If most of these eppg developers have a gas motor history they're probably thinking this is "quiet"

The 19kw Green1 has a Lipo battery that can initially climb at aprox 500 fpm and can sustain the aircraft at a very smooth and quiet cruise for up to 1 hour with no pollution. Our other battery options can allow for as little as 20 minutes or up to 2 hours power on, which makes the eUP electric propulsion system ideal for self launch motor gliders or local recreational flying. Flight training to UL license will be available at the Freedom Flight Park near Lumby BC starting in April, and many other locations around North America soon.
