The image below depicts the parts required for one wing.
The tools required for the conversion are;
- A Dremel or similar rotary tool
- A hobby knife
- UHU POR glue
- CA glue
A full build log is provided in the following video.
Cut both 800mm square carbon tubes to a length of 570mm and 230mm.
Making a slot in the Styrofoam wing 1.5cm deep using a rotary tool with some form of guidance to keep a fixed depth. The slot should be the length, depth and width of one 230mm square carbon tube. It should be located as indicated below.
Glue the 300x150x1.5mm carbon sheet to the 230mm carbon tube using CA glue and create an opening to run wires through. Insert the wires for power and signal to the ESC’s. Using UHU POR glue the sheet and carbon tube to the Styrofoam wing as indicated below.
Using CA glue, glue the 570mm square carbon tube to the carbon sheet. It should be located 285mm from where the wings join. The tube should be centred relative to the vertical area of the wing. It should extend exactly 165mm on both sides.
Attach the motor mount to the motor. With another motor mount plate and 4 M3x25mm screws clamp the motor on the end of the square carbon tube as indicated below. Attach the ESC’s with tie wraps to the carbon tube. When using the Afro ESC be sure to connect at least signal and ground wire.
