Just to show my first build and perhaps get some feedback
I'm totally new to this hobby and never flew a quad before.
I used a spacer to fit all the electronics in the lower part of the quad and give it a clean look at the top.
Also lowered the top plate incl. fpv cam. 
To be honest, i like the ZMR250 frame, but the whole quad is a bit on the heavy side (655g incl. props, 1800mAh nano-tech).
Are there any recommandations to reduce weight?

it's just a heavy frame IMO
but to reduce weight, you can try:

- use Nylon standoffs (that's 5-10g)
- use aluminium bolts and nuts rather than steel (I saved 15g doing that on the other quad)
- use 1500mah lipo rather than 1800 (that's probably 20-30g there?)
- no landing gear (save you 10 to 20g)

Thanks for your reply, Oscar.
You are right, those steel bolts are heavy...is it a good idea to switch to nylon bolts to hold the arms?
I've just ordered a 1300 graphene lipo (not the lightest i know, but it would be a nice fit to my black quad)

How did you make that gap between the two bottom plates? The pictures I've seen of the ZMR250 and the two bottom plates are much closer. I think it's a really good way of hiding the wiring.

Nice build by the way.

wow!!! that thing is awesome, I love the bottom plate mod.

That looks sexual 

If it was mine id put some really bright coloured props on it now to finish it off.

Thanks HamsterFPV I've bought a 3D printed spacer (btw it is really great quality print with a nice smooth finish) and put it inbetween the two plates.

This gives me space to fit the PDB and all of the wiring in. To lower the top plate, i simply drill out the holes for the standoffs.
That allows to guide them through the plate, so i can screw them down to the bottom plate.

I guess this feed-through gives a little more strength in the frame as well. For the camera i made a hole with a dremel, so it can sit on the bottom plate too.

I like your enthusiasm for my build, Alex and lolFPV, thank you! I probably put green props on

Thanks, sounds like a great idea. This build has made me want to get a ZMR250 now.

Just to give you a quick update on my build:

I'm trying to fit a Mini 3D gimbal on my ZMR250 just like Oscar did, but without the mounting board. 
But I really have concerns about hard mounting the gimbal to the frame, perhaps just a noob would do that, but I haven't found a good way to mount it on dampers yet. Ideas are welcome
The COG is slightly off to the front, but it should be ok (btw any tips on finding the COG?)

Other than that:
Is it a good idea to use DAL 6045BN with cobras 1960kv and littlebees 20A? AUW is 836g. I'm probably killing those littlebees..

It is pushing the little bee with that setup
any reason why you can't use the mounting board with dampers? it worked really well for me without the dampers you will have more micro vibrations in the footage... so it's recommended!

Nice build. It's missing mud and scratches though. I personally would get a 90 degree adapter for you vtx antenna and point it backwards.

I've lost her in a LOS flight, stupid me
Does someone know a small and light GPS tracker?

Sorry to hear that, I really liked this quad.

It's not GPS but I quite like this https://www.thetileapp.com/en-gb/

Sorry to hear, looking at your setup ? Could you have used the taranis to locate the craft ?

feel your pain! I lost my quad, a gopro and gimbal over a steep hill last month.
