Here's another interesting engine, either 15 or 18 or 19 HP depending upon
where you look; 15 pounds!

They also make engine/generator sets and range extenders, don't know if it's
for this one or one of their smaller engines.

Yes, it comes with 19 patents; seems they had a major US uav contract that went on hold some time ago, had to reduce staffing from like twenty to six; imagine what it costs and which private buyer could even get to hold it in their hands... Tougher story than the Engiro RE20-2

i really like that it gets cooler we go higher!

KVA is used for generation because "power factor" is an issue for most
applications.

Thank you, Dave; will hold further questions until after internalizing a power electronics book/course, maybe directly in a few weeks if it's alright (instead of buzzing up the forum)

are you standing next to the propellor in the first picture of this sweet travelogue? http://www.ultralightflyers.org/travelogues/elma.pdf
