Ok good to know that it is legal and theoretically possible.
Worth remembering though that the aircraft willl feel noticeably more sluggish than you are used to. It will be ready to fly at a higher speed and its initial climb will be poor - compared with what you are used to. If you add in a hot day the effects will all be magnified.
So the first time, if you are used to popping off the ground it will not happen - don't keep the nose up - let the speed build and the aircraft fly itself off. Depending on the aircraft the differences between 'light' and 'heavy' can be pretty dramatic, trying to do what you are used to may not work.
