Hi,
I bought a CJM Mig-15 with all of the options including AMT Mercury in early 1999, based on its performance at Superman 1998.
I was not impressed with the gear, (they looked crude and some parts were rusty). The wing is foam sheeted with 2 aluminum spars and the gear blocks installed, it looks nice. The elevators are very small. The cockpit does not have any instructions, and needs to be cut way down to fit between the inlets. The pilot is heavy, his legs need to be removed. The glass work is preprimed, and it looks pretty good, but the canopy hatch needs at least 1/8" of filler to mate with the fuselage.
I have only spent 5 hours building it, so I am not an expert on this plane.
I have plan built 4 Ziroli warbirds and other plan planes, and they do not seem like too much more building and engineering than the Mig kit. I have also built 4 Kangaroos, 2 are ready to test fly today, I think the Fibreclassics Kangaroos are much more strait foward than the Mig kit.
I hope this helps,
John
