Hello Dan and Net.
A similar scale trick can be done with one bath scale and a two foot board
of sufficient strength, Such as a 2X6. On one end of the 2X6 needs an end
board attached equal in height to the top of the scale, and the other end
sits on the scale. The wheel sits at the half way point of the board. The
scale will read 1/2 of the actual weight.
In my opinion for no reason should you attempt lift off prior to determining
the weight and balance of the aircraft with a bathroom scale or a certified
aircraft scale. If you take off without a weight test you may find your
nose too high, too fast and damage your craft. The KR is much too quick an
aircraft to experiment with unless you are very familiar with it. Always be
completely ready to fly when you go onto the runway even if only for HS taxi
testing.
