BASIC BOAT TERMINOLOGY

BOW: The front of the boat.
STERN: The back of the boat.
PORT: This is the left side of the boat when view the boat from the stern. An easy way to remember this is that port and left both contain four letters.
STARBOARD: This is the right side of the boat when viewing the boat from the stern.
HULL: The body of the boat.
DECK: The top of the boat.
KEEL: A weighted blade that protrudes from the bottom of the hull as a means of providing lateral stability.
RUDDER: The hinged vertical plate mounted at the stern controls steering.

DISPLAY STAND ASSEMBLY

1. Installed screws into the plastic boat stand parts with a 2.5mm allen key
2. Follow No.2-6 photos to assemble the boat stand.
3. Locate the EVA gasket on the hull support as pictures 7 and 8 shown. This will protect the hull bottom from scratches during construction and storage.

KEEL & BALLAST & RUDDER ASSEMBLY

1. Secure keel and ballast with M6 nut and flat-head screwdriver.

2. Assembly the rubber ring on the top of the keel, then secure the keel and hull with a metal ring, M6 nut, and flathead screwdriver.
   

3. Insert the rudder shaft up through the bottom of the stern of the hull. Notice the rudder’s direction. Use 2.5mm Allen key to secure the rudder shaft on the rudder arm. Make sure the rudder can freely rotate and the gap for up and down is no more than 0.5mm

4. Pushrod goes through clevis on rudder arm, make sure rudder is on the center line of the hull, then use 2.5mm Allen key to tighten clevis screw.
   

MAIN SAIL RIGGING

1. Use mast fitting tube (longer side) to thread through bearing on the main boom, insert mast fitting tube in main mast mount as shown. See page 6.
2. Insert long mast in mast fitting tube (shorter side). See page 6.
3. Thread three mainsail luff rings through the long mast and thread the top one mainsail luff rings through the short mast, See page 6.
4. Assembly Carbon backstay crane set and insert it into the short mast, See page 6.
5. Insert short mast into the long mast with mast fitting tube. Cut a length of Dyneema cord at around 2300mm, attach it to Carbon backstay crane eyelet, the other end of cord thread through a browser’s two holes in proper order, through stern eyelet then attach the cord to the end eyelet of browser. adjust cord bowtie to pull cord tight and straight, See page 6.
6. Cut a length of Dyneema cord at around 100mm, use it to attach eyelet on mainsail tip to Carbon backstay crane left the second eyelet. Notice that gap between the mainsail tip and the Carbon backstay crane is within 6mm-10mm, See page 6.
7. Adjust silicone rings (“SR” for short) positions on the main boom as shown.
8. Cut a length of Dyneema cord at around 250mm, attach it to the eyelet located on the top of the main boom bearing, the other end of cord thread through eyelet in the bottom left corner of mainsail from the front side to backside, then through the eyelet on the bottom of the main boom bearing from backside to front side, then thread through a browser’s two-hole in proper order, through the compression strut fitting eyelet, at last attach the cord to the end eyelet of bowtie, adjust browse to pull mainsail tight.
9. Use a metal sail crew ring between SR2 and SR 3, to hook the eyelet on the bottom right corner of the mainsail, the two rings are used to clamp the metal sail crew ring to prevent it from sliding, you could adjust the mainsail shape by moving the two rings position. Use your hand to rotate the brass compression strut to adjust the angle between the main boom and mast. After getting the angle you want, screw the nut tightens to secure firmly the brass compression strut. So that the main boom could pull the bottom right corner of the mainsail tight. But remember not to pull the mainsail too tight. See page 6.

