REFLECTOR: Max takeoff weight - Standard?

[Stockman, Bill]

I've taken off in my 173FGE with an IO360 C1C and a CATO fixed pitch prop 
--with only me in less than 1000 ft
--probably 200+ lbs overweight in less than 3000 ft.
--takeoff is far more sensitive to the forward CG in  my plane than the gross weight.   
--for the fixed pitch 200 hp folks, there is a huge difference in take off performance between single pilot, low gas takeoffs and climb and full gross with your friends.  By myself on a nice day I'm climbing out in the 1500+ ft/min, but with full gross its closer to 100-200 ft initial climb rate--which feels like you are not climbing.     Even at 500 ft/min (which is good for most Warriors and C-172s), you still feel like you are not climbing.   Just spoiled. 

I did my first flights and first ten years at Moraine airport south of Dayton Ohio (850 asl) with two 30 ft river levees abutting the ends of both runways, so this was always an issue on take-off to consider.  You just had to learn that clearing the levee by 5 ft was okay on some days and watch your airspeed.   One of the biggest issues I see with our new pilots is they don't fly their best airspeed on take-off and landing.  Part of your test program is to determine your safe range of airspeed on landings, take-offs and pattern maneuvers and then use them.  While my first 50 hrs were probably exciting, I have found the Velocity to be simply outstanding in all phases of operation once you learn to fly your plane.     

One of our first international builders use to load up his 173FGE with full gas, four real adults and stuff (probably 300+ lbs overgross) and take over 4000 ft to lift off the runway at Manassas in VA.   Landings were quite long and he eventually caused the meltdown of a gear leg.

Just wondering how much any of you have put in your plane and how long it took off over say 50 ft? 

I have a 200HP lycoming and MT. I've never really loaded it up. Maybe 2300 or so. Took me about 2500 with a 10 kt headwind at about 1000 ft DA.
