Part 103 eligibility
Contemporary club/dealer coverage and community consensus treated the Ultralight Butterfly as a Part 103–aimed single-seat gyro (empty marketed under 254 lb; 5 gal fuel). Manufacturer site thebutterflyllc.com is defunct; dedicated manufacturer numeric product-spec archive not retrieved at research time. Actual eligibility depends on the finished aircraft meeting 14 CFR Part 103 limits (not independently verified here). Separate from Monarch / Golden / Aurora / Emperor / Super Sky Cycle (heavier / multi-seat / roadable) and from the unrelated Butterfly Banty fixed-wing.