MAIN SAIL RIGGING

JIB SAIL RIGGING

1. Adjust silicone rings (“SR” for short) positions on jib boom as shown.
2. Use a forestay cord on the bottom left corner of the jib sail to tie a loop, then loop around the jib weight shaft. Cut a length of Dyneema cord at around 100mm, attach it to eyelet in the bottom left corner of jib sail, the other end of cord thread through the eyelet in jib boom front end fitting from backside to front side Pull the cord to make sure jib sail is 3mm-5mm top above jib-boom, then attach the cord to silicone ring “SR1” on jib boom. Adjust SR1 position to adjust jib sail distance from Jim boom.
3. Use a metal sail crew ring between SR5 and SR 6, to hook the eyelet on the bottom right corner of the mainsail, the two rings are used to clamp the metal sail crew ring to prevent it from sliding, you could adjust the jib sail shape by moving the two rings position.
4. Use Clip supplied in the tool bag to attach to an eyelet in forestay fitting, Use the forestay cord on the jib sail tip to thread through a browser’s two holes in proper order, then through the eyelet in Clip, attach the cord to the end eyelet of browser(Tips: ensure bowtie is closer to forestay fitting for easy adjustment).
5. Cut the length of the Dyneema cord at around 300mm, attach it to the eyelet in jib sail tip, the other end of cord thread through a browser’s two holes in proper order, then through the eyelet in Clip, attach the cord to end eyelet of browser. (Tips: ensure bowtie is closer to forestay fitting for easy adjustment). This cord is Jib Sail Lifting.
6. Use a jib boom lifting cord to thread through a browser’s two holes in proper order, then through the eyelet in Clip, attach the cord to the end eyelet of the browser.
7. Cut a length of Dyneema cord at around 250mm, attach it to a jib boom tube between “SR2” and “SR3”, the other end of the 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 without the necessity for bowtie adjustment. Now adjust three cord browsers (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, and ensure the jib-boom end is around 5mm distance to the mast.

MAST, JIB SAIL, MAIN SAIL ADJUSTMENT

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

MAIN BOOM & JIB BOOM RIGGING 

1. Slide off the battery door on the back of the transmitter. Install 4 fresh“AA” alkaline batteries into the transmitter in the configuration molded into the battery compartment. Re-install the battery door onto the back of the transmitter.

2. Push down the throttle stick (Left Stick, MODE 2) till the end as shown. Switch off the “MXMD” button on the top position, because Focus Ⅱ sailboat doesn’t need a mix control function. Then turn on the transmitter by pressing on the power switch.

3. Take the battery box for the receiver out from the servo plastic tray inside the hull, and install 4 fresh “AA” alkaline batteries into the battery box. Switching the power button on, to check whether the receiver is bound already with a transmitter or not. If not, see the following pages of TRANSMITTER/RECEIVER BINDING for reference. Replace the battery box on the servo plastic tray and use a rubber band to tie the battery box securely in place as shown.
   REMARK: If the receiver has already been bound with the transmitter, the rudder servo will automatically return to a neutral position, if rudder servo is still not in the neutral position, adjust the rudder neutral trim, see following pages for reference.

4. Now sail control stick (left stick) push down till the end, the sail winch servo pull cord tight. Pull out the Switch rod to switch off the receiver and switch off the transmitter. Note: if the sail control stick (left stick) pushes down, the sail winch servo loose cord, then you need to move the sail servo reverse switch (CH3) to the other position

5. Cut a length of Dyneema cord at around 650mm, tie a loop, and hook it on the clip as shown, the other end of the cord thread through deck eye 8 and mainsheet deck eye as blowing marked, then through boom bend eye and through bowie’s two holes in the proper order(tips: bowie closer to boom end eye for easy adjustment), then through the rubber ring and the other boom band eye, then attach it to one end eyelet of the browser, Make sure the main boom is pulled as on the centerline of the hull. If not, adjust the bowtie to pull the main boom tight.
   

6. Cut a length of Dyneema cord at around 700mm, tie a loop, and hook it on the clip as shown， the other end of the cord thread through deck eye 8, 7, and 6, then through boom band eye on jib boom between SR4 and SR5, then through rubber ring as shown and through browser’s two holes in the proper order(tips: bowtie closer to boom end eye for easy adjustment), then through another boom band eye, attach it to one end eyelet of a bowtie. Adjust bowtie, push jib boom away on either port or starboard, to make sure rear-end of Jibboom is moved away from mast at 30mm-35mm.
   
