Sorry, I will build a couple of these some point, but I will not sell "kits" of my designs anymore.      After I had nearly 20 people that just HAD to have kits of my Viper and everyone said "put my name on the list, I WANT ONE!"       Well, I had a list of just under 20 names so I'm a man of my word and I got coordinated to sell kits.
Any guesses on how many on that list bought them?       ZERO......ZIP......Nadda.       People don'g realize that saying "I WANT ONE"    "Put me on the list I can't wait to build one" does not mean anything unless you actually intend to do that.      I had no plans to sell kits ever, so I invested $15k in further prototypes, molds, materials, etc. and to date we have sold THREE.         All three of those have been at a discounted price barely above materials cost.
Sorry, no kits but I encourage everyone to explore scratch building as it's very rewarding but I will absolutely not offer kits again.
sorry
