The Jupiter and the Ready from Falcon Trading also do Great flat spins, both upright and inverted. The neat thing about both of these is that all you have to do is let go of the sticks and they right themselves pretty much ( with enough altitude ) something a lot of planes won't do even when forced. They are both 40 size ( I use 46's ) and really fly great no mater what you do with them. You can see them at www falcon-trading.com. ENJOY !!! RED
