V1 Buzz Bomb Construction Manual

Sand the inboard trailing edges so that 
the last 1/2” of them tapers from 1 mm 
to a sharp edge.

Using a straight edge and a single-
edged razor, ensure that one edge of 
the 1 mm x 6” balsa upper sheeting is 
completely straight.

Run medium CYA along the straight 
edge of this sheeting, and glue it to the 
back of the leading edge, so that it is 
touching all of the ribs.  Use a straight 
pin over each rib to ensure positioning.  
Fill any gaps with a gap filling glue that 
can be sanded, such as PICA Gluit.

Do not glue the sheeting to the ribs yet.

When glue is dry, carefully roll sheeting 
down on ribs, until aileron torque rods 
poke up through sheeting.  Lift it back 
up, and cut 1/4 wide by 1/2 long slots 
around the holes made by the torque 
rods.

Completed slots for aileron torque rods.
