Many of those RC engines turn at over 10,000 RPM. That's 167 revs/sec. With a 3 blade prop that is each blade tip bluring half the rotation at 1,000 FPS as 500 blade tips pass any point in 1 second. You may want a large prop 4 stroke or a faster camera.

Though Tech, all of the RC planes I fly are electric ;)

If memory serves, this particular plane was running a ~7x6 2 blade prop on a ~1200kv brushless outrunner on a 3S LiPo pack... I could have filmed it in 1000fps and would probably have caught the prop, but the lighting was pretty bad at the time so I didn't bother.

I wonder how much deeper the ocean would be without sponges.
Right now I'm having amnesia and deja vu at the same time. I think I've forgotten this before.

I'm assuming this was 210 fps.
Was it an FC-100?

I tried that too. That one is about 6x slower than mine.

It's interesting, though not that hard to track the disks.

I enjoyed that video :)
It was a nice camera too! Cool how they can change frame rates while recording in HS.

That's not particularly hard. But my suspicion is that they don't. They probably record it at speed X, then play it back faster.

Much simpler, and allows you to change when you want the speed to change, rather than being signed up for exactly when you pressed the button in the field.

I suspect that unlike the Casios (which CAN change recording rate mid-recording), the cameras they're using probably can't. I think it's more likely that the whole thing was recorded in slow motion and then edited to speed up the bits they wanted in normal time.

And because my last reply didn't seem to go through... Yes my last vids were at 210fps on an EX-FC100.

Oh ok that makes sense.

The FS-10 can change from 30-210 fps but thats all. How about the FC-100? Can it change from say 210 to 420?

Nope, the FC-100 and the FS-10 are practically identical from a software perspective... It's just that the FS-10 doesn't have anti-shake, and the FC-100 can't autofocus during recording.

Cool. I ordered the FS-10. It should be here soon. I also got a tripod for shooting video.

I've been thinking about getting an FH100 but have now overdone the research and am getting too picky about small flaws. Plus I've been watching gopro footage, some of that 60fps 720p sometimes weirdly looks slower than 120 and 240fps, i guess its just the amount of detail per frame.


Does anyone have a high speed video of a spudgun's barrel flexing ?
And even better a high powered 10-22mm copper compressed air spudgun ? :)

Which flaws? I can give you my opinion on them, at least. (I don't know how many other FH100 owners we have here.)

That's one of the things I want to try. Unfortunately, no working launchers and bitterly cold weather preventing fixing them means that's off the menu right now.
