1. Adjust silicone rings ("SR" for short) positions on jib boom as shown.
2. Use forestay cord on the bottom left corner of jib sail to tie a loop, then loop around jib weight shaft. Cut a length of Dyneema cord at around 100mm, attach it to eyelet in bottom left corner of jib sail,the other end of cord thread through eyelet in jib boom front end fitting from back side to front side Pull cord to make sure jib sail is 3mm-5mm top above jib boom, then attach cord to silicone ring "SR1" on jib boom. Adjust SR1 position to adjust jib sail distance from jim boom.
3. Use metal sail crew ring between SR5 and SR 6,to hook the eyelet on bottom right corner of mainsail,the two rings are used to clamp metal sail crew ring to prevent it sliding, you could adjust the jib sail shape by moving the two rings position.
4. Use Clip supplied in tool bag to attach to eyelet in forestay fitting, Use forestay cord on jib sail tip to thread through a bowsie's two holes in proper order, then through eyelet in Clip, attach cord to end eyelet of bowsie(Tips: ensure bowsie is closer to forestay fitting for easy adjustment).
5. Cut a length of Dyneema cord at around 300mm, attach it to eyelet in jib sail tip, the other end of cord thread through a bowsie's two holes in proper order, then through eyelet in Clip, attach cord to end eyelet of bowsie. (Tips: ensure bowsie is closer to forestay fitting for easy adjustment). This cord is Jib Sail Lifting.
6. Use jib boom lifting cord to thread through a bowsie's two holes in proper order, then through eyelet in Clip, attach cord to end eyelet of bowsie.
7. Cut a length of Dyneema cord at around 250mm,attach it to jib boom tube between "SR2" and "SR3", the other end of cord is threaded through Deck Eyes 2 & 3, then tie a loop, loop around the Deck Eye 4 (Deck Eye 4 is already converted into a hook). This arrangement allows rigs to be changed quickly and easily with no necessary of bowsie adjustment. Now adjust three cord bowsies (Forestay cord, Jib Sail Lifting cord and Jib Boom Lifting cord) tight, so to make sure Jib Boom is 25mm-30mm top above deck level. Then adjust SR2, SR3's position on jib boom to pull jib boom, ensure jib boom end is around 5mm distance to mast.

MAST, JIB SAIL, MAIN SAIL ADJUSTMENT
1. Mast sliding mount is combined with fin box pre-set in factory as photo shown. This setting will ensure top of mast rakedback around 40mm from vertical line for a standard rig setup when backstay and forestay cord are pulled tighten. If mast sliding mount is not pre-set like this, you could use flathead screwdriver to loose mast sliding mount screw and move mast sliding mount forward or backward. Depend on different wind power, you need to learn yourself to adjust the mast sliding mount position, so that change the mast raked front or back.
2. Adjust bakstay cord bowsie and forestay cord bowsie to pull these two cord tension. 3. Adjust bowsie located in compression strut and rotate brass compression strut to pull mainsail tight after the above
rig has been setup. Adjust SR1 position on Jib Boom, Jib Sail Lifting cord bowsie to pull Jib Sail tight. Remember not to pull mainsail and Jib Sail too tight. 4. Normally, in strong wind, move SR2 and SR3 position to right side on Main Boom , move SR5 and SR6 position to right side on Jib Boom, so these setting can adjust the mainsail and jib sail's radian smaller. In light wind, move these rings' position to left side on Main boom and Jib boom, so these setting can adjust the sails' radian bigger. You need to learn youself in sailing to master the settings base on different wind power.

TRANSMITTER/RECEIVER BINDING
The binding process effectively ties the J4C05 transmitter and J5C01R receiver together. Under normal circumstances, both items are supplied like this from the factory. If, however, you find that your transmitter and receiver are not bound (receiver's red LED will be lighting), you should do the following:
1. Push down the throttle stick (Left Stick, MODE 2) till the end as shown. Switch "ON" the transmitter. 2. Switch "ON" the receiver by switching "ON" the battery box power button. 3. Press down the "BIND" button on the receiver as shown, until the receiver's red LED flash then let go, the receiver's green
LED will be lighting to indicate that binding has been successful and the receiver will now accept commands from the transmitter.
Note 1: You would also need to carry out the binding process if you were to replace the included receiver with another one. Note 2: Typically, for the binding process to be effective, transmitter and receiver should be no more than one meter apart and
no other similar devices should be within 10 meters of both during setup.

PREPARATIONS FOR SAILING
Before sailing your FOCUS V2 for the first time, take note of the following: 1. Always turn the transmitter on before the receiver, likewise, turn the receiver off before the transmitter. 2. Check that each sail, rigging rings and fitting is properly installed and adjusted 3. Switch off "MXMD" button on top position, because FOCUS V2 don't need mix control function. Following the procedures to check the radio and sailboat's function: (MODE 2 as example) 1. FOCUS V2 RTR is supplied with 2.4GHz 4CH radio system. For sailing the FOCUS V2, you will only need 2CH.
Please see following function of the transmitter.
2. For sail control stick, when stick is in the position of A, correspondingly, the main boom and jib boom are in the position of A as shown. When stick is in the position of B, correspondingly, the main boom and jib boom are in the position of B as shown. If this is not the case, simply move the sail servo reverse switch to the other position. You may also adjust the sail servo neutral by pressing the sail neutral position trim button up or down.
3. For rudder control stick, rudder turn left when rudder control stick is pushed to the left. Rudder turn right when rudder control stick is pushed to the right. If this is not the case, simply move the rudder servo reverse switch to the other position. You may also adjust the rudder servo neutral by pressing the rudder neutral position trim button left or right
4. Use supplied plastic screwdriver to adjust the rudder dual rate, this is to adjust the rudder throw angle from the centreline in either direction when the rudder control stick is moved to it's maximum throws. Refer to FOCUS V2 boat manual for the rudder throw angle.
5. Use supplied plastic screwdriver to adjust the throttle dual rate. This is to adjust the winch line travel distance between the fully sheeted in position (for sailing `close hauled' - close to the wind) and fully sheeted out position (for sailing on a `run' - sailing in the same direction as the wind with the sails fully out). Refer to FOCUS V2 boat manual for the winch line travel distance.

SAILING THE FOCUS û SAILBOAT
Unlike propeller driven boats that you basically point and accelerate, sailboats present an interesting challenge. Sailing requires constant reaction to water movements, any wind gusts, and any wind direction changes. These reactions then require adjustment of the rudder and sails in order to find the best possible course. There is no substitute for actual " on-the-water" experience and after your first couple of outings you may want to read through this manual again in order to help you to gain a better understanding of the "art" of sailing. While learning to sail, it is a good idea to pick up on as much sailing terminology as possible. This will make it easier to grasp some aspects.
How To Sail Focus û

IMPORTANT NOTICE: 1. Sail your Focus only in still bodies of water. Never sail your boat in running water such as streams or rivers, as it
is easy to lose control of your boat. 2. Never attempt to swim after a stalled or stuck boat! Wait patiently for the wind currents to return the boat to shore. 3. After running, remove the deck and allow the interior of the boat to dry out completely. If you neglect to do this, it may
result in corrosion of the electronic components.
