Actually, like I said, if your use is limited, extra tankage can make a small compressor look like a large one, *if* you can trade time for capacity. Yet another tool in the kit. If you're running a factory on air power... you can't afford to wait. But, that doesn't describe most of us in T...

A couple of considerations! First, you can easily expand the storage capacity of your compressor by adding a portable air tank. I plumbed up my system so that it's easy to add or subtract a 5 gallon portable tank which about triples the capacity of the tank that comes with the compressor. You...

What language was this translated from? "The pilot and no one on the ground were injured." Paul

There are alternatives, I used to use one… but it’s been a while… Paul

Look at the amount of free play in the throttle shaft. I had a carburetor once before that went out of round there, and in certain throttle positions that created a vacuum leak along the throttle shaft…

Based on several experiences, the FSDO will inspect your plane from stem to stern, and cite many, many things they think need to be done better before further flight. They will then conclude there's no proof the static system guy did a bad thing, so he gets off. Complain to the FSDO only if...

Hi Todd, I think that's unfair... did you fill out the 337 and file the STC paperwork the first time you used Phillips 20-50 multi-weight oil? That's how it was initially introduced. The compliance percentage was uninspiring. I spent some time at the 94UL pump at Watsonville a couple months...

No one is proposing to do that now... three of the current formulations are based on high-octane ad hoc iso-octane, only one says they can aviation alkylate like we do in 100LL today. But neither iso-octane nor aviation alkylate move by pipeline today, so there's no synergy as you might be...

GAMA is the General Aviation Manufacturers' Association, a trade group of aircraft, engine, and accessory manufacturers. They haven't made any pronouncements on fuel cost. I think you're thinking of GAMI, General Aviation Modifications Inc, the guys with an STC for unleaded avgas. Only the...

Actually, the electronic ignitions aren't accounting for slower burn lean of peak either, as they don't know if you're rich of peak or lean of peak. They're taking advantage of the presence of less oxygen at altitude to infer that the engine will tolerate more advance without destructive...

Swift's original formulation smelled like sweaty socks, close enough! The current formula does not... :-) Paul

nah, you can water jet the line under the driveway... find a guy who has done it before. Paul

That’s odd… on the Cardinal, Monarch caps increase capacity a couple gallons per side.

The lead plant in Liverpool is under considerable environmental and economic pressure. There's a plume of adverse impacts downwind of the plant that have been well documented over the decades. The neighbors want it gone. The owner already went bankrupt once a few years back, and re-organized...

Thanks GT. That Paul Millner companion video is sure to be awesome! It’s not clear to me CAU will sell to transients as Bertorelli states… couple other points there need clarification as well. Paul

Hydrophilic − Refers to substances that absorb water. A hydrophilic substance will bond, on a molecular level with water. Hydrophobic − Refers to materials that will repel water. Oleophilic − Refers to a substance that absorb oils or nonpolar liquids. Oleophobic − Refers to a substance that...

Cars don't have the loose-tolerance air-cooled engines, with very large pistons, that we do... so the blowby, that creates the oil acidity problem, is an order of magnitude smaller... or maybe two orders? Paul

I think that would challenge the acid buffering of the oil... Reintroduction of aviation-tailored synthetic oil promises less engine wear and lower operating temperatures. I'll sign up for that! Paul

There are observers as well as movers and shakers of the passing scene who think that once we have two, three, or four (!) unleaded avgas formulations approved, there will be an industry effort to converge on a single, new ASTM unleaded avgas spec. That might well happen… the individual...

It can be; you need a re-refiner that is set up to handle it. Typically, the bottoms product from a re-refiner’s distillation column is sold to a refinery as coker feed; that little bit of lead doesn’t adversely affect petroleum coke properties, and there are hazardous materials exemptions for...
