5. D GROOVE OUT THE ELEVATORS FOR JOINER WIRE
CLEARANCE
Cut a groove in the elevator leading edge inboard
(inside) of the hole so when the joiner wire is installed it
will be flush with the leading edge of the elevator. Groove
both elevator halves.
6. D TRIAL FIT THE JOINER WIRE
Temporarily install the elevator joiner wire into the
elevator halves. Check to make sure that this assembly is
aligned properly. Bend the joiner arms if necessary for a
perfect fit. DO NOT GLUE THE JOINER WIRE TO THE ELE-
VATOR HALVES UNTIL AFTER THE PIECES ARE COVERED
LATER.
7. D CUT HINGE SLOTS FOR THE STAB AND ELEVATOR
Mark and cut the hinge slots for the stab and eleva-
tor halves as you did with the fin and rudder. See the plans
for locations. Shape the leading edges of the elevator
halves to a "V".
BUILDING THE WING PANELS
READ THIS FIRST BEFORE YOU START BUILDING THE
WING PANELS: It is very important that you build a straight
wing with no warps or twists or you will get some flying
characteristics you didn't expect! Be very careful when
you align the ribs, spars, leading edges and trailing edges
and sheeting at the various steps below. All these parts
should be in their correct positions before you glue them in
place. Hold or pin the parts in place, then glue. Use the
following instructions to help you build the wing straight
and warp free.
Remember: Anyone can build a wing. Only a careful builder
can build a straight wing.
1. D NOTCH THE RIBS FOR LANDING GEAR BLOCK
CLEARANCE
Notch the ribs to be installed at locations 2 and 3 for
the hardwood main landing gear blocks. Conventional
gear block notches are forward on the ribs. (Tricycle gear
notches are the rear cutouts.) Check the fit with the block.
Number these ribs 2 and 3. Cut the notches in the ribs for
the other wing panel at the same time. (Conventional gear
cut outs are shown.)
* 20 size ribs are notched already. Glue the scrap back in-
to the notch you will not use.
