Hey man, Its been a while since I checked this video!From what I remember everything is stock, stock chassis. Sbc fuel injected. It's been sitting for a long time. Everything needs to replaced now, but it sat because it was over heating, need a bigger fuel injections and better cooling radiator. My good friends uncle built it he was a Helicopter Mechanic in the US military. Super cool build. When it gets running again I'll post another video 😎🤙🏽 aloha
