I have both the SM 1/5.5 Hawk and the CARF. The SM looks really nice, perfect paint and has a lot more scale details. The glass work on the CARF is much better, the engineering of CARF is much better and the CARF landing gear is much beefier and a superior design. The CARF Hawk is also quite a bit more money than the Skymaster as well when u add in all the extra's that you have to buy with the CARF . The CARF is bigger, another 4 inches or so longer and more span on the wing and stab. I haven't flown the CARF yet so, can't make any comparison there.

From a build perspective, the CARF was a pleasure to build, the SM an aggravation. Everything on the CARF fits.
