Finally the fateful has arrived to see if all this assembly of airplane parts actually can actually make airplane noises.
I went through all the pre-oiling procedures discussed on VAF and in the Lyc doc SI-1241C, tested for good oil pressure, fuel pressure, fuel flow, the whole nine yards. All good.
Towed the plane to the nearest pad that had a pad-eye, tied her down, hooked up a car-sized battery in lieu the little Odyssey - in case there were lots of cranking involved
Turns out that the external battery was soft and it had a hard time turning the engine over with the plugs in. However, it only took one blade to start once it got around and then we're off the the races!