   

7. Switch on transmitter and push in Switch rod on deck. If the transmitter power indicator light flashes, push up the throttle stick till the top end, then push down till the lowest end again, transmitter power indicator light should be solid on, and now the transmitter is activated. Push up sail control stick( Left stick), sail winch servo will lose all cord out, move Mainsail and Jibsail away till the maximum angle, to make sure Mainsail could travel about 80°, Jibsail could travel about 80°, if not, adjust boom band eye and SR1 position on MAIN BOOM to adjust its traveling angle. Adjust boom bend eye and SR4 position on JIB BOOM to adjust its traveling angle.

8. Move rudder control stick (right stick) left and right, rudder traveling angle to left and right are both around 35°. if not, adjust the rudder servo neutral by pressing the rudder neutral position trim button on the transmitter left or right. if still can’t get it right, adjust the pushrod by losing the screw-on rudder arm.
   

9. Rotate counterweight on front of jib boom by clockwise direction, adjust counterweight position, to make sure jib boom swing CG is located on SR2 and SR3 of Jibboom.

10. Turn off transmitter and power switch on deck, check all the cord ties and rigging, then apply cloth patch on deck hatch. It can be re-used many times.
    

Mode 2

NOTE:

1. MXMD button is mix control ON/OFF button, switch up as “OFF” because FOCUS V2 doesn’t need mix control.
2. Supplied plastic screwdriver on transmitter handle, use this part to adjust Rudder & Throttle dual rate.
3. Connect up the Servo, Winch and Battery Switch Cables up to the Receiver as follows:
   – Rudder Servo plugs into Channel 1 socket.
   – Sail/Winch plugs into Channel 3 socket.
   – On/Off Switch plugs into any rest socket

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 (the 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 flashes 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, the 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 ring, and fitting is properly installed and adjusted
3. Switch off the “MXMD” button on the top position, because FOCUS V2 doesn’t need a mix control function.

Following the procedures to check the radio and sailboat’s function: (MODE 2 as an example)

1. FOCUS V2 RTR is supplied with a 2.4GHz 4CH radio system. For sailing the FOCUS V2, you will only need 2CH. Please see the following function of the transmitter.
2. For the sail control stick, when the stick is in the position of A, correspondingly, the main boom and jib boom are in the position of A as shown. When the 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 the rudder control stick, the rudder turn left when the rudder control stick is pushed to the left. The rudder turns right when the 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 a 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 its maximum throws. Refer to the 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.

TRANSMITTER MODE SWITCHING

J4C05 2.4GHz 4CH transmitter is supplied with MODE 2 as the standard set, If needed, you could simply switch to MODE 1 by The easy steps as below:
Step 1: Open the battery cover, and switch the MODE button to MODE 1.
Step 2: Use a screwdriver to screw down the up-left screw tightly as the photo is shown.
Step 3: Screw down the down-left screw as the photo shows, but not fully tighten, adjust this screw tightness so as to adjust the throttle stick (right stick) spring tightness as you wanted.

Step 4: Screw off the down-right screw completely until the screw head is almost even with the back panel.
Step 5: Screw off an up-right screw, but not completely. adjust this screw tightness so as to adjust the Elevator stick(left stick) spring tightness as you wanted.

NOTE: If switch back from MODE 1 to MODE 2, firstly switch MODE button to MODE 2 under the battery cover, screw off the left two screws, Screw down the right two screws, and adjust the down-left and up-right screws’ tightness so as to adjust the Throttle stick and Elevator stick spring tightness as you wanted.

SAILING THE FOCUS Ⅱ SAILBOAT

IMPORTANT NOTICE:

1. Sail your Focus Ⅱ 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.
