Recently we flew with a friend who weighs over 320 pounds. With he and I
in the front seat, and just Mary in the back, we were at the very forward
limits of the allowable CG. Thanks to the Pathfinder's 1400 pound useful
load, however, we were still 250 pounds under gross, even with full tanks --
but the teeter-totter was certainly pretty far to the "teeter" side.


Took a heavy friend and his tiny wife for glider flights once. He was
right on 250 lbs. Put him in the front seat of a Grob 103 (a model
famous for being nose heavy anyway). With the stick all the way back,
airspeed was 60 knots. You can bet I carried some extra speed on final.
His wife was 90 lbs. Bolted in the iron ballast plates and put a chute
on her. She was still a little under the front seat minimum. Flew her
that way since I knew the glider was a little forward CG from a repair.
That was the best that glider ever flew for me.

Now I have a little Stits homebuilt. It is somewhat forward CG solo. So,
I will have some bolt-in ballast for the rear. With anybody in the back
seat, it will be aft CG once a gallon or two of fuel burns. I will have
to add some ballast up front. The most useful ballast I can think of is
an electric starter.
