It reminded me of my own love and memories of beloved old dogs and other departed family long gone to rest. Thanks for sharing.

From: "taildrags" Jake; the difference in weight between your left and right elevators is probably due to the trim tab, bellcrank, and electric trim actuator servo on one of them. You do have electric pitch trim on your airplane, coupled to the altitude hold autopilot, right? (Just kidding) With that weight difference, it would almost make you wonder if the same wood species was used for the two pieces or something. -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power Read this topic online here: http://forums.matronics.com/viewtopic.php?p=408628#408628 ________________________________ Message 3 _____________________________________ Time: 01:58:45 PM PST US Subject: Pietenpol-List: Re: tailplane weights...

From: Ken Bickers For another data point (or points). Here are the weights of my tail parts. These are covered and painted. I used Stewart Systems with the lightweight (uncertified) ceconite, Stewart primer and Benjamin Moore's Advance for color using the techniques in Malcolm Morrison's slides (thanks, Malcolm). Control horns and hinges are installed and included in these measurements: Vert. Stab 2 lbs 2.2 oz. Rudder 4 lbs 0.4 oz. Hor. Stab 7 lbs 10.6 oz. Elev. 3 lbs 10.6 oz. Elev. 3 lbs 9.8 oz. Here are some other weights: Aileron 5 lbs 11.8 oz. (includes horn, but excludes piano hinge and hardware) Aileron 5 lbs 6.2 oz. (includes horn, but excludes piano hinge and hardware) Flop section 4 lbs 13.8 oz. Jury struts (vertical pieces are 3/4" thin wall Chromoly round tube with balsa to streamline, covered with fabric; horizontal pieces are 3/4" thin wall Chromoly with crimped ends) 1 lb. 12.1 oz, each side. I haven't yet weighed the center section (which includes an 11 gallon fuel tank), the diagonal struts (like the jury struts, streamlined with balsa and covered with fabric), or the wings, which are now covered and painted. I'll try to weigh those soon.

From: danhelsper@aol.com Here's a head scratcher. When weighing my plane NX929DH right before inspec tion for flight, left wheel weighed 358 lbs. while the right weighed 339 lb s. That's quite a difference I would say. What's on that side that is so he avy? Subtleties in the Ford? At the time I had the side-driven mag on that side, but that doesn't account for all that weight.Never really figured it out.

"There sure are a lot of sharp edged with the aluminum. What happens if you crash?" Granted he is a nervious nellie who is scared to eat at mom and pop mexican cafes and will not go point into a windowless bar. BUT does he have a point. As I am putting this back togather, I know that I will cover the edges with foam and real simulated leatherette. But the sharp edges could cut straight through that if I planted my face against it at, Oh lets say 50 MPH! I have since thought of adding some small hard plastic trim to it. Any other thoughts?
