nose

STEP 1

Glue the “nose”, "fs1", “fs2”, “fs3” and “fs4” in this order using CA glue. You need to insert the “pim” part gluing the “fs4” to facilitate assembly. Other parts have their inserts already.

Apply glue to the insert surface and assemble the model parts. Avoid spraying the accelerator to insert surfaces without assembling the model parts. This can cause the CA to dry fast while you try to assembly the model part.

Have a napkin with you and distribute the overﬂowing

adhesive onto the joint surface. This process will strengthen the model. When spraying directly on CA, do not be excessive and spray from a distance.

STEP 2

Install all your electronics to the fuselage before gluing the wings. Insert the Ø5x360 mm CF rod. Prepare the Spinner by gluing the “spinner_base” and “spinner_adaptor” parts together. Then you can install the "spinner_cap" while assembling the propeller.

Insert your servos according to the direction as shown on the model.

STEP 3

Glue the “lock_body” part into the “hatch1”. Assemble the “lock_catch” part by using m3x8mm imbus bolt.

New Craycle FPV Cam and VTX mounts allow you to mount any FPV system in the market. You can adjust the camera

position and ﬁx it with a 2 mm screw. You can mount any FC

with its 10x10 to 35x35 mm VTX mounting holes on the bracket

or stick with double-sided tape. You can also use zip ties to ﬁx

the VTX to the mount.

You can use a soldering iron to drill Hatch for FPV Antennas.

STEP 4

Test if the "wing_r1" and “wing_r2” parts ﬁts together

comfartably and reassemble by gluing the insert surface.

Spread the overﬂowing adhesive by wiping it along the joint

line. This way you will get a stronger wing. Make sure the wing parts are sticking in a straight line.

Now you can break the aileron from its tiny connections and re-assemble them using CA Hinges. Then you can glue the “wing3” part to its place. Avoid using excessive glue and spray on the hinges. The same process goes for the other wing.

STEP 5

Now you can assemble the wings to the fuselage. Be careful to

not apply glue to under the aileron/elevator ﬂaps.

You don’t have to apply glue to the CF rod. CF Rod will be guide for the wings and spread the forces to the fuselage without gluing. This way you can use it again. But if you want to push limits with this model, better you apply glue to the CF rod. This will make the model more rigit.

Make sure your servos is centered and the servo arms are 90 degree as shown in the image above.

Glue the “horn” parts and assemble your pushrods. Then you can assemble the “servohatch” to the wing.

Now you can glue the “vertical” parts to the fuselage!

Epilogue

You can add extra weights into the “fs1” to make CG is correct. For Orca, CG is more important than the other models since its

a ﬂat ﬂying-wing model. Once you get CG right, model will ﬂy

perfectly stable.

Make sure the model is a little bit nose-heavy for the maiden

ﬂight and give 1 mm elevator trim up. If you think the model ﬂies too fast, cosider to move CG a little to the back.

You can print this model completely with LW-PLA to make it

slow ﬂyer but it’s not necessary at all. Regular PLA will be

enough thanks to its new design approach. You can also prefer PetG to make the model heat resistant at summer.

We recommend 6” propellers for this model but can also use a

5" propeller to ﬂy even faster with 4S lipo.

Epilogue

www.craycle.com

We developed this model as a compact freestyle FPV model to

experience the best FPV ﬂight with a small plane. With Orca

V3, the model became nose longer, lighter and user-friendly in electronic setup. So this model can also be used as a long-range autonomus plane with the Craycle E-brackets for FC and GPS components and the brand new FPV Hatch.

We update our models according to user demands and share them free of charge to previous owners. If you see something that is gonna be improve your user experience on this model, please join the Next Model Survey on craycle.com.

Print Guide

We have prepared printer proﬁle on Cura Slicer for you. If you

have a Marlin XYZ type printer, you can print directly with provided gcodes as well. If you can’t use the gcodes don't worry, just follow the instructions...

1) Go to the Cura Proﬁle Article to download Cura V4.13.1 and import craycle.curaproﬁle.

Article: https://craycle.com/craycle-cura-proﬁle/

2) Change this settings according to your printer:

- Material Settings.

Nozzle Temperature Buildplate Temperature

Flow (wall ﬂow is important!)

- Travel Settings.

Retraction distance Retraction speed

We make internal supports by creating gaps in the model parts. So, the "Slice Gap Closing" value should be 0 mm or closed.

Turn off all gap-ﬁlling features in the slicer.

You should print the biggest wing part of the model to test your printer. Make sure the wing weight is equal to the settings table! Then you are ready for the rest of the model parts.

This process will both verify your extruder ﬂow and verify your

printer settings correctly. If you have mechanical problems on your printer, you will also see that mesuring the model weight.

We pre-routed the model parts for you but still make sure the model parts are oriented at 45 degrees to the bed. This way X and Y axis works coordinated and you can get maximum surface quality. You can also set the Z seams to corners.
