Apologies again for the long overdue update. Some significant assembly progress is being made, but NAVI still is not ready for a flight test quite yet.
Things left to do is get another set of 2.5mm linkage balls (ordered but shipping from China >.<), design an avionics and battery mounting plate, assemble the rest of the cable harness, and configure the flight controller. Below is a picture of the project as it currently sits, however. Cheers :)
