I made a second, much longer drive at dusk and this time I was careful to stay away from the water. Still the sand stuck to everything and I had to take it apart again to wash it off with the hose since I didn't have an air compressor available. I don't think a compressor would have made much of a difference though because that fine sand stuck to everything like glue. I took my long-range antenna with me but I didn't even use it since I could go plenty far with the 500mw 2.4GHz Tx and Fat Sharks Rx with just the omni antennas. I was up on the second floor balcony of the beach house and had LOS the whole time so that is probably why.
