I have the 1.20 Lanier Edge 540. I love the way it flies but my webra has seen its better day. I cant wait to order an O.S. 1.60 and finally change the servos that were in it when I bought it. The guy had standards on the elevator and a goodish (Hitech 605BB) on the rudder. I figure I will slide the 605 to the elevator and purchase another one, and I will do away with the rudder servo by putting a good servo on there. Before the engine died on me (4 months ago) I managed to get 30 or so flights on it and I was impressed. The linkage to the elevator was only giving me around 25 degrees deflection. Even with the small throws I did manage to do some flat spins, and a good looking blender. The 1.20 webra would hover the plane but it was done at 4/5 throttle so I never felt safe about bringing it on down below 50 ft. As far as IMAC goes: I have just started practicing IMAC ( I plan to start competing next year) I flew the sportsman sequence with it a few times and it really seemed to do well. Vert. lines were very straight and rolls were crisp and clean.
