Technical - Keeping the Electrics Dry


The RC Laser comes with a sealed area in the hull, in which the electrics are kept dry. Unfortunately, this set-up doesn't always do its job properly, leading to wet and damaged servos and receivers. By following the three simple steps outlined below you should have no more problems with water in your electrics. 


Step One: The Aerial Hole

The hole for the aerial is the most likely cause of water in the electrics compartment. The best thing to do with this hole is to remove the aerial from it and fill it up with candle wax, by holding a finger underneath the hole and dripping  in the wax (Fig. 1).










Step Two: Re-positioning the Aerial                 

The neatest way to reposition the aerial is to drill a small hole half way up the circular rim (Fig.2 - NB notice the first hole drilled mistakenly too far down) and then wrap the aerial around the outside of the rim. Once the aerial is wrapped around it can be held in place with electrician's tape (Fig.3); this will also help the lid to fit snugly into position. For extra security the lid can be taped in place whilst sailing, although I don't find this necessary.
















Step 3: Greasing the Servo Holes

The rudder and mainsheet servos are held in place by two white plastic arms underneath the deck (Fig.4) and a rubber block squeezing the servo in place from underneath (Fig.5). Remove the servo by swinging the arms forward and removing the block. Then apply a generous amount of synthetic grease on the top of the servo (Fig.6) before replacing the servo and refitting the arms and block.
