Well guys, no maiden today due to "issues". Let's call it an engine run-up test and declare it extremely successful (just quietly, I was surprised with how much power this machine has. Holy cr*p Batman!).
The forward tilting of the swash without command gave me the heebie jeebies so I aborted the lift-off. Need to know what is happening there before my blades are hurled in to orbit in the event there is contact with the ground.
Some quick test results: not the FBL set-up, not the balance of the blades causing vibration, not the swash levelling at zero pitch. Me thinks the CofG could be out a tad and the FBL system is trying to overcompensate. My theory only. Need to know before next weekend when maiden attempt #2 comes along.
Edit: Close inspection revealed the main gear was rubbing against the frame under power. Despite the fitting of the correct spacer per manual, a second spacer had to fitted to give the needed clearance. This was the source of the "extreme vibration" in the event log of the VBar system.
