I flew the G-109 many times from the Grob factory to the Alps not far away. From an operational standpoint, it was a well-developed design with an easily feathered prop, 2-pitch control, folding wings, etc. It sips fuel, handles nicely without flaws, and has cool novel features such as a speedbrake detent that can be overridden with a little extra control force. Engine starts reliably after extended gliding. Well done! Glide ratio is decent, but it's just too heavy for most updrafts unless you are particularly good at finding strong lift.

The Grob T-1 Vigilant ist a military version of the G-109 Motor Glider.
