Maybe. I'm thinking that the CarbonCub SS LSA with it's 180hp might benefit from a GW increase since it already has E-AB and Far 23 brothers and sisters.

Is no night flying part of LSA? I thought if you had a PP ticket and "downgraded" to LSA, you could still fly at night, or if you had a sport pilot ticket you could do some training and fly at night.

Sorry, thinking about the pilot, not the plane.

You should also remove "No IFR". Again, that's a pilot rule, not aircraft.

How would that change a plane like the Sling2? Which I believe when experimental built or is sold outside the US, can have a gross weight of 1540 lbs. no structural difference, just paper. Do you think there would be a way to up the weight?

The Sling was designed to meet the EASA CS-VLA (Very Light Aeroplanes) Specification which allows a MAUW of 700 kg (1540 lb).

Let's say that the FAA changes the gross weight/stall speed restriction to a kinetic energy restriction.

A 1320 lb. LSA with a stall speed of 45 knots has the same kinetic energy at stall as an 1850 lb. plane with a stall speed of 39 knots, using e = 1/2 mV^2.

Now, that would allow a lot of flexibility in design... but the low stall speeds may have troublesome crosswind issues.

Don't forget about the guys (somewhere in Florida I think?), who were selling RV-9's as Light Sport by claiming to have optimized the build for extreme weight reduction during construction... Power limited to 50% throttle after takeoff or some such silliness.

Dreaming is nice, and of course anything is possible, but I wouldn't hold my breath on this one.
