ED there actually less vintage than you would think

the Skyshark Hellcat kit is a virtual copy of the Heritage kit http://www.skysharkrc.com/category/F6F-Hellcat-Kit-71 matter of fact Skyshark has a fiberglass cowl for the kit if you want to buy one from them Vs the plastic one that comes in the box

I happen to have 2 of these kits new in the box one has never even been opened and the other was slightly damaged by UPS the one I am likely to build I need to get through some other projects first
