Wing Construction

KI-61 Wing Construction plan
The wing construction is fully detailed on full size 1:1 scale CAD drawings. Wingspan of this model is 34" and wing area is 165 sq. inches.

NOTE: The wing construction of the Kawasaki KI-61 shown here is built in the same manner as other TDM Models. Please refer to the wing construction sequences on other models for more details of wing construction that may not be shown here. Specifically, please see the IL-2 wing construction sequences parts 1, 2 and 3 for additional detail.  

The wing is all balsa construction consisting of 1/16" thick balsa skins and internal 1/16" ribs. Here is a photo showing the basic wing construction prior to installing the top sheeting. The wing is assembled flat on the building board. The laser cut ribs are glued to the bottom wing skins. The inside surface of the lower skins are etched to show the wing rib locations. Install your aileron hardware then glue the ribs to the bottom skins. Add the 1/16" sub leading edge to the nose of the wing ribs.
This photo shows wing construction detail at the right aileron. The aileron is incorporated into the basic wing structure and cut free after the top sheeting has been added. The aileron spars are 1/8" balsa and the aileron ribs are cut off trailing edges of the main wing ribs. Scrap balsa is glued at the inboard end of the aileron to support the aileron actuator wire which is made from 1/16" music wire.
After the top wing sheeting is added the 1/8" balsa leading edge cap is added and the solid balsa wing tip blocks. The wing tips are shaped with #80 sandpaper and blended into the airfoil shape of the wing panel tip, leading and trailing edges.
The wing panels are complete and the ailerons are cut free from the main wing panel.
A close up view of the left aileron showing it cut free from the main wing. Make sure you DO NOT glue the aileron actuator rod to the lower wing skin when you install it or removing the aileron at this stage will be a problem.
Glue the wing plans together at the root rib by blocking up each wing tip 1". Use the aileron dihedral gauges shown on the plan (or provided in the short kit) to get the wing dihedral accurately built into the wing. After joining the wing panels add a strip of .50 fiberglass cloth around the center section join to increase the strength of the joint.
