Sorry for the late reply. Didn't have a scale at hand which measures above 2kg. It did took me a week (shame shame) to figure out how I would measure the AUW with enough precision.
Finally realized Icould put the parts separatly on the scale ...

Wing:1160g
Fuselage:1855g
Battery:488g
For an AUW of 3503g (approx 7lb 11oz)
Not really happy to report Ifailed my original plan big time. But then again, a lot of the original plan has changed along the way.

Third flight today, with lots of wind. The plan was grounded for the whole day as Iwas to anxious to fly it in such a wind. By the end of the day, however, I bit the bullet as Ididn't bring the plane to the field only to look pretty in the pits.
Less nervous than with the previous flight ... and no photographer to steel my attention, Imanaged to fly "normal" circuits.
In the meantime Ihad swapped the 13x8x3 master airscrew (drawing 32A at WOT) for a 14x7x3 (34A). Flew a tad over half throttle. Strange thing is that Inow flew for 6min30 and put back only 2150mAh, while previous flight was over the 2600mAh for less duration. Iguess the 14x7x3 unloads more in the air ... or the strong wind provided for more lift with less throttle.
Landing this time was as gentle as possible. Others reported that the airplane was like a feather, so smooth the flying and landing occured to them.
No damage done to the plane and my ego got a serious boost.

The picture attached was taken during one of the last circuits. Although somewhat dark and without details it represents the look Ihave been wanting to fly for years. This plane made it happen.
Thanks to all for the help, tips and support.
