Just tried out the new motorsport mounts for the Hero camera

Its really pretty good. you can do roof mount, hood mount, rear hatch mount or even a contorted rear suspension mount, along with "front rotor" mount from on the fender.

Interesting, there is no real vibration moving it around and the sound is good.

very cool!!

That looks very similar to the mount I got from Wood's Power Grip. Just make sure you have a safety strap on there. I found it can come off if you're not carefull.

this doesnt require a safety strap. it has a push button that compresses the suction, and then a pull clamp for additional clamping leverage. It aint coming off, its tough to come off when the thing has been released!

I did some mountain driving and some high speed freeway video, just to see how the sound is now. very nice!

Can you youtube an example video?

Carl Young had an interesting story about those suction cup camera mounts. They were going
to do a film with his car, so the camera car had one of those mounted on the trunk. He was
suppose to follow the camera car for this segment, and as they hit 140 mph the mount broke
loose and the camera and mount just barely missed Carl's Twin Turbo, narrowly avoiding some
major damage...

There are some more robust suction-cup mounts. I agree with MK that the Woods cups are the best for the duty, but I'd be a lot more comfortable with two or more cups and a safety strap that others recommend. This suction cup has its own little pump with a spring that preloads the suction. It's about as secure as a suction cup can be. The fault in external mounting is you can't see the telltale that shows when there's a leak and vacuum is being lost. A single cup means that there's a lot of overturning force on just that one cup. It's trying to lift just an edge when the wind is pushing hard on the camera and bracket. There's a three-cup bracket that's much safer, and they also have some with 6" cups for some serious camera applications.

you cant break this suction free. Its already being used on race cars around the world without safety straps. the forces are not that great at 140mph as to cause concern. this is the kind of suction cup that can pull dents out of fenders! its very strong. you cant break it free. You will break the plastic well before you pull off the suction . actually the more force acting on the suction, the greater the suction force is. Now, to bob's point, if the seal has some leakage, the vacuum could be compromised. on a paintd surface that is very unlikely, especially for the 30min that it is being used. the forces are not that great either. in clean air, near .4psi at 160mph. at 4 sq-in surface area, thats only arond 2lbs of force. I can lift the rear deck up with this suction very easily for 30min.

Here is the video. it probably wont get up and running until 9pm PST, but it not only shows the flexibility in the mounting of the GoPro, it shows the clarity. I finally figured out how to get better edited quality with Windows media maker.
its at near 2Mb/second rather than the 500Kb/second the other videos were made from on the VIMEO video site. (and who knows how much less than that YOUTUBE decimates it down to )

Mark, any idea why I have no sound viewing my Go Pro video on a computer, but sound is fine if I view it on a TV?

mark kibort

Let me guess, you have Vista? for some reason, microsoft hasnt fixed that yet. dont hold your breath. on an XP machine, you can put it in Windows media maker and then put the file back on the vista machine.

Pull up the file with Quicktime and the sound should be there.

Thanks, a PITA but at least there's a solution.

iirc, PCA won't allow suction cups for stuff. is there an exception for these?

mark kibort

Im sure there will be once they see the mounts effectiveness. as Bob mentioned, this is not the same ole' suction cup that you see, plus the camera is very very light. To answer your question, i dont know. However, there is a fix. in the kit, there are the 3M pads that fit the assembly with a clip. This is very secure and will pass . you can use these on the inside of the rear window as a perminant mount, or on the outside where i have the suction cup. (or outside on the glass on the rear of the car)
