Very nice thanks. ps
Yes Very good. Since we now have a 9 Cyl. Radial attached to our SNJ-4 it was helpful in how the dang thing takes gasoline and turns it into noise.

That demonstration really makes my 2 stroke outboard look simple.
Pretty interesting to watch. That guy really has a way with machining wood.

I was pondering how intelligent that guy is, and then began to ask myself how smart were the folks who designed such a system with pencils and slide rules?
That guy is a great instructor, not to mention what a wizard at being able to build that model!
Our forefathers were amazing!

Yep The P&W 1340 in our SNJ-4 first ran in 1925. It was the first eng. designed by Pratt.

We sent men to the moon with those tools.

boggles my brain to even think that there are folks who can come up with this kind of stuff.

And now SADLY, we got kids that can't even make change without a calculator or cash register and that get GOOD GRADES for getting the wrong answer through some stupid convoluted math process.

By the way; BE SURE to WATCH ALL THREE episodes ; Really great.
I grew up on US NAVY air stations and use to hear those engines starting up all the time, especially when I'd visit the Hangers selling Newspapers. Especially the on the base South of Jacksonville, FL .
We lived in the Navy Housing at Yukon, FL. (it's ALL gone now).

Yea but remember we had to send Men to the Moon before we figured how to put wheels on luggage

One of my favorite sounds was the P&W 985 starting up in our CAP DeHavilland Beaver firing up. We didn't have a hangar for her so she sat outside at the Kotzebue, AK FAA station. Starting up a big (to us) radial outside in -40F temperatures was a real drill that required at least two men and a Herman Nelson heater. It wasn't a quick operation, took nearly an hour from beginning to smoothly idling engine. That didn't count the time spent cleaning frost off the wings and tail, and other preflight chores. But that cough, fart, and throat clearing that engine made getting under way was a prediction for my old age. I now do the same getting underway. I don't sound so pretty as that P&W though.
