I just finished my Byron hellcat last month. My overall opinion of the kit is that the materials used and scale appearnace are excellant! My only criticism is that the kit uses old technology. Remember, my kit was one of the original Byron kits. I made lots of modifications using today's hardware, etc., and also completely revamping servo locations, flap set up, elevator set up, etc. If you want more info after you get started, give me a shout. Plane came out absolutely beautiful and I am extremely happy. Needed almost five pounds in the nose, located at the very from ridge of the cowl. My cowl feels like there is a brick in it. However, I have been told by Byron Hellcat vets that the weight is not only normal, but actually makes the thing fly better. I guess I'll find out in the near future. I'll get pics on RCU asap. Good luck. By the way, my bird is sporting a G-62 which fits beautifully in the cowl.
