Parts for an RC airplane with a carbon arrow shaft as the body. The arrow I used is from a bi-mart 3 pack and has a diameter of 7.5mm. I used and emax rs2205 with a 6" propellor, little bee 30A ESC, and a 1300mah 4s lipo. The wing is about 30" wide and made from DTFB and instructions from: https://bit.ly/2sfmlhL

I used some tg9e servos from hobby king and hot glue, super glue, tape, and zip ties. Oh I did end up buying a roll of servo wire to extend the wires from the tail forward. The tail was just some made up dimensions and I cut it with a razor blade, boom.

You might want to use a bigger motor and prop for efficiency, but this setup provided plenty of power and speed for comfortable flight.

Also I used OnShape to design the whole thing. If you need to copy the files to tweak it for your own needs feel free. https://cad.onshape.com/documents/67ccd396fd9c8bff1ca0a789/w/3802d878ae666a645a8e303f/e/bf6a9957cafc414d90e37962
