P-40E WarHawk....I think the 68" will be good for a 40 to 50 cc engine. There should be a market for that. For example the GP Pitts sells real well and is perfect for that engine size. The 77" I think will be too small. Kinda stuck in the middle. Probably good for a 60cc but too small for an 80cc. Something in the 80" or so range will probably be good. Reasonable enough in size to be transported in a decent size vehicle without the use of a trailer. The 105" one will be basically for the rich. I don't think the common man can afford it and all the things that go with it. But each his own. My personal opinion.
