I might add that a higher gross weight also raises the stalling speed. Already at around 1750 lbs you may reach 60 MPH stalling speed according to my calculations.
The airframe does not support much more. It was never designed for that task of hauling more than 1500 pounds. While the airframe can be stressed by a certain factor, the wings can only produce so much lift at a certain speed. Herein lies the limit.

As you may be aware or Not the coupe in its original form ie: without mods is very difficult to get out of CG regardless of the load in W&B calculations however keep in mind the HP required to lift and pull it as long as the CG is not violated. Remember MAX Conrad a somewhat 50,000 hour pilot flew around the world in a SE Commanche some 2000 lbs over gross but in CG range most certified aircraft frames are stressed tested to 3.8 times the gross weight prior to being FAA certified ie: 1260 x 3.8= 4,788 lbs. keep in mind CG and HP and trim I would not recommend flying over gross to anyone this is just computations and the engineering incorporated by any certified aircraft manufacturer. flyboy _________________________________________________________________ With Windows Live, you can organize, edit, and share your photos. http://www.windowslive.com/Desktop/PhotoGallery
