Table 1: COMPONENT LIST
PRISM was created to be propulsion-system agnostic, meaning it can fly as either a
quadcopter or coaxial x8, with any motor/ESC/propeller. Each propulsion system arm is
user-changeable by removing only two screws. This allows users to change the propulsion
configuration according to their needs. This gives users the freedom to change between
a quadcopter or a coaxial x8, or replace one individual propulsion system in the event that
one is damaged.
Watts Innovations intends to offer various propulsion systems for PRISM. The current
offered propulsion systems are as follows:
• TMotor U8ii in a Quadcopter Configuration with folding FA28” Propellers
• TMotor U8ii in a Coaxial X8 Configuration with folding FA28” Propellers
Each propulsion system consists of a motor, propeller, ESC, carbon fiber tube, and mating
bracket. Each propulsion system is hard-coded to work in only one socket location: Front
Right, Front Left, Back Right or Back Left. Only the Front Right propulsion system can be
inserted into the front right socket, and only the back left to the back left, etc. The user can
verify that the propulsion system is inserted in the correct socket by going to PRISM menu
page in the WattsQGC (See Chapter 7, section 7.11.2, subsection II).
PRISM’s features a patent pending technology which is called Propulsion ID. Propulsion ID
allows the user to insert any type of propulsion system that Watts Innovations produces
into the aircraft, at which time the drone will automatically understand which propulsion
system is connected, and then automatically load in the parameters that are necessary for
flight for that particular propulsion system. In layman’s terms, this allows a user
