Man took me forver to type all this
1. MOTOR MOUNT
Install the motor mount using 3/4x 8-32 screws. Use a 5 inch wide Octura Humdinger mount or Speedmaster universal mount.
2. STRUT/DRIVE SHAFT
Mount the strut on the boat thru the bottom of the hull set the depth of the strut to ¾" deep.
Cut out the slot for the strut and the drive shaft tube. The hull is marked with the location of the cut outs. The shaft tube runs straight down from the engine to the strut with no bend in it.
Use a 9/32 tube for the shaft tube to be glued into the hull. The ¼ cable shaft tube will slide thru this tube and thru the strut.
With the motor mounted on the mount and the strut set at the ¾ inch depth, enlarge the drive shaft slot until the tube lines up with the engine nut. Insert your cable drive shaft thru the strut and brass tube and into the engine nut.
Tack the brass tube into the hull with CA glue. Glue a ¼ inch wood wedge under the front of the tube to support it.
Tape up the slot on the bottom of the hull and use epoxy and glass cloth the glue the drive shaft tube into the hull.
On final assembly of the ¼ shaft tube make a couple of bends in the tube before pushing it into the 9/32 tube so that it will not spin with the flex drive shaft.
3. RUDDER
Mount the rudder on the left side 2 ¼ " from the center. Use a stiff control rod to the radio box a fiberglass aero shaft works best. Use a high power standard size servo for the rudder.
Do not use too much rudder throw, about 5 degrees will turn the boat.
4. TURN FIN
Mount the turn fin on the line marked on the hull. Use 8-32 screws for the mount. Drill and tap the aluminum plate in the rear of the sponson. Install the turn fin on the inside of the mount. Sharpen the outside edge of the turn fin.
Check the alignment of the fin, it should be straight. Use a straight edge or ruler held against the fin. Twist the fin until it is parallel with the sponson running pad. A misaligned fin will cause the boat to pull left or right or spin out when turning left. See diagram for bottom view.
5. FUEL TANK
Mount the fuel tank with wood blocks with hooks and rubber bands to hold it in place. Use a 14 oz DUBRO tank or a SULLIVAN 14oz SS tank for the rear radio boat setup. The front radio boat set up should have the tank mounted in the right deck next to the motor.
A Sullivan 12oz RST tank will fit. You should use a hopper tank to feed fuel to the carb.
A Hayes 2oz or a Sullivan 1 ½ oz tank will work for a hopper tank.
Tanks 2 U makes a 14oz. metal tank for this boat.
6. RADIO BOX
The rear radio box should be mounted as close to the motor as possible. Allow clearance for the engine cable nut . The front box sits in front of the engine, the control rod for the carb is short, a Bruline #100 boot should be used here to allow movement of the control rod. Turn the carb so that the throttle arm is on top if possible.
Use a stiff control rod for the rudder link, A carbon fiber push rod is best. Use a Sig #SH654 or Dave Brown Products control rod. Mount the radio box with wood blocks with hooks and rubber bands to hold it in place.
7. COWLING
Mount the cowl using Aeromarine pushbutton latches. Install the latch mounts six inches from the rear of the engine well. Set the cowl on the hull and mark the cowl where the latch sockets show thru the glass, drill a 5/16 hole for the push buttons.
Use some 1/16 ply for a base to stiffen the cowl sides so it will not flex too much. Cut out the air scoop or slots in the cowl to ventilate it. The rear deck can be removed and fastened directly to the hull , this will prevent it from breaking off in case of a blow over.
8. FINISHING THE HULL
Finish the hull seam with a course sanding block, fill any small gaps or air bubbles with gap filling CA and quick set spray. Cut out the slots for the front canard wings on the marks on the nose. Insert the canards into the slots and level them, mark the sponson side and cut out the slots for the canards to fit into. Epoxy the front canards into the slots.
Drill some ¼" drain holes in the transom to allow water to drain from the hull after running. Place the drain holes in the upper corners of the transom above the waterline. A drain hole can be used in the rear of the engine well floor also.
Dull the surface of the hull with a green finishing pad, do not sand into the glass cloth, this will cause pin holes
Use epoxy primer and fill any pinholes you find with glazing putty. paint the hull with epoxy or polyurethane paints. Apply at least 3 light coats of clear to ensure your paint job will be fuel proof.
Add some flotation to the hull and to the cowl. Use foam pipe insulation tubes for the hull. Do not use spray foam it will soak up oil and water and add weight to your boat..
9. TRIMMING THE BOAT
The ¾ inch strut depth is a good starting point. If the boat rides too light on the water, adjust the strut deeper. If the front sponson are running too hard on the water adjust the strut higher until the boat rides flat on the water but will not blow off. Small adjustments to the strut angle can be made also. Weight can be added to the nose to fine trim the hulls balance point if needed. The hull should balance about 17-18 inches from the transom without fuel.
Once the boat is set up correctly no changes should be necessary for smooth or rough water other than adding weight to the nose. On a calm day the boat may spray water from the forward steps of the front sponson, raise the strut to lighten the boats ride, but be careful not to make it too loose when racing on rougher water. In rough water the boat may look like it is too loose on the water, do not change the trim unless the boat tends to blow off.
The Super Sport 45 should handle rough water and turn flat without losing control.
Mount the servos with 1 /4 x 3 /8 spruce stick. Use CA glue to fasten the stick to the box
Locate the servos to suit your setup. The typical servo setup is shown in the diagram. Use Bruline #100 rubber boots or G.E.M. silicone seals for the control rods. The Bruline boots allow more side to side movement.
Mount the radio antenna on the radio box lid, take care to provide clearance for the tuned pipe. The antenna wire can be run out of the box and mounted on the deck next to the radio box. DO NOT mount the antenna on the transom of the boat due to possible radio interference.
Use plastic tape to seal the lid on the box, cut a hole in the lid for access to the charge plug, seal this hole with tape.
Mount the radio box in the hull with hooks screwed into wood blocks, use rubber bands to hold the box in position. Use a carbon fibre tube for the rudder control linkage.
