Onslaught is a relatively easy paper airplane to fold and it flies excellently. This plane has fairly wide wings, but their strong leading edges allow this plane to be thrown as hard as you like. As with many planes, you may want to bend the back edges of the wings up ever so slightly to improve its balance, but give it a test throw before you do. It might fly perfectly without needing any adjustment. Give it a good launch and Onslaught will impress you when it soars to the far side of your gym!
