I tried to get that collection of aircraft for WWIIalso john.
I ended up with over 2000 models still trying to thin it out:lol
I had every version of the 109,190,spit hurricane,p-51 ,p-47,p-40 etc,etc,etc
I work with resin,plastic,vacuform and wood.Then I had to start with the reference material.Lots of bucks there:lol
I decided to settle on Japanese as it was more challaging because of the lack of reference,even had to learn how to read a little japanese.
It,s a great hobby and now I live in Dayton and have a huge museum for all other reference except japanese:lol
As for cobra.Tamiya makes awesome kits and so does trumpeter.The f-16 is the only new kit from Tamiya in 1/32.Academy is the best bet foe f-18.
I have had the great opputunity to have a booth next to Black Box at 3 shows.His stuff is awesome and fits perfect if you follow his instructions.This is the same guy who made KMC resin.Just him,his wife and 2 workers do all the work.He is the only designer.He is currently working on the conversion for the Trumpeter 1/32 Avenger to make it an eary 1-C and hopes to release it at the national convention in Atlanta.
