So something I do is just put a layer of clear packing tape down on the helmet first. Just a small piece slightly larger than the size of the GoPro mount. Then stick the mount to the tape. The packing tape is not going to peel off and the GoPro mount sticks to it super strong like it would stick to the helmet directly. The trick thing is that it is 1000% easier to peel up the packing tape to remove the GoPro mount than it is to pry up the GoPro mount if it were stuck to the helmet directly.
I’ve never had an issue with this setup even with the mount on my chin.
That said, I’ve never had an issue with having just the adhesive mount on my helmet in sanctioned races. The chin strap mounts work but they are fiddly and pretty heavy IMO.
I believe the “concern” of cameras attached to helmets is the idea that they may cause traumatic forces on the head and neck in the event of a crash. A GoPro mounted to his helmet is what some people attribute to be the cause of Michael Schumacher’s traumatic brain injury while skiing. I don’t know if there is any actual scientific research which substantiates this claim however. It is pretty weird to me that karting and auto racing has pretty much unilaterally banned helmet cams meanwhile they are ubiquitous across professional motocross, skiing, snowboarding, BMX, mountain biking, sky diving, etc. Basically all other action spots haha.
I have a friend that used to race MX and he had a top mount go pro. He unfortunately went
OTB and landed on his head. He is convinced this nearly killed him as it made his helmet a spear. Whereas a helmet only may have slid or at least deflected. With that said a chin mount like we use would avoid this. Unfortunately if insurance companies are behind the ban, no helmet mounts is a clearer directive. Does anyone know how European karters handle helmet cams?
At NTK, they do not allow helmet mounted cameras and at DKC they do. A lot of folks run both tracks and just leave the adhesive pad on their helmets when running NTK. It has never been brought up and when I am sitting on grid at NTK wearing a White helmet with Black GoPro pad right on top you would think if it was and issue they would say something.
