RE: Intermediate warbird
acdii,
Then, take a close look at the Great Planes corsair and Mustang. Go to GP website and download the building manuals so you can assess the building process. You can compare to the building manuals of Top Flite wardbirds too. That's what I do when undecided about purchasing certain kit.
I am at the final stage of building a TF Spitfire. I have not accounted the number of hours invested in that plane, but certainly can say that I am close and over 150 hours so far and still have over 50 hours to go.
Hope it helps,
Pedro
