Short Run Video; Panther.

Builders;

Below is a short video of Paul Salter’s Panther running in front of his hangar.

The first think that sharp eyes will notice is that the engine has it’s cooling baffles in place, but it doesn’t have a scoop to force the air through the engine.  I tell people to never, ever to run engines like this, and if you look at pictures from our colleges, every single engine has the green cooling shroud in place.

.

Here is the critical difference: This isn’t a “New” engine. It is the same 3,000 cc/ 120 HP Corvair that flew in prototype Panther for about 200 hours. ( The prototype has been upgraded to a 3.3 liter Corvair.) Unlike a brand new engine, it is OK to run this engine for short 30-60 second runs at low power without the cooling baffle.  The reason why this is never done on a new engine is because lots of short start and stop runs are murder on a new cam. On a new engine, you ideally want to start it once, and run it without stopping at all for 20-25 minutes at 1800 – 2200 rpm. After that, the cam is set to go and the engine can be run for short runs without issue.

.

The purpose of running the engine in the video was to verify wiring connections and system on the plane. Other people might not like this type of a video because it is a “bad example”, but I trust our builders to be intelligent people who understand differences between new and broken in engines when it is explained.  I don’t like being treated as a kindergarten student,  and I don’t treat people that way either.

Paul’s Panther

Builders,

Below two pictures of Paul Salter’s Panther. Paul lives in Jacksonville, and is a Park’s University trained Aerospace Engineer for the US Navy, working on the EA-6B Prowler program. A number of years ago he built a large hangar at the same airpark where Dan and Rachel Weseman and Grace and I live. Working on weekends, Paul has built a very nice 3,000cc Corvair powered Panther, which is now in the very last stages of construction. Today, Paul was working on the weight and balance data.

Paul’s plane was displayed this year in front of our booth at Oshkosh. Because Panthers have quick folding wings, it was very easy to transport to the airshow. While the plane was nearly complete then, Paul isn’t in a competition with anyone, he built the plane at his own pace to satisfy himself, and did not loose sight of his personal level of excellence nor his sense of fun. The plane is equipped with an Elison EFS-3A carb and a Sensenich prop. It had a number of details like a full glass cockpit and an autopilot. Yes, Paul is restoring an observatory. Some people take astronomy very seriously.

Above is a shot of the Panther airbrushed on each side of the plane’s vertical fin.  If you look really closely, you can see clever planning on the artist’s part: Notice how the eyeball of the panther is actually a structural rivet head on the plane.
