Empty Wt & Measurements

[Andy J]

...and a very great looking airplane.

Thanks for the detailed data. I'm still a couple months from weigh in, but getting closer everyday.

One more data point.
"Sweetie" - N412BR:
750.5 lbs empty
Empty Moment Arm 82.09
Empty Moment 61605.1

Has AP servos
One Skyview screen, standard avionics.
Full interior and carpet.
Lighting kit.
Comprehensive multi-coat full exterior paint.
Not very much interior primer e/x mating surfaces, but full primer and paint inside in the cockpit area.

Nosewheel measurement 39.75", Main wheels both 23.25"
Left main 304.5 lb, Right Main 313 lb, Nosewheel 133 lb.
Includes weight of the hose for relocation of the oil pressure sender!

Above numbers are WITHOUT wheel pants mounted.

2 BIG 200lb guys, full fuel, full baggage is right at gross weight and well within aft CG. Full fuel burn has arrival within CG as well.

Now, a *very* lightweight pilot, full fuel and baggage would be slightly aft of the CG range. So some baggage in the passenger seat for that case!

Very nice capability!

"All in all, a very nicely designed LSA.

And built too! A fine airplane and beautiful. I know - I've been lucky enough to fly as F/O with Capt. Tony.

N328KL weighed in at :

154 on the nose

I was pleasantly surprised by my empty weight a couple of weeks ago.

Oil & coolant in engine
Skyview avionics
Autopilot with servos
Lighting kit
No primer or paint throughout

Total empty weight = 718 pounds on a set of computerized and calibrated aircraft scales. I'm delighted!

Jerry... I'm not meaning to be critical... just making a comment to help other builders wondering why they get different numbers.

I have enough experience with multiple RV-12's to say with some level of confidence that I think your weight number is low by 8 - 10 lbs (but maybe you put helium in your tires ).

RV builders should probably expect an airplane equivalent to yours to weigh in the neighborhood of 728, or so.

Congrats. on finishing. Looking fwd to seeing all of the new RV-12 at the many fly-ins this summer.

Scott,

For the past week, I've been wondering what could've been left off when we weighed the plane. Nothing has come to mind. I've also been mentally reviewing the construction of each sub-assembly, searching for weight-saving tips. Again, nothing except for leaving all alclad aluminum unprimed and unpainted. I did spend an excessive amount of time throughout the project deburring and sanding smooth all edges of every single piece throughout the entire plane. For instance, I spent four solid weeks on the wing ribs alone. Could I have collectively sanded off ten pounds of alumumum over the past three years? I doubt it, but it sure looks pretty. I'll keep this concern in mind and will try to perform another weight and balance with a different set of scales.

At 727 empty, arm of 80.49 and moment at 85217 (empty)... Myself at 175lbs and 15 gal of fuel, nowhere near the envelope. Even adding 100lbs of ballast in the passenger seat, still not close..... On paper. Anyone else have this issue ??

[Catbird]

I haven't flown N562E yet, but have a brand new Airworthiness Certificate, Operating Limitations, and no excuses except for work and weather. In order to come up to the 1050 lb gross weight for the first test flight, I'll need the plane at 718 lb, me at 210 lb fully clothed and wired for sound, 15 gallons of fuel, and 32 lb of ballast strapped into the passenger seat.

[Catbird]

Hey, wait a minute...

727 lb empty plane
175 lb pilot
90 lb fuel
58 lb ballast

Adds up to 1050 lb GW for first flight.
