I’ve been flying PPG (ICE) for 5 yrs. I also have my tandem exemption and fly both a Moster 185 Foot Launch and a Fly Products Flash Cruiser Trike. I’ve been following the OpenPPG progress from afar. The SP140 is very interesting to me and I’m considering getting one for my Trike to use for short tandem flights or longer solo flights (using 2 batteries and the tandem wing). I live in Northern Virginia and am part of a fairly large PPG group called the AirDogs. Nobody has an ePPG yet but I love all the pros about it.
