| The hole is 6mm wide. Don't try drilling it all at once with a 6mm drill bit or you may end up ripping the plastic. Use a series of smaller drill bits to get to the final size. A little tube will be glued to the hole parallel to the groove so drill the hole with that angle in mind. |  |
| The first thing to do is to drill out the necessary holes in the hull. The drive shaft and dive plane holes are already drilled so that leaves only the rudder linkage. |  |
| If you have the optional light kit, you will need to drill a hole for the spot light. The light kit was no longer available at the time of this build so I decided to make my own. |  |
| To build my spotlight, I used parts from a small flashlight and a LED dash replacement bulb. Even though the LED is designed for 12 volts it works just fine on 6 volts. The front lens was super glued onto the bulb housing of the flashlight. The dash bulb was glued using silicon adhesive. The assembly is watertight. |  |
| Once fitted into the hull, I used Stabilit Express to glue it into the hull. The spotlight is extremely focused, I could of moved the bulb closer to the lens to get a wider pattern but I light the tight spot light. |  |
| The hatch opening needs to be slightly clearanced for the drive gears |  |
| A fin is glued to the bottom of the hull using stabilit express. There is no slot or anything other then glue to reinforce the joint. |  |
| I lightly superglued the fin in place first to get it in the correct position before applying the stabilit express. |  |
| The next step is to glue in the component mounting rails. Be careful to mount them 51mm apart from one another so the brackets will fit. With the rails pushed against the side of the hull, one end is at the right distance but the other is to far apart. |  |
| The next step it to glue the tail fin on. |  |
| The rudder is then fitted and held on with a pair of screws. I like the design of this boat because almost everything is easily removable. |  |
