Aircraft assembly, Engine start

I drilled all the small hinge pocket covers ready to fit. They'll remain off until after the final inspection.

Next, I pressurized the fuel system. Immediately a large leak was apparent on both sides of the fuel flow transducer. I removed both fittings and discovered that I hadn't sealed the NPT threads. Once sealed and reassembled it stopped leaking,. I later discovered another leak on the electric fuel pump outlet and tightened the fitting.

Then we pushed the aircraft outside and started it. After priming it caught on the second blade. So "operator error" meant we spent several minutes before I turned the fuel on. Then it ran immediately!

We have two problems to resolve. The prop governor isn't operating at all and I suspect it needs air pressure topping up. Tomorrow I'll remove the spinner and check it.

Also, the RPM was reading over 5000 rpm. I think it probably needs a setting changed in the Dynon menu which I'll do tomorrow as well.

Overall, very happy with progress.
