Weight & Balance and Fuel Capacity?

Nice! I'll go scope those out, thanks David!

There are a few examples of approved 337's on this site for light weight batteries. I just got approved for an earth x battery and a b and c alternator, I'm anticipating about 25lbs saving on that upgrade. The alternator is a lot of work and pricey, but the battery is paperwork and $450. I figure an airplane manufacturer would gladly pay thousands to save 20lbs in a design, so I figure it's cheap.

Got the weights & balance from the mechanic, 843 empty (weighed on scales) I do have the rudder kit though no AI as well; 1320 max, has the 1320 STC with the 9 degree limited elevator with the necessary mod, I believe it is 21 Gallon max fuel.

"One thing, you will notice when the passenger gets out of the airplane, it starts to fly like it wants to have more fun..."

Gotta admit... I'm looking forward to that!

Ron R,
"The plane may have weight 750 when it was born, but that was bare naked. No electrics, battery, interior, paint, rudder pedals, etc. They have all grown up since then. Somewhere around 900 is more typical for our geriatric planes."

Just like me then, packing on some "padding" with age... I'd love to get her back down to that "fighting weight" and in '46 livery but the prospect of hand propping... Any weight savings I can get. I suspect back then they hand propped a lot of the time? I've a LOT to learn in a short amount of time!

Does anyone know if during WWII any Ercoupes carried 200/250lb GP bombs when Civil Air Patrol used them for anti-sub patrols? I know C.A.P sunk two Nazi subs during the war, probably from J-3's.

  I just did the 1320 STC a couple of months ago... All paperwork... My instructor and I are probably 430 with bags and headsets... He and I have flown for dozens of hours with full tanks and hot dry Calif weather. I have never had any issues with weight of load... My weight is 824 before us humans and gasoline step in... I have fabric wings and zero rudder pedals... I too have heavy AI and all steam instruments... One thing, you will notice when the passenger gets out of the airplane, it starts to fly like it wants to have more fun...

Roger that and agreed, never want to go over gross, goal is to keep it safe and get home in one piece to show it off to my wife.
