However, you really will not know if it causes a trim problem until you fly the airplane. The shape can be perfect to the eye but still require altering because of a "heavy wing". Initially my 6A flew hands off perfectly until I had the plane painted. After checking all the alignment points of both ailerons, the gear leg fairing etc., only thing I found was an impression on the top of the right aileron midway along the trailing edge. It looked like someone in the paint shop picked up the aileron by the trailing edge and put a slight dent/depression in the top skin right where a thump would have squeezed it. Following Van's procedure for correcting a heavy wing, http://www.vansaircraft.com/pdf/Wing_Heavy.pdf, I had to reduce the radius of the right aileron trailing edge and increase the radius of the left aileron trailing edge to get back to the 'hands off' trim I had before painting.

Cencula" wrote: > Although it's nice to know that it's still safe, I really need a > *solution*. Some alternatives: 1. Make a new rib for the worst location, drilling holes to match the skins. 2. Remove the clecoes from the worst rib, and drill new holes that match the skins in the spaces between each of the existing holes. When you get to painting, fill the unriveted holes and then paint over them. 3. (Van's suggestion) Drive the rivets as-is, and rig the plane to fly straight and true once you're done. Personally I wouldn't go looking for extra work, but if pushed i'd probably opt for option 1. -Rob ________________________________ Message 3 _____________________________________ Time: 06:40:12 AM PST US Subject: RV-List: NASA safety controversy From: "Bob Collins" (cross posted) You know how you're always saying you wish journalists weren't so stupid?

It's called Public Insight Journalism. We use it to evaluate potential stories and to be more informed before we even decide whether stories are worth doing. Today, I got a message from the unit.

Failing that jack stability is a must. Get two 2" or 3" x 3/8" national course bolts. cut off the heads. Remove the Van's tie down rings. screw in the headless bolts. If needed modify the jack stand by drilling a shallow hole (depression) to accept the headless bolts.

I put it at the low point in the back, behind the baggage compartment, extended the static line all the way to the bottom of fuselage. The line going from the bottle to the instruments is punched in to protrude an inch inside making it easy to keep any drops from moving forward. Putting that end of the bottle upward would do the same thing, but my connecter broke on that end of the bottle so I turned it into an opportunity. Bottle nipples are fragile. Since I live in South Florida with lots of humidity I also installed two 60 watt light bulbs (wired in series to reduce effective voltage per bulb) under the radio stack and plug them in to wall outlet in the hanger. This keeps the moisture out of my radios, the series wiring reduces the excessive heat a bulb would normally have in this confined area. Prior to this I was getting problems with my transponder after a humid week. No problems since.

If this is all you have to be worried about, then you are building a real fine RV. My RV has some cosmetic imperfections, dents, smiles, scratches whatever, now 5 years into flying, things that I thought were so important, I can not even find them, let alone allow it to bother me. This is sort of in the category of "who cares?" I would never have noticed without the straight edge in the picture. If you are building for flying, then move on, if you are building an Award Winner that will be exhibited in some technical museum, keep redoing it until it is perfect. If after flying the RV for a few years and it still bothers you, then rebuild it. But, by then you will be having way too much fun to worry about cosmetic accuracy.

Although it can select multiple actions it has no way of providing any speed control function on its own. Additionally, it does not provide any of the valuable features of Safety-Trim, such as the time limited servo drive, or simplified pilot/co-pilot wiring. -Bob Newman TCW Technolgies www.tcwtech.com Sent via BlackBerry by AT&T -----Original Message----- From: "Tom Young" To: Subject: Re: RV-List: New product annoucement I'd be interested to know if anyone has tried a two-speed setup using a 5-position inline switch like this (51MX down at the bottom): http://www.machinecomp.com/js_sa.htm First position, slow, push it a little farther, fast.

With the Safety-Trim two speed controller you only need a simple SPST switch to activate the two speeds. The switch just grounds the "two-speed input" wire or leaves it open. The safety-trim control box does the rest. The switch can easily be a simple manual switch on the instrument panel. -thanks, Bob Newman.

But now I do. And the answer is yes! It will work exactly as you described. One pole of the switch would drive the "two-speed switch input" and the other pole of the 51MX would drive the respective trim inputs. -Bob Newman Sent via BlackBerry by AT&T -----Original Message----- From: "Tom Young" To: Subject: Re: RV-List: New product annoucement Sure, I'm aware it can be done simply, I've just been interested in the possibility of a single-switch approach...
