Don't think GP/Tower is on the right track here. I used to have a GP Reactor with a Saito .82, and loved the way it flew. However, it has 170 sq in more wing, and weighed 5.5lbs. Don't think this plane is gonna 3D that well at 5-5.5lbs...

Flew a pre-production and this thing was quite impressive. I wasn't sure what has changed for the production model.
I believe I was just under 5lb with a .46 glow. With that setup it was pretty quick in 3D maneuvers and was hands off harrier and KE.
Price isn't too bad either. I remember paying 189 for a UCD way back when. I'll probably pick one up and do a .46 with ultrathrust combo but I have to sell my big yak first.
I am very interested to see what others think of the flight performance.

I got one in for an upcoming RCU review. It is quite nice. It came out slightly nose heavy with the recommended os55. Still breaking in the engine but it flew nice for the first few tanks. KE has roll and elevator coupling which might go away once I shift the cg rearwards. Did not try and 3d yet but I like how it flies as a sport plane so far.

The .55 is ~1.5 oz heavier you will have slight roll coupling, get the CG right and most of it will go away. Keep us posted!
Edit:
It is a little F3A'ish but it surprised the heck out of me when I went to 60deg elevator throw and it just sat there. I could almost hear it say "... and you thought I was going to snap".

Got a couple of nice flights on the Razor3d now. With the CG shifted rear a little bit, the KE is now almost hands off and it tracks very nicely through maneuvers. As far as 3D, it can do pretty much everything though the weight and the 2-stroke make it a little hard to perform maneuvers flawlessly. I am curious as to what others are have observed.
Here is a video of it in action.

Its nice but there seems to be a lot of wing rock in the harrier and a lot of corrections required in the hover. If it has flat wingtips, may be you can consider installing SFGs. What was the setup used for the flight?

From the look and feel, I think the Razor is very similar to another model- the Quest 50 from CMPro.

This is a re-make of the Lanier Razor 3D that was discontinued about five years ago. It had a neat elevator bellcrank/control horn design, but this one does not appear to have that.

Wing rock and hover corrections are probably due to it being a little heavy with a .55 and added tail weight. Also might have something to do with that wind noise I can hear on the video.
Great Job. Enjoy!
Patto, Direct linkages, much better.

looks like a U-CAN-DO variant, which in relative terms today is an ancient design for a 3D model. The long tail looks more oriented toward a hybrid pattern/3d flight similar to a 3DHS vyper or EF Vanquish. I'm sure it'll fly like it's "on rails" like most pattern birds.
