I landed in the sand on a beach (straight up standard landing, no flipping) and am afraid if sand got in the motor or gimbal of my Phantom 3 Pro. There was a lot of sand on the legs and a bit stuck to the rubber ball vibration absorbers at the top of the gimbal so sand got at least that high. Would there be any symptoms it would show? I've flown several times after and no difference in flying function. I am going to hand catch at beach from now on. Thanks.
