Magneto ignition. > > >Gerry Conrad > >C-GCUN > >RV-6A, 25 hrs > Gerry, Your question is far too broad, even if you gave more specifics. Fuel burn is not magic. It is function on how much horsepower you are using and how rich/lean the mixture. There is a rule of thumb that can be stated in many ways. One is ... 12 horsepower per gallon per hour. On this basis wide open throttle [WOT] at sea level will produce the rated 160 horsepower at 2700 RPM. This would be a MINIMUM of approx 13.3 gallons per hour. If you reduced throttle to 50% power or 80 horsepower, it would be approximately a MINIMUM of 6.66 GPH. To know what horsepower you are actually using can be elusive. Check the Lycoming charts for the horsepower produced at various combinations of altitude, RPM's and manifold pressures. If you don't have a manifold pressure gauge, you are out of luck and will have to resort to some assumptions and guessing. BTW... the above figures assume you are leaning appropriately. Consumption figures will be higher, if you are running richer or leaner than necessary. BTW... leaning your Lycoming is a whole 'nuther LONG chapter and a subject of much controversy.

My pins got easier to put in after a few hours and have worked very well since. I ground a long taper on the end of the pins,very slightly curved in the proper direction for the side it is used on. I ALWAYS rub "Boelube" on them before inserting. The Boelube is the answer,probably. Bob Olds RV-4 , N1191X A&P , EAA Tech.

I have my top cowl attached at the firewall with simple screws. I have had no problems so far, other than having to replace a platenut occasionally. I would recommend the plate nuts with the floating nut to allow for some misalignment when trying to get the cowl back on. The only problem that I can see is the cowl is a bit wavy, with the low spots being where the screws are. I would think that some kind of fastener like zsus would work fine as well and be quicker getting the cowl on and off. I also eliminated the short piece of piano hinge on either side of the cowl just behind the prop. No cracking or any signs of stress so far. If you have some time off this summer, Don't forget the COPA convention is here in Fredericton.

How did it go? Did you get cracks later on or any problems whatsoever?? Eventough I've removed the top cowling close to fifty times so far I never had any problems but lately it has been a major pain in the back to get these pins thru. I have realigned the hinges as best as I could but I still have troubles getting the top pins thru. Now I'm starting to look at better options. Anyone with a web site or pictures I can look at will be appreciated.

They are very nice fasteners, they have adjustable depth, sit flush, work excellent, but they are kind of big and they don't look as nice as they are more pronounced and are much more visible (I had flush screws there, but they were chipping the paint and were a pain to unscrew). I can now get my upper cowl off in about 3 minutes, verses 10 or more before. I sacrificed a small appearance downgrade for ease of removal. -Mike Kraus N223RV RV-4 Flying N213RV RV-10 Empennage ________________________________ Message 9 _____________________________________ Time: 07:10:30 AM PST US From: N223RV@aol.com Subject: Re: RV-List: Fuel Burn 0-320 --> RV-List message posted by: N223RV@aol.com I have an O-320, 160 hp, typically fly around 6500-8500 ft, 75% power (2450 rpm assuming my tach is correct) and depending on how I lean I get from 7.5-8.5 gph.

Gerry Conrad C-GCUN RV-6A, 25 hrs Hi Gerry On my RV-6A with carbureted 160HP 0-320, Sensenich metal 79" pitch. I flight plan a cruise fuel flow of 8.3 US gal/hr for x-country @ 65% - 70% power, no fancy equipment so I normally lean to peak power on tachometer, I plan 11.5 GPH for climb. Flight plan speed is 145 knots. In local flying & short X-country's I am averaging 7.7 to 8.3 GPH overall burn. So don't keep us in suspense, how much fuel did you have left??

Clark" Subject: RE: RV-List: electroaiir ei miss --> RV-List message posted by: "James E. Clark" Gary, I get a " ... cannot be completed as dialled ..." for the number given. Might want to double check to see if a digit is off. First, I would give Jeff Rose a call. He is VERY helpful. Three things to check: 1. Plugs Seems you are using auto plugs. If so, they may have reached the end of their service life. As you probably know, Jeff has found that the REM37BYs work better. That doesn't help you at the moment so hopefully a new set will do the trick. And they are cheap so a quick run to Auto Zone might get you back smooth. 2. Wires Any chance a wire has rubbed against something and has arcing going on? We saw some chaffing on one of our wires and was able to catch it before it was too late. Jeff says his system has either 65,000 or 85,000 (I **think**) volts being spewed forth so if there is a way for electron-type things to "escape" before the plug they will. Since you are using automotive then to attachment to the plug is probably OK. If it were the REM37BYs then I would say make **sure** it did not slip out a bit. Maybe even a little RTV to make sure would have been in order. 3. Pickup Have you been able to make sure the pickup is not just a little bit loose? Do you have the directions with you to tell if the timing is right? If need be, a trip to the airport could be made. But by the time you get this, you probably will have called Jeff Rose ... which is what I would do first order of business. When I was trying to chase don a problem, Jeff was there "with me" every step of the way (even though it turned out to NOT be his system as the culprit). He was paitent and helpful ... even on WEEKENDS! I'd give him a call. But if there is anything we can do "shoreside" to help, give a call ...

Various experts (including Bob N. at ) recommended RG-400 because of it's stranded center conductor, small bend radius, teflon insulation, and plated copper shield. However local and on-line sources wanted $1.75/foot and additional dollars for the connectors and attachment tool. I finally found a source who had unused 15' RG-400 cables with male BNC connectors and molded strain reliefs on each end. Unfortunately they had to be purchased in bulk and I now have more than I need. If you would be interested buying one or two, pictures are posted at . They are $18/cable (plus $5 dollars for shipping via US mail to a US address and $1 for each additional cable shipped to the same address).

When you buy the vents from Vans you get a paper template for the size and shape of the hole to cut. Not sure if this will work when upgrading an existing plane, but a cunning trick I found out AFTER I'd cut my holes is to install the vents in line with the cowl hinge line. The hinge pins can then be installed from the rear (and can't slip out into your prop).
