92 5mm*50mm Aluminum Bolts

92 5mm Aluminum Hex Lock Nuts

8 3mm*21mm Nylon Threaded Spacers

1 Flight Controller (I used the APM 2.5+)

8 ESCs (I used HobbyKing 30Amp Multistars)

1 ESC Programmer card

8 Motors (I used Turnigy Multistar 4822-690Kv 22pole Motors)

6+ 10CM Male to Male Servo Leads

2 HXT 4mm Connectors with Protectors

24 Male 3.5mm Bullet Connectors

40 Female 3.5mm Bullet Connectors

A lot of solder and heat shrink


Creating Motor Extension Wires:

-Start by cutting the 14AWG wires to length so that you have 8 sets of 3 wires that are long enough to make it from your motor through the 500mm tube to your ESCs once hooked up (actual measurements to come).

-Solder on one end of each wire a female 3.5mm bullet connector and on the other end a male 3.5mm bullet connector.

-Heat shrink the connectors.

-Connect female ends of the wires to the motor and wrap in electrical tape to prevent them from coming lose.


Building Motor Mounts:

-Start by putting the 5mm*50mm bolts through the appropriate holes as this will be difficult to do once the motor is mounted.

-Mount motors with 3mm screw provided (in my case the screws provided were too short and I had to use longer ones.  Updated measurements to come.)

-Slide 4 tube mounts on accordingly.

-Thread nuts on so that the assembled mount can slide around the carbon fiber tube but tight enough that they will stay in place.


Building Wiring Harness:

-Start by cutting up 8 4in sections of the red 14AWG wire and 8 4in sections of the black 14AWG wire.

-Cut 2 8in sections of the 12AWG red wire and 2 8in sections of the 12AWG black wire.

-Cut 1 6in section of 14AWG red wire and 1 6in section of 14AWG black wire.


-Using your best MacGyver skills create a Y shape with the set of 6in 14AWG wire and the two sets of 12AWG wire at the bottom twisted together black to black and red to red.  Then twist the top half together out of the sections of 14AWG wire.  Using some spare single strand copper wire wrap everything tight together keeping the red to the red and the black to the black (DO NOT CONNECT BLACK TO RED UNDER ANY CIRCUMSTANCE).

-Apply liberal amounts of flux.

-Apply liberal amounts of Solder until you feel as though there is no way that the wires will ever come apart.

-Solder on female 3.5mm bullet connectors to the 14AWG wire.

-Solder the 2 HXT connectors to the 2 sets o 12AWG wire (check polarity).

-Solder connector of your choice to 6in 14AWG wire to provide accessory power.

-Heat shrink everything.


Building the Center:

-Start by attaching the ESCs how you would like them to the top plate.  If needed drill extra holes for zip ties.

-Go ahead and mount the equipment rail by using 4 5mm bolts, 4 lock nuts and 4 tube mounts.  Mount pole centered on bottom center plate.

-Run 5mm bolts through all holes that are to be use on the top plate.

-Slide 32 tube mounts onto 5mm bolts to allow for the tubes to mount.

-Slide on bottom plate.

-Put a lock nut on each bolt and tighten just tight enough that the tubes can still slide in.

-Attach ESCs to wiring harness.  Red to red and black to black.


Assembling Legs:

-Fill 3 of the plates with 5mm bolts.

-Slide on 8 tube mounts per plate so that the tubes can be mounted. 

-Slide on other side of the plate.

-Put on lock nuts and tighten so that they are loose enough for the tubes to slide in and out of.

-Slide leg mounts on 3 of the motor tubes and angle so that they are 6 inches from the motors as well as pointed down away from the motors with the angle of the bracket pointing outwards. (A picture will help this.)

-Slide poles for legs into brackets and tighten whole bracket.

-Slide leg ends onto tubes and glue on if needed.


Attaching Arms:

-Start by sliding in your 3 motor tubes with the landing gear on them.  Put one in the back and the other two on the sides.

-Slide in other arms keeping an eye that motor orientation is close to straight up (We will align these later).

-Tighten all bolts on center to lock in arms.  Make sure while tightening each arm that the tube is flush with inner most side of the inner mount.

-Align motors.  Make sure all motors are level with the top center plate.  This can be done with a level.

-Tighten all motor mounts.

-Attach motor wires to ESCs.


Equipment Level/Flight Controller:

-Mount your flight controller on the equipment level using a layer of double sided foam backed sticky tape then Sorbothane then another layer of double sided sticky tape.

-Wire up your flight controller to the ESCs (check order of wires on manufacturers web site) and to your receiver.

-Wire power to your flight controller from the extra connector you put on to the wiring harness if needed.

-Wire in any accessories such as telemetry or OSD.

-Mount to center by using the M3 Nylon hardware.


Pre-Flight Checks:

-Make sure that your ESCs are calibrated correctly.  Refer to the manual for your ESCs and for your flight controller.

-Check motor direction.  If motors are going the wrong way, swap two of the motor wires that attach to the ESC.

-Mount Propellers and charge batteries.

-Calibrate level and other settings on flight controller.

-PID settings for APM 2.5+ will be coming in the next few days.

-Make sure nothing is loose.


Flight Tests:

-Lift off and keep the VPAS 8 about 10 feet off the ground.

-Does it twitch or act sluggish?  If so adjust your PID settings.

-Once you are able to keep steady flight test your auxiliary components such as GPS.
