Netters;
After one has "done the math", and you think you have the weight and
balance close, apply a practical test to the situation. Taxi on to a long
runway. Power up and go roaring down the runway. Gently apply forward
pressure on the stick in order to get the tail up. Once the tail is up, apply
gentle back pressure until you get the mains off. Fly about 5 feet above the
runway for a short distance and make a subjective judgement concerning the
correctness of your balance. If you can fly comfortably in ground effect, you
will probably be OK to fly your KR out of ground effect. You may want to do
this several times before you commit yourself to a trip "around the patch".
Caution is the key. Don't rush into flight after having spent several years
building another great KR!
