5. Install the landing gear wire in the wood mount with 
four 3x10mm wood screws and landing straps. You may 
need to drill 2mm(5/64 ) pilot holes before screwing in 
the wood screws. Also change the main landing gear 
wires come with the kit.  If wire can not fit the wood 
mount then you can trim or change new wood mount.

ASSEMBLY:

6.Refer to the airplane C.G. and determine the location 
of the mounting bracket.  You will need to check the 
length of the two landing gear block and make sure the 
STEP of float is about 10mm(3/8 ) to the C.G. position. 
Now you can find out the correct position for four 
mounting brackets then make marks on the mounting

Q'ty          

Before assembling the float set we suggest to remove all the 

flash

 by using 200-grit sandpaper. The float 

set is not necessary to paint.  If you would like to paint the float and (or) other parts, this is the time to do it. 
We do not recommend to paint the bottom of the floats. Please refer to the following points and carefully 
proceed the painting procedure. 
     Wash all of the model with soap and water to remove any grease.
     Sand the entire surface to be painted with wet 400 grit sandpaper.

    (You may avoid sanding the aileron, elevator and rudder moving part if you wash them well).

 Use any fuel resistant paint that you like, we have had good result with 

 Isofan

 , 

 ABF

 or two-

component polyurethane paint.

    Test the paint on other ABS material before you paint on the float.
     Make sure the paint and thinner will not melt or damage the ABS material. 
     Apply some drops of nitro fuel on the painted ABS sheet to make sure if the paint is fuel resistant.
     Mask tape is needed for the painting job to cover the unpainted area.   
     Avoid to paint the glue area as CA may damage the paint and cause bad adhesion. 
     Make sure the linkage is smooth; if not ,remove the paint at the linkage area.
     Always wear mask w/filter when doing the painting job as thinner and paint are harmful to your health.

7.Drill 5mm(13/64 ) holes on the  marks  at  least  30mm
( 1-3/16 ) in depth. Disregard the molded dots on the 
float as they might not at the same position as the marks 
you made. Trial fit the plastic sleeve and make sure the 
depth is just flush with the sleeve, remove the sleeves 
and roughen the plastic sleeves with sandpaper(150 grit). 
Glue all sleeves in place with epoxy. Note that the holes 
are faced up.  Make sure there is no epoxy inside the 
hole of sleeve.

8.Sand the glue area of the plug and the hole on the float, 
next epoxy the plugs in place.  Note the plug w/Rudder 
Bush will be at the left float which you will need to drill an 
extra hole for the angles brass tube mount later.

9.Locate the Water Rudder, Rudder Shaft and Rivet. 
Insert the rivet then use hammer to secure the rudder in 
place.  Note: The rivet has a hole on one end, suggest to 
place a Phillips Screw Driver on the hole then slightly hit 
the driver so the rivet will break evenly.  Next hit the rivet 
directly until water rudder is secured firmly but still can 
swivel back.

2. Locate the wood block then use saw to cut away the 
excess part base on the outer dimension

  Epoxy the 

two torque wood block on the landing gear wood block 
base on the inner dimension

3.Drill 4.2mm (

11/64 )

 holes through the torque wood 

mount center on the landing gear wood block groove at 
two ends about 10mm(

3/8 )

 to the edge which depends 

on the thickness of side fuselage.  Note the two holes 
are not in line with each other so two landing gear wires 
could be installed in the groove.

4.Trim a  

“U

cut right after the firewall so the landing 

gear wood mount could be installed.  Trial fit and trim the 
U cut make sure the wood mount is level with the bottom 
fuselage.  Apply enough epoxy and glue the wood mount 
in place.

10 Install the water rudder in the plug w/bush then 
secure the Steering Arm in place with 2.6x8mm wood 
screw.

11.Apply decals carefully as photo shown then secure 
the mounting brackets in place with 3x15mm wood 
screws. Note the orientation of the mounting brackets. 
Next install the collars and carbon tubes as shown, 
adjust the tube then secure the collars with eight 3x3mm 
setscrews. Make sure there is no gap between the collar 
and mounting bracket.
