I don't know what kind of performance you are looking for, but my setup is light weight and probably would have no more than a 1.1:1 thrust to weight ratio. I still have not tested it yet, but it looks like a bigger motor and battery can be used to balance mine out (I'm not sure how different the balance of your airframe will turn out). I'm using an NTM 4258 500kv motor, Hobbyking 100A red brick ESC, and it looks like I will need at least a 5800mah 6s lipo to have a chance at getting the CG in the right spot.
