Over gross ?
I flew a Cessna 210 for years and many big friends went up but now at least 6 people come to mind that would be a very tight squeeze in the 6A. I can leave half the fuel behind but am I pushing it with somebody scaling out at 280? I'm 185 lbs. My gross is 1850. I have 2 miles of runway but density alt is often 6,000. The numbers say I'm OK but what's the biggest payload you have tried?

230 for pilot, 310 for passenger. Was a tight squeeze. I don't remember the fuel load that day, or weather. Airport elevation is 4607' msl. The 6A with 180 HP C/S prop still had plenty of pep. Also 1850 GW.

Didn't Van himself say that 250 lbs per seat was his design limit? Trying to find where I read that, but not having much luck.

215 for me, 280 for the passenger, full tanks, hot summer day, and only 135 hp.
The -9 did fine.
The problem was flaring to land, the passenger couldn't get his gut in enough. I wound up wheel landing it after going around and beating him in the gut with the stick.

weight ...not so much the issue
I think we all appreciate that at -20 degrees,. with a headwind, the average plane will lift a LOT more than it's placarded for. (Ask a northern bush pilot)
If there's Density Altitiude considerations, I'd have to get out the calculator. Some of you can go by experience, which is probably as good, or better.
I can remove some tools, water, survival gear I gear if I have to ...but truthfully, the side by side RV's aren't that great with large folks.
Not only the pitch limitation, but how many 300 lb-ers have skinny legs?
the control travel side to side is almost more of a concern.
..of course, the removable pass. stick solves most of those. If they really want to 'fly' they can reach over 8" and use the pilot controls.
Also a good point on preflight is where to put their size 12's ....especially on t/off & landing.
some folks have done the wing area/flap calculations, and found that the -9 will lift 2200 lbs. or so....of course, you can't OPerate at that weight without a whole lot of other issues.

Was that a design limit or where Vans "bubba factor" starts?

I don't ever remember a seat design limit in the 6. It's all attached to that ultra heavy duty spar, that the 6's have..

I've never seen a 250 lb seat limit in any of the specs but I have seen that as a stated limit for the max weight of a passenger for a demo ride from Van's at Oshkosh.

If you haven't flown the airplane at that weight before, you owe it to your passenger to ballast the airplane to that weight and fly it before you carry the passenger. My experience is that when the airplane is at the heavy end of the scale, every 50 pounds of weight you add makes a significant change to the airplane's handling.

A better solution would be passengers that weight less than 140 pounds, have longer hair than guys and look better.
