OK - I flown both the katana and the mojo and loved the mojo and like the kat. My mojo as you read died and I have since ordered a kit and an ARF. The ARF will get together first and the kit will take a bit when I have spare time. I feel the mojo to be the better of the 2 by a decent margin. My katana will not do a normal harrier at all. To get it to sorta harrier it needs to be at a 65-70 degree angle and that makes it more of a hover than anything else. My mojo would harrier around at prtty much any angle and didn't care. For general flying they both are as good as anything with a fun-fly type wing. The mojo has a 2" shorter wing span I think and there for fits in my car better than the kat.

The mojo is in my mind the top 3D profile in the forty class HANDS DOWN !!!!!!!
