and you have to tell your larger mates to eat less pies!!
Think its 2350lbs max AUW for a -161, and 2550 for an Archer. Engine is a bit heavier of course and usually more buttons in an Archer, so something like 150lbs less payload.
Other than that, I generally agree with what other posters have said - pretty much the same, but a bit extra power for take off and cruising.
