I also agree with the MIDWEST AEROBAT, I have 2, one with an OS52 ( tail dragger ) and one with a Sato 56 ( Trike ) my first had an OS 46 till my wife got the 52 for me. I fly the CRAP out of them and also teach on them. They probably go togeather better and easier then most as they use the MIDWEST manual which is really hard to beat. You can see them at www.falcon-trading.com and also see a review on www.masportaviator.com. ENJOY !!! RED
