Well all the OMP planes are different animals all together. The Cedar witch I don't want to say much about because of a previous incident here on RCU involving me and a distributer of them. To say the least the issue was resolved and in more ways than one I am glad we don't see those things around here anymore. The quality of those planes were not great but I guess in the same breath one should consider the price involved. Now a simple note to make is that you don't see guys posting videos or anything of them and that should say something about the plane already. I haven't flown one myself but I have seen them in person. I just don't think it's going to get anywhere near a OMP plane flight performance wise. If you're serious about 3D get something that's proven to work many times over rather and avoid extra hassles.

The OMP Edge/Yak/Katana reviews have been posted too many a times so a quick search should yield you hours of endless reading. I'll try to sum it up quickly.

OMP 47" Edge: The best 3D trainer out there today. Super silly stable in hovers/harriers etc and very forgiving. The compromise is the agility in the air. Still does awesome flat spins etc.

OMP 47" Yak: Very stable just like it's brother the Edge but a little more loose in the air. (By the way I fly one currently). This one has awesome rudder authority and will do pinwheels with great ease. Very manuverable little plane and awesome at spins be it flat/knife edge or just wacky. Does great upright/inverted/rolling harriers too. High alpha knife edge is a breeze with all the tail authority. Tight knife edge loops you name it. Compromise is you have to be a little more awake than with the Edge on this plane.

Katana: Well something like the Yak but with different handling. (I haven't flown the Edge or the Katana ARF [I own the kit version] but I watched lotsa videos and read alot). When I say something like the Yak I mean it's also a little more loose in the air and not quite as super stable. Great Knife edge characteristics and will also do it all. Flat spins/tumbles/waterfalls you name it but not quite a pinwheel like the Yak.

If you need more help let me know.
