The nose fixture is used to assemble the front of the 

fuselage.  Put the bottom of the fuselage into the 

fixture snug against the front stop and then line-up 

and glue one side of the fuselage while holding the 

side tight against the fixture.  Only apply glue to the 

front 3½" of the fuselage (the point where the fixture 

ends).  Repeat for the other side. 

 

Move the partially assembled fuselage from the nose fixture to the full fuselage fixture.  

The front of the fuselage will not be against the bottom of the fixture.  Now glue the 

right and then left fuselage sides to the fuselage bottom.  Keep the sides tight against 

the fixture until the glue sets.  The rear of the 

fuselage is easier to assemble using foam safe 

CA. A glue gun is hard to get into position to 

glue the joint as the fuselage tapers at the rear. 

 

Foam nose and rear dowel doublers are optional.  

They were designed before the plywood fuselage 

doublers were added to the kit.  Nevertheless, 

they still provide an increased surface area for 

attaching the firewall and dowels.  If desired, 

glue the doublers in place making sure the holes 

for the hold-down dowels are lined up.  The 

finished inside width in the nose is 1¼".  If your 

battery is wider than this, you may want to cut 

off part of the bottom of the nose doublers to provide more space. 

 

Remove the partially assembled fuselage from the fixture. 

 

Now glue the front and rear fuselage tops to 

the fuselage sides.  

Tip: Place the Horizontal 

Stab in the slots to support the rear of the 

fuselage sides while installing the rear top 

piece.  You may need to spread the sides to 

get a good fit with the fuselage tops.  

Hopefully you now have a fuselage that is straight and doesn’t look like a blue banana! 

 

Tip:  Add a strip of strapping tape along the bottom of the fuselage 

to protect the bottom when landing on rough surfaces. 

 

Hood Scoop: 

 

Next is the plastic spoon “hood scoop”.  Hey, this is a racer!  Racers 

have hood scoops for a reason and this one is used to get outside air 

into the fuselage for cooling the ESC and battery.  The kit includes a 

precut spoon.  The picture at the right show how the hood scoop 

was cut from the plastic spoon.  Place the hood scoop on the top of 

the fuselage and draw an outline of it.  Remove the hood scoop and
