One more thing CANADIANJOSH ,
You might want to try using CORROSION X on your radio gear .... it water-proofs the servos and Rx . Just open your servos like you have , then fill with corrison x , leave for about 5 to ten minutes to makes sure that its soaked in , then tip them over and drain over-night . Put your servos / Rx back together and wha-la .. water proofed .
