My title avoided the word “ultralight” even if these two aircraft qualify. The American entry can readily fit FAA’s Part 103 as an Ultralight Vehicle, freeing the pilot from having to register the aircraft, or have a pilot certificate, or possess any sort of “medical” to fly it.
The French entry cannot qualify as a Part 103 but I find it surprising this super lightweight machine is a two seater and can be electric-powered. It is not available in the USA at this time but the brand once had a strong American presence. I owned one of their light trikes myself a couple decades back. Here’s a full review from 2004.
Welcome to brief reviews of two very light weight-shift aircraft, North Wing’s SkyMax and La Mouette’s Samson. (La Mouette is French for seagull.)
That these two are also more affordable may come to the rescue of budgets under assault by persistent inflation.
