Result in good normal consumption breakin. (O-320e2a) As an aside, I have gottien advice to only use 100LL, that use of Mogas is bad for breakin. However, I have not seen any compelling data re this. If it is due to the myth that LL suplies some lubrication, it is just that, a myth as I am told. As a mater of fact, I followed the advice of a friend who put 2 oz of Marvel Mystry oil in the gas at fillup. He had 2400+ on his O-360, untouched when he sold the plane.

Just to be totally clear about what I advocated in my post. I did not take a pilot up in an airplane unfamiliar to me and pull the mixture to a deadstick landing. I would not do that to another pilot in an airplane that was not my own, and I do not recommend that on a BFR. This is what I said, and what I did. Read carefully... "We pulled the mixture and flew best glide speed and the airplane came down 1000 fpm measured on my watch, not the VSI. The VSI showed about 800 fpm. We found that 1/3 flaps and idle thrust simulated that descent, then we practiced deadstick overhead 360 and 180 approaches to a specific point on the runway, without going short. He did well and I would suspect his chances of successfully making a deadstick landing increased dramatically."

Theoretically the ID of the pipe would be 1/8", but in reality, you are not likely to find a 1/8" pipe or fitting where the ID is exactly 1/8" or whatever the size it is called out as. Hear is a quote from page 2 of the www.mcmaster.com on line catalog. " Pipe size does not refer to the inside or outside diameters (ID or OD) of a pipe fitting or pipe. It's the accepted industry designation, not an actual size. When matching pipe OD for male threads and pipe ID for female threads, you need them to have the same pipe size." Their catalog has lots of good information on this and other things it's worth a look just for that kind of information. -- Chris W Gift Giving Made Easy Get the gifts you want & give the gifts they want http://thewishzone.com ________________________________ Message 7 _____________________________________ Time: 09:51:01 AM PST US From: wgill10@comcast.net Subject: RV-List: RV-7 fuel vent location (fuselage side penetration) 1.25 RCVD_NUMERIC_HELO Received: contains an IP address used for HELO --> RV-List message posted by: wgill10@comcast.net I am planning to install the fuel vent line prior to wing mating and cannot find a measurement for the location of the fuel vent bulkhead fitting where it penetrates the side of the fuselage.

Slider --> RV-List message posted by: "Bob 1" On the RV-6, there is a low pressure area along the side canopy skirts. This is because the fuselage begins to narrow about 1/2 way back along the skirts, and because that area also coincides with the low pressure area above the wing. Flow through ventilation is the problem - air is sucked into the cockpit through every other orifice in the airplane and exhausts around the side skirts. You can cut a piece of foam pipe insulation in half and place it between the slider tracks and the slider skirt to seal the area in flight. I carry a couple of pieces of this stuff with me during cool weather, and it makes a huge difference in the amount of cold air blowing through the cockpit. Adding more "exit" air ventilation would only make the problem worse. KB ========================================= I used 3M mylar door/window "V" strip to seal skirt leaks. Works better than anything else I've tried. P.S. Unless one understand which way the air is flowing.... chances are the direction of the "V" will need to be reversed.

Example: 1/2" plastic pipe. There are several different wall thickness' but the OD is the same. Next time your at Lowes, Home Depot etc. pick up any schedule 1/2" slip (glue) coupling and try it on sprinkler pipe, schedule 40 & schedule 80 pipe. You'll find that they all fit inside the coupling BUT they all have different wall thickness & therefore different "nominal" inside diameters. (same holds true for 1/2" copper in types "M" , "L" & "K" copper pipe). Tube is sized by OD which is why tube & pipe do not fit together without an adaptor. Pipe threads are tapered, tube threads are not. They are straight cut, no taper. This is the short lesson.

Best glide speed is a function of airframe performance, mainly the wings. Prop windmilling and prop stopped produce different drags and affect sink rate and gliding distance accordingly. Prop windmilling is higher drag than prop stopped. Another lister pointed out the drag difference to me by comparing a helicopter with rotor windmilling and one with rotor stopped. Which one do you think will come down faster? You have to translate the helicopter windmilling rotor producing lift instead of drag in this case but you get the idea. An autorotating (windmilling) helicopter can in fact land safely. I'll have to leave how much the drag difference is to the experts.

However, Bob N made the point that every connection is an extra point of failure. Since this area is exposed to the elements, you would need a weather proof connection. It's easier to just wire it without the connector. If you ever have to remove the wings, you can cut the wires and add the connector then.

But, the windmilling rpm should increase with airspeed, and the drag will increase with rpm. So, the windmilling drag should increase at something greater than airspeed squared. So, I would expect that the best glide speed with windmilling prop would be a bit slower than the best glide speed with prop stopped. But, the only way to know for sure is to do some flight testing. Once my RV-8 is flying, I plan to do a full series of glide performance vs speed with idle power, engine off and windmilling prop, and prop stopped. I'll publish the results once I have them. I am many months away from doing this.

At that altitude and weight, it was still climbing reasonably well, but I have never noted the climb rate. My plane has a cruise prop, and that limits rpm for climb at that altitude. At lighter weight, I've had it to 15,000', and was still climbing at 500 fpm. Van's site lists 17,400 and 21,500 feet as the ceiling for a 160 hp RV-6 at light and gross weight, and I think my experience shows that these altitudes are possible. Van's lists 25,700' as the ceiling for a lightly loaded 180 hp RV-6, which is fairly close to the 26,000+ achieved by Terry Jantzi. I guess those folks at Van's know what they are doing after all... ;-) KB ----- Original Message ----- From: "Charles Heathco" Subject: RV-List: How high have you flown an RV6? > --> RV-List message posted by: "Charles Heathco" > > I have been wanting to see how high my 6a would go before it quit flying > (sans oxy).

It's easy when you're building, and a pain when you have to cut the wires and install plugs later. Also, leave a little 'service loop' so you have room to work. MHO, of course!

So far no problems. Just make sure that you mount the plugs near the rear spar so that you can get your hand between the wing skin and fuselage.
