0 gap with rounded leading edges that are sunk into the wings/stabs, and all servos are concealed + serviceable. At a sub 2wh/km efficiency, Viper is capable of 100+km of total range with a considerable amount of battery capacity remaining for landing transition.

The values predicted are not perfect, and values like efficiency can vary greatly based on the choice of motor and propeller, among many other factors.

This is where the tilt servo mount will be bolted to.

Section 4: 3D printing 4.1: Things to know before you start printing. 1. Titan Dynamics strongly recommends using Polymaker Polylite prefoamed LWPLA for the best results. This filament is much easier to tune your printer for and has less stringing than active foaming filaments.

This link can be used to download our own slicer profile. 4.2: Part Orientation It is necessary to orient each part correctly on the build plate to avoid disconnected overhangs.

Re-open any holes the tab may have filled on the bottom of the print.
Below are a few exploded views of the Viper to help with assembly. The spar layout for Viper is as depicted below. None of the spars need to be glued in, they will all be retained by the printed parts. The two wing spars that intersect the fuselage are the joiners for the wings and the fuselage and can be removed completely from the fuselage and wing during transport.

Section 8: Ardupilot setup tips Please read in detail the documentation for setting up quadplanes on Ardupilot: https://ardupilot.org/plane/docs/quadplane-building.html Viper is a tri-tiltrotor. The front two motors tilt while the rear is stationary. Q_FRAME_CLASS = 7 Q_TILT_MASK = 3 Q_TILT_TYPE = 0 Please read in detail the setup instructions for tilt rotor VTOLs here: https://ardupilot.org/plane/docs/guide-tilt-rotor.html...
