Saw a 110 Rascal fly a couple of weeks ago in Bowling Green. He has a Saito 180 with a custom exhaust. You would have thought this thing was an aerobat instead of a big trainer. knife edge, loops and that good pilot stuff plus he would hover it about 20 feet off the deck and then go straigh up with unlimited vertical, and besides all of that it had that terrific 4- stroke sound
