nose

STEP 1

Glue the "lipo_mount" part to "fs2", then glue the "fs1-nose-fs2-fs3" parts together using CA glue. You can insert the “craycle_pim” parts into their slots on the fuselage parts to facilitate assembly.

Avoid spraying the accelerator directly onto the CA glue! Spray

on ﬁrst piece and wait for 15 seconds to dry it. Then you can

aply glue on the other piece and put the pieces together.

Note: Avoid excessive use of glue.

STEP 2

Glue the "fs4" - “elevator_r” - “elevator_l” parts together. Make sure that the elevators are 90 degrees to the rudder.

Carefully glue the “elevatorbar” part into the slot under the elevator parts. The elevator bar will distribute all the force to both sides.

It’s okay there is a small gap between elevator_r and elevator_l. The elevator bar will handle the mechanism. Please avoid the excessive usage of glue.

Carefully use sprey accelerator on this step. Avoid spraying the

hinge slots. This makes hinge installation difﬁcult.

STEP 3

Release the elevator ﬂaps from the elevator by breaking it’s tiny

connections.

Reassemble and glue the ﬂaps using TPU hinges or CA hinges

that you prepared by using Hinge Maker Tool (Available on craycle.com).

Note: The CA accelerator sprayed to stick the elevator may have contaminated the hinge slots! Take your time, apply the glue

onto the hinges one by one and insert into the slots on the ﬂap ﬁrst.

STEP 4

Glue the "rudder1" and “rudder2” parts together by inserting “cub_pim”. Glue the rudder you prepared to the tail by inserting hinges into it’s slots.

Note: The CA accelerator sprayed to stick the elevator may have contaminated the hinge slots! Take your time, apply the glue onto the hinges one by one and insert into the slots on the

rudder ﬁrst.

STEP 5

Clean the little “ruddergear” parts and glue them onto the slots on the rudder. Assemble the “wheel20_rim” and “wheel20_ring” parts to get the rear wheel.

Assemble the rear wheel to the rudder gear by using a 2 mm steel rod or something similar. Glue the steel rod carefully without applying glue to the wheel. You can apply some liquid oil to make the wheel turn easily.

That's it! You have a rear landing gear with the steering system.

STEP 6

Release the aileron ﬂaps from the “wing2” by breaking it’s tiny

connections and reassemble the aileron using CA hinces.

Take the servo as position as the same in the image below and screw onto the “wing1” part. Then you can glue the “wing1”“wing2” and “wing3” parts together. Be careful not to apply glue to the servo and same process goes for the other side.

Ø5x170 CF Rod

fs_support

STEP 7

Mount the Wings to the Fuselage with CF Rod by inserting the servo cables. When gluing the second wing to the fuselage, you should attach the "fs_support" part to the CF Rod. In this way, the fuselage width will be preserved. The "fs_support" part should be glued to the fuselage to prevent the fuselage from stretching. Apply a minimum amount of adhesive to the CF Rod to be able to reuse it.

Stick the tail that you prepared to the fuselage by inserting it’s slot to facilate assembly.

STEP 8

In this step, take your time and do it right!

You need to be sure the wings are holded in a straight line

(Hold the model upside down on the ﬂat table).

Then you can screw the “wingsupport” part by using 2 mm screws (Servo mounting screws) into the holes on the wings and fuselage.

When assembly is complete, turn the model over and check

the ﬂatness of the wings.

Assembly

STEP 9

Install your servos to the fuselage and prepare 2 pieces of 1,2 mm pushrods which is approximately 210 mm length.

You can make Z bend for the both side or use rod linkage to

make detachtable and facilate to set the ﬂap positions.

For this model, the best way to mount the push rods is; Z-bend is mounted on the outside, the push rod connectors are mounted on the servo arms inside. In this way, connectors are installed quick, it becomes possible to deassemble the wires, and the objects that will create drag are reduced on the outside.

You can use cheap 9 gram servos for this model becouse of it's not required high sensitive on the control surfaces.

STEP 10

Prepare quick release landing gear by using 2mm steel wire. You can use this page by printing as %100 scale and also you can use the dimensions as mm.

Assemble the “wheel35_ring” and “wheel35_rim” parts together and install them onto the landing gear that you prepared (You can make a clear hole in the “wheel35_rim” by drilling it with 2 mm drill bit.)

Glue the “spinner_adaptor” and “spinner_base” parts together by inserting 5 mm rod to make it centered. Assemble the spinner, motor and landing gear as shown.

STEP 11

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

Epilogue

www.craycle.com

You can also prefer the Hatch1_ﬂat and Hatch2_ﬂat to make to model real scale if you ﬂy without FPV. Use 2 mm screws to

mount Hatch2 and drill before screwing.

You can add extra weights into the “fs1” to make CG correct. With Cub V2, CG is way easier to set correctly than before.

Make sure the model is a little bit nose-heavy for the ﬁrst ﬂight.

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

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

enough thanks to the new design approach.

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

7" propeller to make it model ﬂy slower.

13

Epilogue

www.craycle.com

We developed this model as a compact Super Scale model to

experience FPV ﬂight from the real pilot's perspective. With V2,

the model became even lighter and slower. So this model can also be used as a Trainer.

Enoy with free upgrade with CraycleCub V2! Please check update notes on craycle.com.

We are always continue to improve the model after published. Usually this happens becouse of requests. If you need some feature 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.

Print Guide

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.
