Hi Rune,
We missed you at the nationals, great event!

... Mine came out at 4940.
That is with "heavy-duty-battery pack`s" ; 5000-25C. (Hyperion G3, Zippy-R, polyquest). These weigh approx 1250gram.
I haven`t done any special to the airframe, or equipment, just converted as it is.

p.s.
Chivas !?
We all are going ! :-)
