Builders: Our ‘ultimate’ evolution of starter systems is the 2400-L series. It was flight tested on the SPA/Panther early in 2015, and has since become the benchmark for simple, ultra-light, efficient and powerful starters for Corvairs. We have produced several hundred, and they are now our standard starter we recommend to every builder. . The great …

Builders : Below is a look at the Pietenpol project of the CC#32 local hosts Kevin Purtee and Shelley Tumino. It is about 85% done. It is an extensive update on their old Piet. The photos offer a good look at what the most current Corvair installation on a Piet looks like. . In the descriptions, …

Builders, Here is a look at a simple, but important part of the Corvair installations which require electric fuel pumps. Please note: While this part looks identical to the switch we used from 2003-2005, it has a critically different pressure rating, and no Corvair powered plane with electric fuel pumps should be flying with the …

Builders, Here is part 2: . “Boosted” engines: If normalizing is trying to maintain 29.92″ of sea level pressure in the intake, a boosted engine is driving the manifold pressure above this. This is actually very common, and almost every single classic radial engine was “Boosted”, except they most often used superchargers to do this. A …

Builders, At the bottom of this story is a commentary I wrote on human factors several years ago. It was prompted by an internet discussion where several builders were proposing complex arrangements for engine controls and questioning the value of the Nason switch we recommend for engines with electric fuel pumps. The recommendations we make …
Builders: I bring this up because it is the most common mistake I see in homebuilding, and oddly enough, it is about the easiest skill to posses, the tools are cheap, and there is no valid reason for doing this wrong……but 75% of the planes I look at have terrible wiring, particularly the terminal crimps. …
Builders, A friend of ours who is building a Zenith 750 wrote in with a quick note asking about oil pressure gauges and senders. I pulled together this general set of notes on oil pressure measurement and instruments as a good resource on the general subject. Over the years Corvairs have flown with just about every …

Builders, Here is a single location page that has a great number of links to information specific to the Zenith 750 / William Wynne-Corvair Combination. It is a particularly good match, we have a number of different ways to approach it that serve the needs of many different builders, and it is a success story …

Builders, Here is a single location page that has a great number of links to information specific to the Zenith 601/650 / William Wynne-Corvair Combination. It is a particularly good match, we have a number of different ways to approach it that serve the needs of many different builders, and it is a success story that …
Builders, Here is a single location page that has number of links to information specific to the Zenith 701 / William Wynne-Corvair Combination. In brief, we flew the combination in 2007, and it does work. Our test aircraft weighed 677 pounds ready to fly (without fuel) and more importantly, was well within the CG envelope for the …
