JJ's trim handle technique seems the best in-flight indicator, and requires no additional sensors.
What happened to the "That Looks About Right" technique? Isn't that how it all ends up?
The Blanik L13 was great for TLAR. If it went over on the nose when you climbed in the C/G was too far forward, so put the big pilot in the back. The DG1000 is similar, but waits until the wheel brake is applied on landing... Ask the USAF TPS.
From experience, an LS4 with 70 liters of water in the cockpit is beyond the forward C/G limit. Also from experience the Nimbus 3 at 108% and ASW27 at 112% fly nicely.
Wondering what the CG position on XX's test flight of the same N3 with the broken Mercury weight shift system was.
