Build the ailerons
❏ ❏ 1. Locate a 1/4" x 3/8" x 30 [6.4 x 9.5 x 762mm]
balsa stick. Using the plan as a guide, cut the stick
as shown on the plan and glue the pieces together to
make the aileron.
❏ ❏ 2. Remove the aileron from the plan. Make a
mark at the center of the aileron at each end and
place a T-pin at each mark. Place a straightedge
along the aileron LE at the pins and draw a
centerline on the aileron LE.
❏ ❏ 3. Mark the location of the hinges and cut the
hinge slots using the same technique used for the
elevator and the rudder.
❏ ❏ 4. Shape the LE to a “V” and round the TE as
shown on the plan.
❏ 5. Repeat steps 1 - 4 for the other aileron.
Install the aileron control horns
❏ ❏ 1. Place a large control horn on the bottom of
the right aileron as indicated on the aileron plan. Use
a ballpoint pen to mark the location where the holes
need to be drilled.
❏ ❏ 2. Drill two 3/32" [2.4mm] holes for the control
horn mounting bolts through the right aileron.
❏ ❏ 3. Apply a small drop of thin CA in the hole to
harden the wood. Redrill the hole after the glue cures.
❏ ❏ 4. Attach the control horn to the right aileron with
two 2-56 x 1/2" [12.7mm] machine screws.
❏ 5. Repeat steps 1 through 4 for the left aileron.
Build the flap
❏ 1. You must build the flap regardless of whether
you are going to have it operational or fixed. The
construction steps are the same.
❏ 2. From 1/4" x 3" x 30" [6.4 x 76 x 762mm] balsa
sheet, cut the 1/4" [6.4mm] balsa flap TE doubler as
shown on the plan. Pin it in place on the plan.
❏ 3. Build the flap frame from 1/4" x 3/8" x 30" [6.4
x 9.5 x 762mm] balsa sticks. Cut the sticks and glue
them in place as shown on the plan.
❏ 4. Cut the 1/8" x 1/4" [3.2 x 6.4mm] balsa flap
diagonal braces as shown on the plan. When
satisfied with the fit glue them in place.
❏ 5. Sand both sides of the flap.
❏ 6. Round the flap TE as shown on the flap
cross section.

In the 1970’s the Contender was one of the
“must have” models. It was extremely popular
as a sport plane and was particularly well
suited as a fun fly contest airplane.
