GPS? A
Sound Speed App? I admit to not knowing the limitations of them so they may not track those speeds. Yes posting vid of a plane traveling definitively more the 100+mph seems to be a violation according the Current FAA 14 CFR
Part 107 rules. (see section highlighted in black)

In a interest of being good Stewarts of the hobby, many will not be on board.
Forces from Air speed are (0.00256)(V^2) Velocity V is in mph.
60 mph = 9 psf, 100mph = 25.6, 150 mph = 57.9 psf, 200 mph = 102 psf
3x speed = 6x forces on the plane. (let alone turning g-force loads)
an exciting challenge.
