Grega GN-1 W&B
Posted: Tue May 12, 2020 7:26 am
Looking for info on GN-1 W&B.
Found a material error in the builder's calculations on mine that is causing me to want to dive deeper and don't see anything in the plans that conveyed to me. The actual CG is aft of where he said it was, if weights are right.
For anybody with a GN-1 what % of MAC do you use for allowable CG range? Now's a great time to plan some mods while my motor is off and I'm prop-shopping. Might go w/metal if I need weight on the nose. I do have the Wynne Piet W&B manual.
Also interested in as-built empirical data for Grega esp O-200. I promise to to do a writeup and return the favor.
Cheers,
Bob
