-# Finding the right glue
+====== Making the plane waterproof for landing in the water ======
+[[searchwing-waterproof-glue|searchwing-waterproof-glue]]
+===== Overview =====
+{{::waterproof_overview.jpg?400|}}
+These are the sections to close on the fuselage.
+===== Bulkhead to separate the motor =====
+{{::waterproof_bulkhead.jpg?400|}}
+{{::waterproof_bulkhead_2.jpg?400|}}
+===== Closing holes =====
+The so glued model had some holes to fill / close.
+I used thin plexi-glas. Best way to glue them was hot glue, as it can also fill little holes or 	irregularities in thickness.
+{{:waterproof_camera.jpg?400|}}
+I used the same technique also on other parts.
+====== Sealing connections and small holes ======
+Using a good tape can close all kind of connections and other small or thin holes. I used "3m Blenderm" - a waterproof and flexible tape:

+One other option is hot glue - as in this example:

+======== Waterproofing the servos ====
+there are 2 interesting articles on Instructables on this topic:
+https://www.instructables.com/id/Water-proofing-a-Servo/
+https://www.instructables.com/id/Waterproof-your-servo-motors/ (if you want to follow this one, dont forget the glitter on your finger nails)
+. Make the housing waterproof
+* I used "Curil", a standard sealing compound.
+* Open the servo and put the sealant an all touching surfaces
+* also put sealant to the cable, where it leads through the housing
+{{:servo_sealant.jpg?400|}}
+. Insert a O-Ring under the horn
+* remove the horn
+* add a 1mm thick o-ring
+* add some lubrication. I used "CRC Multilube" - attention - lubrication has to be compatible with the rubber of the sealant. Don't use silicon rings with silicon lubricant.
+* screw the horn back on

+===== Test it... =====
+- submerge in water while it moves
+- no bubbles should emerge
