Mini Quad FPV Camera Easy Mounting

Author: Oscar.

Mini Quad FPV camera mounting.

It’s always tricky how to mount your FPV board camera on the mini quad frame, especially as you fly faster, the more angle tilted the camera needs to be.

Solution: I use material that is widely available, 2mm zip ties, nylon spacer, and vibration dampening balls. As the balls are elastic, and can be squeezed, we can adjust the zip tie to make whatever angle we want.

In fact, as you progress, you can actually go back, and close the zip tie a bit tighter to achieve a larger angle, so you don’t have to replace anything.

Someone also suggested to use sticky foam to replace the vibration balls and spacers.

Propeller Sorting

Author: Oscar.

Everytime the propellers arrive, I sort them out, label them, and put them in two separate bags which are also labelled.

I labelled the props with 1 and 2 with a pencil, 1 being rotation CW and 2 being CCW rotation. I know there is rotation letter such as “5030” and “5030R” printed on the props. But when you are under the sun, a big “1” and “2” is much easier to read than the tiny print, which is the same colour as the props!

I also put them in bags, so when I get to the field, i can immediate identify what props go where.

3D Print ZMR250 Arm Spacers

Author: Szi Mi.

Simple but useful trick to hide the distribution board and the ESCs QAV250 frame. 3D printed spacers make 10 mm space between the 1st and 2nd level to hide all electronics.

As you can see there is a lot of space in the frame for the FPV, camera, etc…
(this is a ready to fly quad – the controller, ESCs, motors, distribution board and the receiver already installed)

Recycling Cables and Spray Bottle Plastic Tube

Recycle – Household spray bottles are a source of plastic tube for standoffs/ spacers/ antenna protectors.

How to Mount Vibration Dampers – The easiest way!

DIY GoPro/XiaomiYi Camera protective Case

Use recycled motor packaging (in this case i used Cobra 2204 motor foam). The foam needs to be able to fit the gorpo in there. Cut some holes for the USB connection and SD card, also for the record button.

But an extra piece of foam to cover the LCD screen as well. And it also works well as a camera damping system as the foam absorb some vibration.

Use Antenna extension lead to protect your VTX

I see some people report problems that they ripped the antenna holder off the VTX, along with the solder copper pads, which is irreversible, very very difficult to fix.

Best way to prevent this from happening again, is to use an antenna extension lead, fix the other end on the frame so it takes the impact in a crash, and not the VTX antenna connector.

    Hi

    I’ve ordered my ZMR250 V2 frame with PDB V1.03 and as this is my first quad and first build, I like a few advice.

     

    I would like to know if you have the layout or manual for the PDB board. As I’m going to fly with 3S 2200mah lipo, could you give me some basic advice on this build?

    Also I want to know if the 5v and the 12v on the PDB will have power from the lipo battery.

    Much appreciated for your kind assistance.

     

    The following is my setup. ( Please advise if something is wrong )

    Each SMA connector introduces approx. 3dB of loss. It would be better to solder the extension right to the VTX.

    Thanks for posting these tips, great stuff! Could you expand a bit on which specific parts to order (like names at least) besides the VTX extension cable that allow you to screw it down to the frame? I don’t think everything necessary is generally sold together and I’m having trouble googling up the right parts.
