Landing guards of crazyfile do not fit firmly

[Saswati-Project]

I recently bought a Crazyflie 2.1 Brushless, but I'm unable to securely attach the landing legs / landing guards to the drone. I followed the tutorial, but even with a slight shake, the landing guards fall off.

I'm not sure what I'm doing wrong or how to attach them more firmly.

The following pictures show the landing guards and how I attached them.

Also, where should I attach the AI Deck? Should I mount it above the battery or on top of the Flow Deck?

Hello @Saswati-Project!

To properly mount the propeller guards, you need to push them until they snap on the leg of the Crazyflie Brushless, as you can see in this image.

Regarding the AI deck, you can mount it either above the battery, or on top of the Flow Deck. Note that if you want to mount it underneath the Crazyflie, you need to use the long pins that are shipped with the AI deck.

Let us know if you need anything else.

Thank you for your reply. Is there a specific technique I can use for snapping it? The board looks very fragile, and I'm afraid to apply too much pressure to it. If you have any videos demonstrating this, other than the tutorial you already shared on the official website, could you please send me the link?

I tried several times, but I wasn't able to fix the propeller guard. Can I fly the Crazyflie without the propeller guard?

Sorry for your issue with the guards, we're aware that the guards are now a tighter fit in the latest batch, and we're currently looking into the issue. We got a tip from another user that an easier way to do it is with no motor mounted, turn the PCB upside down and wobble the arm into the guard tips.

It is not recommended to fly without the propeller guards or landing legs attached. Nothing will stop you from flying without the guards or legs, but if you accidentally crash the Crazyflie the PCB is not protected and will hit the ground directly. Do you have the same issue with attaching the landing legs instead of the propeller guards?

Let me know if you still have issues and we will figure out another solution!

Thank you for the answer. Even if the motor is not mounted, it is still difficult to attach. Do you have any video guides that show how to do this? Could you please share them?

The video is very helpful, and I was able to attach the propeller guard. I would like to add one tip for anyone who has the same problem I had.

Don’t just follow the video by removing the motor and trying to attach the guard—also pay attention to how the person holds the board. In particular, they use one finger to support the extended part where the motor needs to be attached, while positioning the other three fingers underneath the board. Holding the board this way makes it much easier to attach the propeller guard.

After attaching the propeller guard, it can be difficult to insert the black screws. One suggestion is to start with the top black screw, but don’t tighten it completely. Leave it loose enough so that you can make small adjustments to the motor. Then insert the other two screws and leave them loose as well. Once all three screws are in place and everything is properly aligned, tighten them firmly.

I went through this experience myself, so I wanted to share this tip in case it helps someone else.

Great to hear that you managed to attach the propeller guards and thank you for the suggestions!
