I just launched a 2m APRS one with the SBS-12 envelope. Although I'm a bit over the recommended free lift of 4 grams. It is somewhere between 5.2 to 5.5 grams free lift.
This one is Solar-powered only
with Supercaps. Payload weighs 14.80 grams but after the string and tape
it is 15.80 grams for payload, string and tape. Free lift around 5.2
to 5.5 grams.
APRS on 144.390 FM as well as 144.340 MHz FM every 2 minutes.

Inflated and launched by myself in a light wind with no problems.
flight path is across north GA, north SC and then out to sea near
Wilmington NC. Probably will stop transmitting just east of Charlotte
due to sunset.
