Some things to think about. We 'Murikanz are a laz… err instant gratification bunch. While an artisan type kit (ala the laser Banta cab conversions, or the Ozark Climax) would appeal to a small niche (of those having inclination, ability AND some fairly serious money to pay for it), they probably won’t fly off the shelves.
A plastic kit (along the lines of the Hartland mini cars, or maybe a bit more detailed, but still able to be assembled by those with a moderate skill level) might give you a wider audience. But since it’s P-L-A-S-T-I-C folks will also expect it to cost less… go figure
The LS hobby in America is fragmented into nearly half a dozen scales. Which SHOULD mean something adaptively generic would be a good thing… except we’re also the pickiest bloody beggers on the planet. We want what we WANT, and not much else. If you ask 100 guys what that is, you’ll get at least 50 answers, and a lot of squabbling if you tried to get them come to any sort of consensus. It’s often much easier to go the route of making something YOU like and either folks will buy it or not…
And BTW we also want it as lowest priced as possible. (as opposed to “cheap” quality wise… we want good stuff, we’re often just generally disinclined to actually pay for it) And we will ALWAYS complain about the price, even when it’s reasonable. B#tching (not baseball) is our national pasttime.
At any rate the adage of “the only way to make a small fortune in the hobby business… is to start with a large one.” has a lot of truth in it. If you’re going to make something, then do it because YOU are passionate about it, that way IF you make money doing so, it’s a bonus. And lastly, gambling with the groceries is always a real bad idea. Make darn sure that if whatever you plan flops, you won’t lose everything.
Other than that, have fun!
