A big factor is also the Nr (rotor speed) of the helicopter. A Huey turns at 324rpm compared to an S61 which is down to 200rpm. Here's an example of getting decent (not great) blur on a S61 while the Chinook blade looks almost stopped.

You're also seeing the Chinook blade almost edge-on, which will make it look a lot less blurred than if you were viewing it at a broader angle.

Very intense.
This is a core image that well goes with narration, "A picture is worth a thousand words"

Good point. I think that's the real case in that picture.

A Gazelle making a speedy exit from Breighton Aerodrome reasonably sharpish for 1/40s.

Apaches seem popular...

Had a visiting helicopter the other day that approached into the setting sun.

Very clean shot considering the amount of prop blurr you have. Care to share the EXIF?
Thanks

I checked the file and found the following info.
shot at 400mm
1/50 sec.
ISO 100
I was using a EF-100-400L

Also wanted to post this one.

Attempting to shoot choppers reminded me how difficult sharp shots are at low shutter speeds.
Please excuse the f/29, it was a bit rushed flicking down to 1/30 in Tv in bright sunshine on the first shot. One perk to the hard sun was the sharp shadow on the tail rotor.
