I mounted it on the step. You'll notice as the gear leg is getting bounced around the camera is not moving with it. I like the reference of the tire and gear leg. Prop kinda sucks, but oh well. Fun to play with that's for sure.

How many frames per second were you shooting? I've seen some video shot through the prop arc that doesn't stop the prop. I'm wondering what hardware is needed to avoid the video "prop stop."

30 frames per second. Which was pretty standard on the cams I looked at. I'm sure there are other ortions though.

There is a nice compact review of equipment options for recording video of your flights in the March 2010 edition of EAA Sport Aviation. The article also includes a short explanation of how to record audio. Well worth the read.

Cessna 182, Sony handycam, and 3-18" zipties. I'm sure glad I still have that camera. It was mounted on the gear leg, worked very well. I'm not impressed with that old camera anymore but it got the job done.

Very nice!!

Have any of you had the FAA types approve external mounted cameras? I always wondered about how legal it was to be doing this. Cables taped and tie wrapped, etc?? It is obvious where they are mounted when you watch the videos.

I use the Vholdr ContourHD 1080p. I mainly shoot in 720P because the field of view is wider. Here is a sample:

You can toggle HD on (720P) if you have a fast connection. It defaults to 480P.

I like the camera. It's mounted right behind the windshield.

Th prop arc from those cam's gives me a head-ake....

PG-
as long as you don't need "Tools" there is no approval needed..... I think..

You might look here for a solution to the prop strobe effect. I tried a Cokin plastic ND2 filter on my Kodak Zi8 and it didn't work, but maybe the ND 8 is the key (seems to be in this case)

Here is the video - impressive results

Has anyone tried one of these type cameras?

It would appear this camera would meet the criteria of shooting a minimum of 30 F.P.S. Not a bad price either.

Emflys: I too tried a filter, with a density of .6, upon reading it may be the solution for my cameras prop flicker, and it did not do anything, zero improvement. I first noticed the prop flicker with a pair of sunglasses I bought last year that have a built in video camera, at only $100.00 I figured what the hell. They were unusable in the airplane, so I bought the Sony, another $175.00, and again no good for flying video. I'm slowly getting educated at what seems to work! I want to get it right next time

Yeah, I am not certain on the ND filter. Zane posted a comment on Jerry's Vimeo site as to what is functionally happening, so maybe you really need the 8 stop filter. Not sure.

Essentially if you want to shoot through the prop and not have the strobe, you best bet is a real video camera, like that Canon VIXIA series, or similar. But they ain't $150! $500 yes.

I am still wrestling with my camera set up. I have the lipstick/bullet style which are small, and allow me to put anywhere, and remote stop/start. But, you really need good light, and limited to 480lines and 4:3 aspect ratio.

Probably my next purchase will be another true video camera for the pilots POV stuff, and a remote minicam for any other locations.

Well, get it all squared away before coming up here this summer! I'll try and do the same. Speaking of prop flicker, wouldn't you know that when I had a 55 minutes ridge soaring dead stick flight last summer, I had left the camera home!

Will do!

If the "shutter speed" remained the same w/ a ND8 filter the apparent intensity would have dropped off markedly; therefore, I have to assume the shutter speed became slower (exposure time became longer) to allow more light to the CCD and when that happened the prop movement became averaged out as it does with your eyes looking through the disk.

If you could control the f stop on the camera, going to a higher f stop with automatic exposure control would accomplish the same thing.

Hi everybody,

does any of you have experience with the "GoPro HD Hero", attached with the suction mount to the wing?

The result is generally good, however it looks like if the camera gets shaken by the wind!? I don't know exactly how he has attached the camera to the wing, though:

By the way - I know that cameras are quite often attached somewhere to the outside of the plane, but is this legal?


Cheers, Oliver

Exactly. The ND filter relies on the auto-exposure using a slower shutter speed to achieve the same amount of light exposure, after reducing the available light, blurring the prop to a point where the horizontal blinds effect is unnoticeable.

Most small camcorders are auto only, so this works fine. However, if you shoot with a camera capable of manual exposure or variant exposure modes, you can bump the F-stop value up and sort of achieve the same thing. You set a fixed aperture setting (higher, less light) and let the camera determine shutter speed. It will use slower shutter speed values, but vary them to avoid under or over exposure in a range that blurs the prop.

In bush Alaska, the pretty little Cessna with a handheld camcorder strapped to the gearleg draws much less attention than the C207(s) on the other end of the ramp with their tails firmly planted on the ground after taxiing in and parking, or the old private pilot without a current medical lifting his super cub off the ground using his Cat 966 to take the gear off and put it on floats, without the help of an A&P, and then having someone tow his airplane on a trailer down the runway to launch it with him at the controls, and buzzing his house at 100 agl before landing on the river

Shit...

Guess I'm guilty of most of those.

You must be talking about Bobby Mag .........he wouldn't do any of that stuff Fly By Night Air Air
