SCARAB HEXiikopta Airframe The following is the recommended building tips for assembling the airframe.

HEXiiKopta SCARAB is designed for 10 amp ESCs x 6 - preferrably running 4S 775kv Motors between 35g - 75g Wires - 20AWG wires LiPo 150-220g 4S 9050Triples guide VERSION 2.0.1

SCARAB is designed to sacrifice the frangible booms in the event of a crash and save the motors,electronics and the mainframe from impact G forces. Thin rounded booms are very streamlined to prop wash and gives longer flight times of 12-15mins. We expect the removable boom to be used in most cases - for travel and for modular replacement reasons. good connections are vital. If a single connector fails or comes loose - your Hexii may crash - double check each one wiring - decide if you want removable booms/plugs. or if you want to solder the wires to the ESC? Solder wires cannot come loose - but can be less suitable for Travel-AP - so each pilot takes his own Risk. All wires must be checked before each flight. If you crash - never fly immediately. Inspect all wiring very carefully. Balance props perfectly on a magnetic balancer. then dynamic (running ) balance them. Mounting - medium/ large Motors (55-80g) mount below the boom centreline to counteract gyroscopic forces - see sample at left. The strength of the v2 mount comes from the composite of carbon and aluminium together - Attach the motor to the composite mount (left) - use Loctite on the screws and also on the shaft lock screw. Use a diamond file or blade to debur (bevel) the inner edge of the boom - Slide the carbon boom over the completed assembly including the wires - be sure not to cut the wires on the carbon shaft ! Composite structure - Bond the two parts of the engine mounts - use baking paper on the work surface - Parts comes pre-press fitted - using a thin-nozzle aplicator apply lines of thin Cyno on each of the 4 sides of each mount Thin Thin and allow to wick-in. Allow to dry CYNO CYNO fully - do NOT insert the mount while superglue is wet. Wait 24 hrs if you Thin Thin CYNO do not have accelerant spray. If using CYNO Accerant spray wait 10 mins to allow it to soak fully into the fibres first.

THIN Cyno-acrylic glue (HobbyKing superglue) ALL 3 x 20awg wires fit inside the carbon boom (right) - Now in v2 - the red lock (below left) secures the holder in combination with the Carbon inserts - Start by soldering the bullet connectors to the long wires on the CarbonBird motors. For CarbonBird use 8mm flathead bolts (not Included)

use a blade or a diamond file to bevel the shaft(below) - this will prevent the wire insulation from being cut when fed over (right)

V2

each motor exit wire location is different - study each motor choose the mounting holes which allow the wires to go directly into the boom - use two matching holes in the engine mount by aligning the wires to the shaft side of the key shape - Attach the motor - use Loctite on the screws and also on the shaft lock screw. Slide the carbon boom over the completed assembly (below) including the wires - be sure not to cut the wires on the carbon shaft !

20AWG wire 2 wires one side - 1 wire on the other side care not to pinch the wires

tighten the screws alternately in stages - take care to keep the saddle even and the gap identical on both sides NOTE : The lock compresses down onto the insert balance each motor with a zip tie - test run - should be 100% silky smooth - rotate the zip tie for best results

V2 Boomholders - The Centre hole on the top of the boom holder LOCKS the boom position - use a 6mm grub screw with Loctite (left and right) - tighten lightly - final tignening after settng the rotation angles on the front booms are set to 3° below - too tight will damage the CF tube inside - the 8 screws hold the boom - the grub screw locks the boom

Make a power distribution lead - 5 wires (the fifth wire will be for LEDs/ BEC supply)

use a piece of heat shrink to hold the wires - then solder so it can fir inside the XT60

use a piece of heat shrink to hold the wires - then solder so it can fir inside the XT60

slide some 5mm heatshrink onto the multi’s before you solder the posts - note that the temporary heat shrink is then removed - before sliding the final 5mm down

finished power lead - the LiPo will have the male connector - shown for clarity here

Learning the Throttle curve - After setting your Tx to 1095/1500/1905 in the GUI - do the ESC throttle learning curve - To calibrate the ESCs as a group build a multi harnes - a Y lead - then connect the actual Rx, one engine - with Throttle at full on the Tx then connect the ESC wiring loom - after two beeps reduce the throttle to idle - 3 or 4 beeps (3S or 4S) then power off everything. Done

install the metal posts to one plate - leave them fairly loose. slide the blue holders down and clip them in place - they are not symetrical - there are left and right halves! - then the ESC and the 2mm female connectors - use FLUX paste to ensure you have a good solder join version 2.0..1

fit the six boom mounts to the lower side - 3 of the mounts use the longer 2*10mm screws to suport the landing gear - fit these finger tight only - the front landing gear goes behind the front booms Page 4

The holders will only fit one way - DO NOT TIGHTEN yet - then lower the blue (or red) holders in place over the posts. Loose only.

After installing the 6 10amp ESC - then install the SWITCHING uBEC (piggyback ESC are suitable for connecting is large series connections as they can overheat the 7805 chip linear BEC )

Gear - you can install it default or cut it shorter. use the 10mm M2 bolts and be sure to use the SCARAB TOOL 1.57mm washer are used here but are not essential

NOTE : SS M2 button heads have small shoulders and can strip with a M1.5 hex - be sure to USE the 1.57mm L HEX provided in the kit 1/16th “ inch

use the 5mm standoffs for PARIS then the 15mm or 20mm for the top deck

You need either a sum Receiver or a SUM encoder to run six engines on a PARIS in 1.9 - The PARIs software can be set to use PINS Cm1 (engine5-rear) and Cm2 (engine6 front)

MOTOR tilt - we designed the SCARAB system to use motor tilt - this gives positive YAW control for Aerial photo Ops with very little RPM change required - ALSO allows the pilot to trim the neutral YAW position in hardware - not on the Tx.

Go Pro - You can carry 2 x GoPros(not included - custom mount shown) - we recommend 720p/60fps. - keep the mount very firm with NO PLAY - Balancing props an dengines dynamically is essential to removing the Gello Effect of the rolling-shutter CMOS chip in the GoPro - new firmware in GoProHD v2 also helps with Gello elimination.

1.578mm 1/16” L tool ; or SCARAB frame TOOL NOTE : do NOT use 1.5mm metric heli tools !

NOTE : Carbon can block 2.4Ghz RF run your Rx antenna well clear of the carbon plates - do a range check! LiPo - we recommend a combo of Velcro and the strap - Use a Quannum Telemetry cell monitor to land when the first LiPo cell is 4.2->3.3v - total voltage is not as good - as one cell goes down first!!. version 2.0..1
