Gyro-only mode on HSI...

Bob,It would also be nice to have a "free" or not-slaved and adjustable (to calibrate to alternate direction systems) HSI mode so as to be able to use in non-typical navigation situations such as polar and polar grid navigation and such. Of course, it would need to be automatically corrected for precession ( as I am sure it would be in real life) to make it manageable. The existing "Magnetic" and "True" selection option is great, but it would be nice if one had one more option where one could do the calibration manually to any direction system of choice. Many thanks again for this incredible add-on.regards,Macs :)
