In this article, I am going to show you How to Scale your Craycle Plane with simple steps. We were tested to scale our first model FPV Orca and want to show you how to do it easily. This is our first scaling test with FPV Orca V3 and CraycleCub V2.

How to Scale Your Model?

• You can scale up or down any Craycle Planes in the same way.
• The important thing is the nozzle diameter. When you scale the model, the walls we modeled as 0,8mm which are supposed to be 2 walls with 0,4mm nozzles will be thicker or thinner.For example: If you scale the model to 125% on your slicer, the 0,8mm walls will be 1 mm. When you slice it, you will see 0,2 mm gaps between walls since your nozzle is 0,4mm.
• The solution is scaling the nozzle at the same ratio as the model! So if you scale the model at 125%, you should also scale the nozzle at 125%, then the nozzle will be 0,5 mm and the gaps will disappear on the 1mm walls. This is what we need.

The hard thing is changing the nozzle on the printer, right? But I didn’t do it!

I only changed the nozzle on the slicer but I didn’t made any physical changes. So the slicer prepared the flow and paths according to the 0.5 mm nozzle. When we use the 0.4 mm nozzle with this prepared g-code, there is a high amount of filament flow from the nozzle, I increased the nozzle temperature by 5 degrees to relieve this and I did not experience any problems other than feathering. You can see the surface quality.

Let me get straight!

• Scale up the model to any size you want (Consider finding the same scale CF Rod)
• Scale up the nozzle at the same ratio as the model
• If you are not changing the nozzle on your printer, increase 5 degrees of nozzle temperature.
• If you scale 150% or more, better if you change the nozzle on the printer as well but I recommend you try without changing the nozzle first.

If you scale down, you don’t need to change the nozzle at all Scale down is also interesting, you can make Craycle Planes under 250 grams.

What about the Electronics and Mounts?

When you scale the model, the servo and motor slots also get bigger. Since the motor mount has a slot design, it fits bigger motors when you scale up the model, but I have designed motor mounts for 125% and 150% scales so that you can use the same or similar size motor.

We had to design an adapter for the servo. It’s a very simple design, but it saved us from gluing the servo. If you scale down the model, you may have to glue the servos. Using Hot Glue while gluing makes it possible to remove it later. It’s hard to scrape the CA.

This is a single design that fits 125%, 150%, and 175% scale models for servo mounting.

FPV Cam Mount, VTX Mount, Lipo Mount, FC Mount?

These mounts have no problem with scaling the model at all. You can figure it out to mount them with scaled or regular versions.

For the FPV Cam Mount and VTX mount, I have used the regular size mounts easily using their mounting holes and a little Hot Glue:

Since you have more space, it was more comfortable to place the FPV system and lips together in the model. Everything was easy and fine.

I scaled up the lipo mount with the model and glued it to its place.

We have a lot of electronic bracket options which is common for Orca V3 and Discover. I have scaled one of them and mounted the FC with its regular-size mount so I can replace it with another regular-size model easily. There are tons of options here and you are free to find your way to mount your FC.

Important Note: This method is only recommended for Craycle Planes. To provide this, we have been working for a long time to make the models with the same design approach and updated them all several times to make them similar. We can’t guarantee that this method also works for other models in the market. I hope they will also work on it. It is a game-changer technique for 3D Printed Planes!

That’s all! Now you can scale your Craycle Plane at any size you want!
