DesertRacer Posted March 1, 2003 Author Report Share Posted March 1, 2003 Ahh "twin" probably should have tipped me off on that. I just haven't heard much about those, are they not that popular? Quote Link to comment Share on other sites More sharing options...
Robbie Driver Posted March 2, 2003 Report Share Posted March 2, 2003 Could anyone with A-Star and/or Twin Star verify the fuel capacity for each aircraft. Are they the same? thanks,RD Quote Link to comment Share on other sites More sharing options...
T-rex Posted March 3, 2003 Report Share Posted March 3, 2003 Fuel tank in an Astar is 540 liters. The Twin star has two tanks I believe, with about the same capacity! Quote Link to comment Share on other sites More sharing options...
Gummy Posted March 3, 2003 Report Share Posted March 3, 2003 T A-Star, or Squirrel as they are known in Aus, is the AS-350, and the twin is the AS-355. The twin has to have separate tanks. This is for the "engine out option", contaminated fuel, hole in tank, ect....Try this link ( for full details you will have to download the PDF)Eurocopter Quote Link to comment Share on other sites More sharing options...
Wally Posted March 3, 2003 Report Share Posted March 3, 2003 Twinstar-2 Allison 250s until beyond the 355F series. (N's are Turbomecas, I think.)355-F1 grosses 5291, empty wt approx 3050, cruises 120 or so when light and drops to 115 at gross. Uses 60 gal per hour out of 191 (or so-been a long time) in two tanks-106 forward and 85 aft? Two mechanically driven hyraulic systems, duplication except tail rotor servo.Reasonable single engine performance for it's era.F-2 grosses 5600, approx same empty weight, etc. You lose some cruise speed and single engine capability at higher gross compared to the F1.You lose a lot of weight fueling that second engine compared to the 350B. I prefer the Astar, excepting- engine out performance; and the belt(!) driven single hydraulic.350B, empty weights I've seen-3000 lbs, gross 4300, cruises a little better than 120 and a joy to fly at 45 gal out of a single, unbaffled 143 gal tank.350B2, a few pounds heavier, more horses than the 350B, and the Twinstar rotor system. Little more stable. All the useful power I ever need at the altitudes I work. 48 gals an hour, same tank, and slightly slower than the B-which all relates to gross, like the 355... A 350-B2 will fly farther, faster, cheaper and easier on the pilot, than the 355F's-again excepting engine out performance. No experience with the N's or newer AStars-B3's and EC 130.
