Required components
The section covers a list of required components, along with recommendations to get your frame ready
for flight. RC Transmitter and Receiver options are not discussed but obviously required.
Flight controller
The frame is designed to accommodate a variety of flight controllers. The X pattern mounting
grooves will self-center as long as the controller mounting holes follow a square pattern. A
controller of up to 51mm may be used including the very popular and user friendly KK2.0 series.
Recommendations: Naze32, Witespy Flip series, KK2.0+ series, CC3D
Motors
Four motors are required. The arms will accommodate 1800 to 2200 series motors that use an
M2 – 12mm to 16mm or M3 – 16mm to 19mm bolt pattern.
Recommendations: RCX 1804-2400KV, SunnySky X2204-2300KV, T-Motor MN18042400KV, T-Motor MN1806-2300KV, T-Motor MN2206-2000KV
ESC
Four Electronic Speed Controllers are needed, one per motor. Generally speaking, any high
quality ESC that matches the motor’s current requirements will work.
Recommendations: 10A to 12A, under 12g weight running multirotor firmware such as
SimonK.
Propellers
A set of four 5x3, 2-blade or 3-blade propellers, in two Clockwise and two Counterclockwise
configurations.
Recommendations: Gemfan 5x3, HQ 5x3.
FPV camera (optional)
A high quality CCD Sensor based board camera with “WDR-Wide Dynamic Range” is your best
choice. The included FPV Camera mount is designed to house the very popular 600TVL Sony
Super HAD camera, commonly referred to as the “Sony PZ0420”. The outer “snap-off” frame will
need to be trimmed from the camera board to fit the included mount. Other cameras that use a
similar 32mm board size with M2-28mm bolt pattern should also fit but have not yet been
tested. An FPV camera is not required for sport line of site flying.
Recommendation: Sony PZ0420 CCD Camera
Recording Camera (optional)
The included vibration dampening camera platform allows for mounting a high definition
camera that you can use for recording and playing back your flight. Motor and propeller
resonance can negatively interact with a CMOS based camera to create a shaky video artifact
commonly referred to as the “Jello Effect” The floating mount is designed to eliminate the
“Jello” effect without having to deal with tedious and painful motor and propeller balancing. If
you are experiencing vibrations in the video, you are likely dealing with a damaged motor and /
or propeller. The platform is designed to fit the very popular Mobius HD camera. Other small
and light cameras may be used as well. A recording camera is not required for sport line of sight
flying.
Recommendations: Mobius HD, Keychain 808 series
FPV Video Transmitter (optional)
Standard full size video transmitters may be used. Specific choices will depend on user
preference and equipment compatibility. An FPV transmitter is not required for sport line of site
flying.
Recommendations: 5.8GHz offerings from Fatshark, Immersion RC, and Boscam
Battery
A 3S Lithium Polymer (LIPO) battery in the 1300mah to 2200mah range is recommended. Due to
the light weight design of this frame, diligence exercised in the component selection and
assembly will be rewarded with long flight times. Always pick the lighter component and keep
the wiring short and tidy. Every gram counts. Clearly every setup will be different, however
generally speaking a 1350mah battery should yield 6-8 minutes, while a 2200mah should yield
10-13 minutes of flight time.
Recommendation: Standard 3S 2200mah battery
Assembly
The intent of this section is to show general assembly and mounting of components with examples. The
order will depend on the user’s preference.

Landing pegs
Four optional landing pegs are included in the kit. They are helpful for taking off and landing on short
grass without having to use a flat platform. The pegs are designed to insert and snap into place without
glue or screws. Installation is a little tricky so the recommendation would be to install them prior to
mounting the motors if you plan on using them.
Insert one leg into the mounting slot on the bottom side of the arm. While holding the first leg in the
slot, pull on the second leg to align it with the second slot and insert. When fully inserted the peg should
be fully seated in the arm.

Mounting the motors to the arms
The arms provide recessed mounting holes for the motor screws allowing you to use the included
screws with your motor of choice. The other holes are if you prefer to use longer screws and to allow for
multiple orientation options. Note that a long screw that protrudes into the motor windings will damage
the motor. The recessed mounting holes are designed to take the guess work out.

Mounting the arms to the base plate
The arms attach on the bottom side of base plate. Each arm is attached using the 4 M3 screws and lock
nuts on the outer four holes and using two M3 nylon screws and posts on the inside two holes as seen in
the images below. Rotate the arms around if the center cutouts on the base plate don’t match up with
the arm.

Attach the remaining posts with nylon screws to the bottom plate. 10 posts in total.
Installing the vibration dampening camera platform
There are two options available for installing the recording camera platform. The first option is for the
user that plans to use a separate FPV camera in addition to the recording camera this is the conventional
setup since CCD cameras tend to have better live video out capabilities with reduced time lag. The
second option is for those that want to use the recording camera for FPV as well by utilizing the live
video out option from the camera. For the latter option, the camera platform may be mounted inside
the frame for a cleaner sleeker setup.
Option 1 – Separate cameras for FPV and recording.
Install the three included rubber grommets inside holes from the top side of the top plate. To install,
gently pinch the grommet and work the flange inside the hole until it’s seated. The flange should
protrude and sit flat through the other the side of the plate. Be careful not to damage or tear the rubber
during the installation. Install all three grommets on the top plate then work the top flange of each
grommet through the holes in the camera platform.

Installing the FPV camera
This example is given using the popular PZ0420 camera. Remove the outer PCB ring and attach to the
included mount with M2 screws or double sided tape.
Mounting the FPV camera to the mount
Both the base plate and top plate have slots where the FPV cam mount fits snuggly.

Option 2 – Single camera for FPV and recording. Mount the platform on top of the frame.
If you will be using the Mobius or equivalent for FPV you may want to setup the frame using this option.
The camera platform will mount on the underside of the top plate rather than the top. Use the same
holes for mounting the rubber grommets.

Installing the flight controller
The flight controller mounts in the center of the frame on the base plate. The mounting slots offer great
versatility and will self-align any controller with a square screw mounting pattern. Eight Male/Female
standoffs are provided. Four will be used for mounting the flight controller, the other four can be used
for stacking a power distribution board. In this example, we are using a power distribution board. Use
the shorter 8mm Nylon screws for mounting the standoffs to the base plate. If using a distribution
board, you should solder your ESC power lines to the board prior to mounting the controller to avoid
damaging the controller via the soldering iron.

Installing the Electronic Speed Controllers
The ESCs can be mounted strapped to the motor arms as typically seen on many installations.
An alternate preferred option is to attach them to the underside of the base plate using high quality
double sided foam tape or zip ties. Using the latter option will add small improvement to the overall
efficiency by taking the ESC outside the propeller air flow path.

Antenna extension mount
The top plate features a mounting hole designed to allow the user to install an SMA connector extension
between the FPV video transmitter and antenna. Doing so will take relieve the transmitter from possible
damage in the case of a crash as opposed to mounting the antenna directly to the transmitter.
