To demonstrate the measures I have uncovered, I will use several aged Hammerhead paper airplanes to demonstrate various features that increase the abilities of aged airframes. The benefits of these features are not limited to the Hammerhead, but it is more versatile and able to have these add-ons applied with ease than several other aircraft. The add-ons are independent of one another, but incurring all 5 can be favorable for certain requirements.
