Due to various issues, I did not use all of the Alley Cat items, most notably the small wing bulges (fit issues), spinner (off-center) and gun cowling (warped). I thought the Revell kit was excellent... good fit, great detail and lots of options including separately molded control surfaces. There were some headscratching choices made by Revell (landing gear molded into three separate parts, modular wing assembly) but the good fit made up for it.
