Great demo and full marks to the maker for coming up with a design for what could be a sizeable niche market. I do wonder how long the propshafts and gimbal will stay waterproof though.
This is kind of interesting actually. For kicks n' giggles my son and I bought one of those Amazon waterproof drone knock-offs on Amazon. We dunked on the pool, on the lake and it survived. I wonder if... As mentioned @YuKay I too want to know the duration of the gimbal as well as the whole unit holds up being dunked repeatedly.
I love those type of flight reviews, where the reviewers are unscripted and just there to have fun.
