Fuel Testing

Part of preparing for the first flight is making sure the fuel tanks and fuel lines are clear of any construction crud. While flushing the tanks and lines I calibrated the fuel gauges which required adding two gallons at a time to tell the computers how to accurately measure the fuel. I also checked the flow rate of the electric backup fuel pump. Here's one of the filters I used. I have a big stack of them and change them often.

Here's my temporary fuel shutoff valve that I used to fill the gas can for transfer and calibration. Not in the picture is my grounding wire to prevent static issues.

Engine Start

Ready for my first engine start. Well, actually, it's not the first. I started it last week but the timing was off which made it run rough. With some help from Gafford Aero, I corrected the minor timing problem and now it runs like a sewing machine. No leaks or runs and the only problem is an incorrect oil pressure sensor. Dynon is sending me the correct one so I'm using an external gauge for the oil pressure until it gets here.

Video of the engine start. The prop looks like spaghetti because of the video frame rate of an iphone matches the rpm or something technical like that. Don't worry, it's not melting.

Wing Jack

I built a wing jack so I could service the tires and brakes easier. Works great and I used it today to while working on the brakes. The hydraulic ram is from Harbor Freight and the legs are electrical conduit.
