I've noticed on my SN10 that the final glide height
needed is excessive. I'm comparing it to GNII driven by a 302A. The GN setup is faultless and the SN10 can demand twice the height needed as calc by GNII. When I flew on Saturday, the Ilec needed around 8000 ft and GN said 4500 feet, GN was correct. Roughly 45 K glide, Ventus C. I remembered to set the wind on the Ilec, distances looked right, winds on Ilec and GN agreed. Any ideas ? John |

You didn't mention MacReady, wind, safety altitude and field altitude.

Did it work properly and then malfunction lately?

Review the settings for: - polar (correct glider and your personal dry gross weight) - FIN finish altitude setting - bugs/water Let us know if you find what's set wrong; if you can't shoot me an email with contact phone/time and I'll try help you (currently flying my Antares at the Open Nats but the weather looks dubious)...
