Quick tip, have no idea if anyone has already done this or not! For those of you that are worried when using the external mic with the Drift HD, you'll notice that the hatch you have to use is not water resistant... Easy fix, bead of silicon
To be honest mate, Ive had my poor drift out in some pretty crap weather and its been fine so far. just keep her clean and dry once your home.
I'd like to see that Jizzed on mess dry flat enough to form a secure seal. It'll be fine as it is TBH bar torrential downpours in which case I doubt anyone would be out on Track in any case.
That's why you build it up thicker than the gap left between the hatch and the camera...so when you screw the hatch down, it'll compress the silicon in to a Water resistant seal.. Does not have to be perfectly level if built up thick enough
