Gsheperd...Yep...just the 40. Seems like most of the flyers here are devoted to 3D flight, and if your plane won't 'hover at 1/2 throttle' you are underpowered. Well, I have seen the SE fly with the added drag and weight of floats (20 oz. + drag) powered by a couple different 46 2 strokers (OS FX and TT Pro). Flies great. It's a terrific platform, but be honest with yourself when you buy the powerplant...Good Luck All.
