1. Breaker points no wonder those engines took so long to start

2. Amazing back in the early 1900’s we had no idea how to make a powerful reliable engine even for a car then by the 30’s-40’s we were making absolute amazing engines like this! There are so many moving parts on these engines it’s amazing we were able to build
   So many of them so fast for the war effort

3. imagine cleaning this monster

4. Pure engineering.

5. All the mechanics were also trained as watchmakers in Switzerland

6. Awesome. Can't wait to forward this video to a friend of mine who was a crew chief in Air Force. He will love this.

7. Aw, man! I thought from the title you had one and was wrenchin' on it!

8. how many moving parts.the sleepless nights Curtis must of had

9. Interesting how the jugs are mounted in a semi spiral layout! I wouldn't want to be the one to install and align all those gears (got to be more than a hundred). Thanks for sharing.

10. the amount of engineering that took to make, and they didn't even have calculators back then.  

11. a marvel of engineering

12. My late father used to fly the C124 Globemaster II that was powered by four of these monsters. They were huge aircraft. 

13. a lot of napkins and a lot of alcohol to come up with that design.  

14. That thing is beautiful

15. Pretty impressive that someone took the time to do a cross section for the display AND someone to do a video of it :>)

16. We used to work with Pratt and Whitney at Kearfott if you recall.  You probably would enjoy some of the airplane museums in Pensacola, Virginia etc.

17. That was a cool video

18. I will take one do you deliver?

19. Now that's just way cool! Where is that at?

20. Now you know why radial aircraft engines fell out of favour in the '50's.  Too many moving parts and not enough grunt for the money.  Not much fun changing 56 spark plugs out in the weather.

21. that's  cool. wicked  video

22. So will that be going in the single cab?

23. A very cool engine. 🙂

24. wow how cool is that

25. Very nice!!

26. Thats a cracking display :-))

27. Now that's neat!

28. nice!

29. This is really neat.

30. Interesting. i like the little light that come on during the time it was to spark. 

31. thanks

32. I always enjoyed those engine cutouts. Really fascinating to watch.

33. R4360 wasp major. Had one of these cutnaways at A&P school. There is a very interesting book about this engine.

34. The P&W Wasp engine(all 4360 cubic inches,4300 hp worth) was the final radial engine P&W made…That cutout engine is but one of several,all devoted to the instruction concerning the  internals of the radial combustion engine P&W produced…

35. Very cool thanks for sharing 

36. Awesome vid.

37. Pretty neat!

38. I was an Aviation Machinist Mate in the navy. I worked on P2V Neptunes that were powered by two Wright 3350 cubic inch stacked 18 cylinder engines, 9 cylinders per row. They had 3 turbo chargers and put out 3350 horsepower.
