I recall weighing my Firestar I, it came in at ~180 lbs with no engine or
prop. Or instruments.

I can't see any way, unless you come up with a super light engine of some
sort. Maybe something like the MZ201 (69 lbs) incl. reduction, electric
starter, exhaust. But you'd hafta add the prop, battery, etc. I've seen em
fly just fine on the Rotax 377, but that's 85 lbs. My 503 is right at 100
lbs I believe.
I can't comment on the rest of your questions.

Sorry to butt in on an ultralight discussion.... you Ultrastar and Firefly guys NEED to check out the Polini and Simonini engine websites. There are many many many pounds of weight to be saved by using the later engines from the paramotor community. There is a very good chance you will have more power, LESS WEIGHT and higher reliability by using one of these newer engines. ANYONE trying to meet Part 103 needs to be familiar with these engines.

George,
Thanks for the info, its actually a lighter number than I expected. Maybe with a Simonini and Oratex covering it would make the 254 limit...
Does anyone know the approximate weight of the Firestar I fabric?

Approximate weight... well ... today I finished welding the gear leg brackets, hopefully this week we will be able to weigh the fuselage cage/boom/tail/wings and get an idea of what the empty weight is.
Or not. The WX forcast is crappy.
But as soon as we do, we will let you know.
