Now that all the big pieces are in place lots of engineering and fabrication is taking place to accommodate the "custom" part of the Doyle Stearman. We are designing, fabricating and installing an inverted fuel and oil system. Thankfully we're getting by on this one with help from our friends. A huge thank you to all of you out there that are chipping in. The goal is to have a continuous inverted oil system. Another aspect to this build is the fuel injection system. A custom plenum was fabricated yesterday as well as the oil cooler mount and its air plenum. As all you other builders out there know, it's not just about getting the part(s) to fit, they all need to get along and perform!
