Speed rating for GoPro suction cup mount?
« on: May 22, 2019, 12:13:30 PM »
I know a lot of GoPro cameras are used on LSR cars.  So has anyone had a problem with the suction cup mount coming off at speed?  How fast can you go and not worry that the camera will tumble down the course?  I expect to reach 200+ mph and I don't want to be dropping GoPros on the course.  I have never seen this subject addressed.

Somebody really needs to make a smaller aerodynamic camera like the ones that Replay used to make.
Go pros are so freaking big.

No rule against it but all the camera mounts I've seen at El Mirage & Bonneville are clamp mounts.
Let's think about this. If it did fall off, and a 400 mph streamliner ran behind you, hit it, failed a tire and crashed. I wouldn't want that on my chest.
The SCTA has enough problems with Dzus buttons that fall out and cause issues.
Just my thoughts.

I agree, someone would need to calculate the aero loads put on that camera and simulate it plus safety margin to be sure it does not come off during a run. It is a serious issue.

I have watched lots of YouTube videos showing GoPro's using the suction cups.  First time I saw that I wondered how safe that could be.  Looks like GoPro says they are good to 150 mph.  I am going to play it safe an go with a rigid mount but I wanted to see what experience others have had.

Smart move, Paul.

There is one advantage to the suction cup mount in that they do help minimize vibration, but I'm certain you should be able to come up with some isolation technique, if vibration is an issue.

A friend of mine using Rasberry Pie (RP) electronics, showed me a neat little camera that plugs into a RP board. This camera is about the size of an old half dollar coin with decent resolution. Not very expensive either. I plan on having two mounted on my car, one in front and one in back. The one in front will be under the canopy. Mostly, I want to see how the car is handling. Sometimes, the driver says one thing and the camera something different.

As a guy that has run lots and lots of Go Pros on land speed vehicles, (from door slammers to streamliners) I can tell you what I have done.  I have used the suction mount and then I have ALWAYS run strips of gaff tape along the base to secure it to the vehicle.  It had worked extremely well!!

What ever you do go to GREAT lengths and then 'over do it' to ensure that the camera is secured!!!!

Don't be the knuckle head who drops their camera and causes and incident on the race track.  There's absolutely no reason for a camera to fall off a vehicle.

At BMST you have to have a leash to attach the camera to the bike as backup to whatever mount you use. Cheap insurance. Rookies are told the most common debris to shut down the course is GoPros. FWIW I used a GoPro on a handlebar mounted ball mount and a Samsung Gear 360 on fixed a handlebar clamp mount last year. The brick shaped GoPro tipped back the ball mount and lost the shot at about 70mph. The more aero Gear360 worked just fine all the way up to the screaming 90 mph I hit and it will be the camera I use this year.

Wow.  I am surprised the suction cup holds at that speed.
