760mm] balsa leading edge and glue it to the sub-leading
edge of the wing. Cut the portion of the leading edge that
extends past the tip rib and W2. Sand the leading edge to
shape as shown on the plans cross section.

position. Sand the block to shape as shown on the plans.

Retractable Mains/Fixed Tailwheel landing gear cut-out
template and place it as shown on the sheeting on the

place it on the sheeting on top of the wing. Cut the opening
for the retract servo in the top sheeting.
