uh this is the SAS-51....what makes u think they still using gas bags....it clearly says The SAS-51's pressurized hull is composed of a combination of Tedlar and Mylar that effectively has reduced the helium diffusion rate to one liter per day......thus there is NO gas bags.......the gas bag is the hull......hull sized is fixed.....hull has a max pressure.....meaning it only holds so much H before u blow a hole in it.......the H then leaks out at one liter per day.....so either u add that liter back....or at some point its no longer lighter than air....and will slowly float back down.......really its a mute point anyway......heres the real question.....does it work at nite.....iow does it carry enough battery charge to last thro the nite......if not then it only staying up a day anyway.

oh btw given the max height and weight......u should be able to figure how much helium is needed.....thats how that works right.....or is the max height set by hull pressure....as it raises the outward pressure on the hull will increase cuz the pressure outside the hull decreases....less air.....i know its more important in really high attuides.....but this ship is NOT even going a mile up.TIA

PS running out of post so i'll do this......well no crap sherlock......but when the engines quit running how u steer it at nite......u just hope it don't get windy at nite.LOL.....heck once it runs out of power.....it won't even recieve your commands.
