cowl mount screws to Allen heads with blind nuts. we put our lead weight in the cowl and have about 15 flights each and no problems except of taking off. any other questions just Email me and we will help you out. look at my gallery I think I put the At 6 picture in it,..
