Subject: Pietenpol-List: Red Face CorkyPieters,Is my face red. I've repeatedly reminded the list as to what a real dumbass I am. Well, I proved it by anouncing those W & B results of those bathroom scales from yesterday. WIPE OUT ALL THE WEIGHT INFO I'VE GIVEN YOU. IT'S WRONG. ERASE THE BOARD.This morning a friend knew a friend who had the real digital aircraft certified scales. He came over with them, as he will not let them out of his sight, weighed NX41CC and now I have the official figures. (Edwin it was Steve Culp)L Wheel 301R Wheel 306T Wheel 20From leading edge vertical drop (datum) back to main axle center is 7 inches.From main axle center to tail wheel axle center is 167.5 inches.Would one of you in the W&B know how please figure this and post it on the list for me. This is empty, no fuel or oil.Corky in La with a red face________________________________________________________________________________

Corky,I just want to make sure this is the whole aircraft, wings and tail surfacesand all that stuff..AS it will be when ready to fly.No fuel? No oil?As the man said.... It is a good idea to put you in it on another wiegh in.That way we can compute the exact position of the pilot seat. Then put somepoor soul in the front cockpit and weigh it one more time for the exactpostion of the front cockpit seat. No wiggling or farting so as to put anerror into the calculations.chris bobka-----Original Message-----

You don't care what the distance from the mains to the tailwheel is, justfrom the datum to the tailwheel.Using the numbers you give, here is the CG: weight arm momentmains 607 7 4249tail 20 174.5 3490aircraft 627 7739Therefore the CG is the total moment divided by the total weight (7739/627),or 12.34 inches aft of your datum. In my earlier response to you, I thoughtyour mains were ahead of the datum, there was the rub.Gene________________________________________________________________________________

I have no idea how the CG should be for an empty Piet, maybe someone elsedoes. I agree with all of those who say that you need to figure with apilot and fuel, though. I would do it with a real person (and with two) andfuel, because I am not sure how exact the locations would be for the CG ofthe seats and fuel tank. Best to know exactly what you have.Gene________________________________________________________________________________Date: Tue, 6 Aug 2002 09:33:29 -0700 (PDT)
