Well, it's going to be a little more time and a lot more money before this plane gets off the ground.
I ordered a Smart-Fly dual ignition cutoff for it, and it came in this past week. I had previously been running on a single ignition cutoff and a Y-cable, but I never intended to fly it like that. So, today I installed the new cutoff, wired up the ignition modules and drug it outside for a quick test.
About 30 seconds into the warm-up, maybe about half throttle, it started sounding like someone threw some extra parts into the crank case. I stopped immediately, said some extra words, then took it back into the basement for a closer look.
All of the pistons are still moving, and they seem to hold compression, but the bearings do "knock" more than they should as the cylinders pressurize and release pressure. It may not the the broken crank that I feared, maybe just a bearing or something, but as bad as things were slapping around, I need to send the motor down to Gerhard for service.
I'm glad I wasn't just lifting off the runway when this happened. We'll see what Aircraft International has to say when they get to it.
