The design, construction layout and materials (in my kit) were first rate. I would have preferred a different nose construction would have allowed the builder some flexability of engine mount choice, but MK has used that same basic layout for 20 years.
It's amazing how such a big model comes in such a smal box. The fuselage involves a little thinking ahead, but is a fun build and nothing difficult. Wings are easy. Stabilizer was probably hardest single item for me, hard to keep straight but some homemade jigs did the trick.

The come with no hardware, I did use the optional MK landing gear- has been fine, a Bolly may well be lighter however.

I have built over a dozen MK kits & will build more, very well thought out designs in general, and a first rate build. Fun
