    Now with the back of the airplane worked out, lets turn our attention back to the front. Before we get too deep, we need to see how the cowling fits. With this STC, some airplanes will have interference with the induction system. The STC allows the induction system to be flipped if this is...

    Moving up on the fuel system. From the header tank, we need to add a return line to get the fuel back up to the tanks. We repurpose the wing root vent lines to be return lines. After a bunch of work, we have all that in. Here you can also see the header tank located down in there. After all...

    On to the fuel system upgrades. xpmods uses a header tank near the pilots knee. Time to get all that located and start drilling holes in the airplane. No turning back now!

    Not long later, parts start arriving. XPMods engine mount and factory overhauled 210hp Continental IO-360 as well as an 80" McCauley. Now the work really begins.

    About 5 months after getting her, the engine gave up the ghost. Wrist pin was walking out and making metal, one trashed piston, cam shaft was wearing on the first lobe, stuck valve, on and on and on...So this started the big build. Off came the engine and mount getting ready for an upgrade.
