Bamatim go check out the fun fly and profile planes forum. Plenty of threads going on both the kit and the arf. Couple of flying reports as well. I'm sure you'll be able to make up your mind on those. There is a difference between the kit and the arf of course as the kit was desighned by a fellow Bro and the arf by a completely different company. OMP describes the three 40 sized birds in different levels of flight characteristics. The edge of course for stability and the first step if you will. The katana is one step up from there with a little bit more agility. And then the yak is on top with the most control authority really the beast of em all if you will. But of course the yak is the less stable one. Not making it a beast to fly but just a little bit more of finger tweaker if you will. A little more capable in the high alpha department. I am working on a 47" Yak from OMP and well planning on having all three birds in the near future.

Oh be sure to also check out the profile brotherhood forum as I can not remember for certain but pretty sure there was more there as well.
