On my current build with a forecast weight of 15.5 lbs, it was noted when removing the tail planes from the box that they were unusually heavy (totaling 15+ ounces). A decision was made to build all else and asses the tail planes before mounting. It was found that with the furnished tail planes, 12.5 oz of nose weight was needed to balance.

I determined that if 5oz of tail weight was saved by making replacement tail planes, doing so would eliminated any requirement for nose weight, thus saving 17.5 oz of aircraft weight. In fact, enough was saved to allow bolt on stabs rather than fixed glued stabs and still obtain the 5oz tail diet and the goal.

This proved to have a double benefit because the wing foil uses a Clark Y foil and because of the lift of such a foil, it needs a positive stab to control pitch and such positive angles are a bit hard to estimate... so it helps to have either an adjustable stab or bolt on that can be shimmed. A positive stab is a big plus for such a plane because it then becomes a lifting surface or lifting stab and thus lightens wing loading. .

At any rate, saving weight is a good thing and worthwhile when it can be done. If you can save 1.5 lbs... I'd say that it is worth doing and will yield a reward of better performance and flight.
