TAA USAF Designation: A74-1
Step 2: Fourth Folding
Step 3: Corner Folding
Step 4: Tuck Folding In Preparation For The Landing Gear
On the triangular front, there will be a crease which parallels the airfoil. To start to prepare your landing gear, fold it so it sits on the side of the paper where the cover fold isn't. Then when this is done, pull it back over so that it sits on top of the cover folds. From here, pull the paper of the edges of the cover fold up and over this small triangle at the front. When they are pulled over the triangle, pull them back down so the uppermost parts layer back down above the triangle as illustrated. Unfold the edges of the paper and then insert both into the triangle's slots. When this is done, the edges you folded down to the size of the triangle should fit inside of the triangle they were measured to. Tuck each in, and this step is complete.
