High wing trainer prototype

thingiverse

This is my latest 3D printed plane prototype, designed to surpass its predecessor in every way. The first iteration was far too heavy, so I've opted not to share those details. This new design is already showing promise, with a significantly reduced weight and increased wingspan. I print all pieces except the electronics flat, ensuring that none require supports. The electronics bay should be printed as shown, taking note of its unique orientation - it's not perfectly vertical by intention. My build method involves assembling the skeleton first, followed by attaching tape hinges to the ailerons. I'll cut foam board for the rudder and elevator, then add servos to bring this design to life. The lightweight skin will be crafted from tissue paper, doped with hairspray for added durability. The electronics bay is removable, secured in place by two BBQ skewers. These skewers also provide a convenient spot to attach a wire front landing gear, held fast with rubber bands. Rubber bands are used again to secure the wing in place, passing through holes in the fuselage. The wing halves can be joined using BBQ skewers, giving builders the flexibility to make this feature permanent or not. This design requires 4x sg90 servos and a power source comparable to the Flite Test Power Pack C. As this is a 3D printed plane, it needs more power than its balsa counterparts. The electronics bay can accommodate a large LiPo if needed. To add flaps and ailerons, simply replace the flap trailing edge piece with an aileron, and create a second set of ailerons to function as flaps. I'll continue to update this project as it progresses.
