I feel the standard attachment method is flawed, at least for me. The reason is, I have always taxied airplanes with the door ajar for extra ventilation, especially here in Las Vegas. When I tried to open the door while taxing the Vans RV10 during a demonstration ride many years ago, I was chastised for it because the demo pilot warned me the doors are "weak link". A forward hinged door, like on a Cessna, will take the prop-blast in stride, and the blast will try to move the door in the direction it wants to go. A top hinged door when hit with a prop-blast or gust of wind, will try to open the door, as the in-flight RV10 door failures would indicate.(none of unlatched doors tried to slam shut, that I've heard of). I have a secure strap attachment nutplate, reinforced with an aluminum plate, glassed inside the door halves, to allow me a nylon strap to hang onto while the door is partially open, during taxi.The hinges are being reinforced with an aluminum plate on the outside of the doors, thru which the countersunk screws will pass. The plate is approximately the same size as the indentations (pockets) in the inside of the door, where the hinges mounts. The inside plate, also the same size as the tapered down portion of the pocket, has nutplates mounted for the screws. The hinge is embedded in epoxy/cabosil, that was set with mold release, so the hinge can slide in and out of this channel, for removal. The inside plate is then covered with carbon fiber, up the sides of the hinge pockets,and epoxied on. The remaining depth of the pockets are then filled with micro, so the pockets are now flush with the doors. The result is a significantly stronger hinge attachment, that should survive my desire to abuse my doors while taxing. Who knows, it may be strong enough to survive an in-flight opening?

I have a work trip flying out to Modesto on the 13th and leaving on the 15th so I have the afternoon/evening on the 13th and all day on the 14th. If not does anyone know a good hotel to stay at? I may go to Yosemite.

It's probably amazing this time of year with school back in session, much less crowded but still terrific weather. Of course the Ahwahnee is the most notable (AKA Pricy) place to stay in Yosemite but also the Wawona Hotel is a very nice setting. Bring your hiking boots, backpack, water jug, camera and enjoy. http://www.yosemitepark.com/accommodations.aspx Robin Do Not Archive -----Original Message----- From: owner-rv10-list-server@matronics.com [mailto:owner-rv10-list-server@matronics.com] On Behalf Of Strasnuts Sent: Monday, October 11, 2010 9:29 AM Subject: RV10-List: Oct 14th help - mid california Wondering if any builders out there around Modesto within 2 hours need help with a build or want distractions from a fellow builder.

I don't like the big wedge cutout ..... this is for trim, not flying the airplane!!! One advantage I have is that I can program a single-chip (almost) computer to control the servo.

I'm not looking for 12V servos. They're all too big and heavy, and they don't normally go to a set position. The 'zero' of the model servos can be set by length of the pushrod or by programming. Plan 1 is to use a programmable processor (Stamp Computer) to create the pulse and drive the servo. Power for the processor can be a simple 7805 or a converter that plugs into a car. I've already written the program to drive one servo, and it's easy to port to two servos. One neat thing the program does is center the trim on power-up. Plan 2 is to use my MGL panel to drive the servo. MGL has said that using similar programming thatg the PWM autopilot does can be used for the PWM trim, and they have put it on the list of improvements. I like the small size of the model servo and ease of installation. They'll mount on the bottom rib of the rudder and outboard rib of the aileron.
