Compared to the ones you have listed, AsM, the Flip is second best. From what i have heard the new madness 2 is better (but i havn't tried it yet). The flip is still better over the madness 1 however! I have flown the Laser 3D and Hype, the laser is now getting dated and you have to build it, there are also things it wont do, the hype is good, but i was put off by the slow rolling, also the hype wing dosen't look as good as the flips,( just personal preference!).
Either engine is good the west 50 is great but also look at the YS 63 and OS 50SX engines, they are all about the same, also if you are on a budget the Irvine 53 is good, and the ASP (just engines) 53 is also superb.
I have left my wing tips as they are on the flip, high alpha KE is great and it KE spins into next week. If you cut off the tips i think it will spoil the looks of the plane!
