With the elevator’s pushrod housing ‘stretched’ through the fuselage, confirm the aft-end of the 

elevator’s pushrod will be able to reach to where the elevator and its control horn must be attached 

behind the top of the vertical stabilizer. Using epoxy, permanently attach the vertical stabilizer to the 

top-aft portion of the fuselage. Before the vertical stabilizer’s epoxy has noticeably thickened, make 

certain the vertical stabilizer is aligned along the length of the fuselage and vertically to the bottom of 

the fuselage and wing-saddle, then apply masking tape to securely hold the vertical stabilizer in 

position. Set the fuselage and vertical stabilizer assembly aside and allow the epoxy to cure fully. 
Test-fit the horizontal stabilizer to the top of the vertical stabilizer. Use the tip of a hot soldering iron 

to burn (or carefully cut) and remove covering material as necessary to obtain good wood-to-wood 

gluing surfaces between the top of the vertical stabilizer and the bottom-center of the horizontal 

stabilizer.  
Using epoxy, permanently attach the horizontal stabilizer to the top of the vertical stabilizer. Before the 

horizontal stabilizer’s epoxy has noticeably thickened, make certain the horizontal stabilizer is aligned 

parallel to the bottom of the fuselage and to the wing-saddle, then apply masking tape to securely hold 

the vertical stabilizer in position. Set the fuselage with its vertical stabilizer and horizontal stabilizer 

aside and allow the epoxy to cure fully. 
Using the bottom of the supplied elevator pushrod fairing  

as your guide, use the tip of a hot soldering iron to burn (or 

carefully cut) and remove enough covering material from the 

bottom of the elevator pushrod fairing and the top-center of 

the horizontal stabilizer to obtain good wood-to-wood gluing 

surfaces. 
Slide the elevator pushrod fairing over the elevator pushrod’s 

housing and use epoxy to permanently attach the elevator 

pushrod fairing to the top of the horizontal stabilizer. 
Attach the elevator to the horizontal stabilizer using the  

supplied CA hinges, the precut hinge slots, and CA adhesive. 
Using a Z-bend in the end of the elevator’s pushrod, attach the 

elevator’s control horn to its pushrod, then attach the control 

horn to the elevator in line with and directly behind the 

elevator pushrod fairing and elevator pushrod. 
Use epoxy to permanently secure the small triangular- 

shaped fin to the bottom of the fuselage in line with the  

aft-end of the vertical fin. (NOTE:  some customers choose  

not to install this small fin to better enjoy ‘drifting’ through  

turns on the water.) 
If necessary, cut the covering material to open the rudder’s  

precut CA hinge slots. Then permanently attach the rudder  

to the vertical stabilizer, fuselage and bottom fin using CA  

hinges and CA adhesive. 
Using a Z-bend in the end of the rudder’s pushrod, attach the 

rudder’s control horn to its pushrod, then attach the control 

horn to the rudder in line with and directly behind where the 

rudder pushrod exits the fuselage.

 

Test-fit then attach one end of the tail-section struts to the  

sides of the fuselage. Or, if you prefer, attach them to each side  

of the vertical stabilizer as pictured on page 1 of this manual.  
Attach the upper ends of the tail-section struts to the wooden  

‘hardpoints’ in the horizontal stabilizer as shown at the right.
