The 4*'s go together VERY easilly. The 4*40 reminded me of the old Snap-tite plastic models, in the simplicity of construction. The 4*60, I built in my hands... no board. (not a good idea for a beginner at building... there's a trick to it.)

For 90% of the construction, recommend using yellow glue instead of CA. Its much better for assembling lite ply. And how much difference is there in: Pin part in place, add CA, or Apply yelllow glue, pin part in place. ? The yellow gives a bit of time to realign if you see you got something crooked too.

See the kit reviews section. LOTS of hints on the 4*'s.
