Wow, thanks a lot. Obviously the J85 is totally impractical for use in a Cozy or related craft. I just really think it would be great to see a relatively affordable, high speed, and aerobatic carnard homebuilt. My actual turbine experience is zero, I've just been a fan of the ViperJet for a long while. Ultimately, I'd like to work on a canard design with similar proportions and performance as the ViperJet. I'm just doing some homework now. Thanks for the help.
