The overheads in my plane deliver a lot of air. With the side ones closed off it would also make your interior work easier. The only consideration might be that the air is blowing on or around the passengers head vs coming in from the side. But I really don't think that's big deal. If I were doing it over I might consider doing what you're thinking of. Wayne Edgerton N602WT Time: 11:02:34 AM PST US From: "Bob Leffler" Subject: Air vent question For those that installed an overhead console with air vents: What did you do with the standard rear seat vents? Are you happy with your decision? If you removed the vent and permanently close the opening or you left the vent per plans , any regrets in doing so? As you might surmise, I'm trying to decide what to do myself and am looking for other opinions and data points to help me make a decision. At the moment, I'm leaning towards removing the vent and permanently closing the opening. I think that the overhead vent will be able to deliver ample air via two new naca vents in the tailcone. I would also think this would minimize the chance for rain and other objects to come in through the vents.

I installed mine while I was still fitting the canopy and the forward tailcone skin was still off, but I can see how it could be done at any time by pulling the panels for the tailcone access.

I've had very little time over the last 18 months to make much progress, and due to work, it will probably be another 18-24 months before I can devote any significant time. Rather than continue to live with airplane parts filling in every room in the house until then, I'm putting the kit up for sale. I don't have any specific price in mind and I'm not in a rush, but anyone interested is welcome to come see it or look through my photo gallery of the build: http://noimnotcrazy.com/gallery/ It was a QB Fuse+Wing, kit #40715. I did pull the floors out for inspection, priming, and sound insulation, but otherwise is a stock build. Most pieces were akzo primed, much of the tail was also alodined. Tailcone is attached. The project is located in Southern California. Anyone interested or have questions, feel free to contact me off list.

Might not work for everyone but it's been working out great for me. Give it a shot and see if you find it good too. I don't generally get below 2300, and just use 2400-2500 for certain circumstances. I do find that although 25 squared isn't a bad way to climb, the engine stays cooler better for me if I keep it full forward all the way up through 5-7k' for climbing. It gets you out of the warm air faster. Tim Olson - RV-10 N104CD do not archive Deems Davis wrote: > > What engine setting are people using ? My oil consumption seems to have > stabilized.

Dear Listers, I've been pondering for a while how to "label" the various button functions of the Infinity stick grips I have wired up in the front and back of the RV-8. I spent some time today with the 'ol CAD program making a caricature drawing of the Infinity stick grip and buttons and adding some labeling. My plan is to silk screen the attached layout right to the instrument panel in the front, and to a small metal piece for the back. The cockpit and instrument panel will be black, so the diagram should pop nicely on that background. Just thought I'd pass on my efforts.

Best thing you can do to your engine, airframe, and instruments .... well, the steam gauge kind. Have the prop balanced at your chosen cruise RPM. You might play with the mixture again when you throttle back to see if it makes a difference with the vibration.

I understand the theory behind leaning while on the ground, but if the idle mixture has been set correctly leaning on the ground is not required (for 'standard' conditions). This is according to the folks at Airflow Performance. The manual provided with our fuel controller goes through this procedure. Leaning also does not explain the high fuel pressure......
