Nice engineering and extremely clean work. Sorry to read that they're no longer in production. The backyard flyer it is or was one of the more sound Ultra Lights. Hope you are doing well. Talent like yours should not be wasted. take care
There is no certification that I know of. There is how however certain FAA guidelines to follow for certified aircraft and will also need to be inspected by an A&P or someone else certified to do so. Our ultralights require no certification or inspections.
I remember the old man that built the original, state in a video while sitting in the seat of his creation, hanging from the wing, that None of the critical welds were in tension......When you weld aluminum, the heat affected zone returns to Zero temper, meaning it has a tension value around 8,000 psi vs 40,000 of T3 or T6 temper.... .th-cam.com/video/uaUe8uT-CtM/w-d-xo.html,,, around (07:35 ), other than that, the aeroplane is very well thought out.....
Nice Job! Great craftsmanship. Thank you!
Really enjoy watching how you go about fitting things up
I really like your material selection and construction techniques. Keep up the good work!
Really enjoying your videos !
