ZMReborn or ZMR250@230 3PV rig
So, this is my 4th modification of still living ZMR250 frame (as I still have many spare carbon parts) where Im using 3D printed spacers between the top and botom plate.
this was build before (which I crashed) made with nylon spacers.
https://rotorbuilds.com/build/18333

Advantage is lower weight than original frame, even with 3D prints. Frame is shorter and thinner, motor to motor is shorten from 250mm to 234 mm and most of the parts sits inside 3d prints.
Im using this for 3PV video and so camera is beside the frame and you can se drone in the video. Camera is Insta 360 go.

3D DESIGN:
As ussual I started in Sketchup (and before that caliper and lot of measuring) and if someone needs, I can share all the parts on my https://3dwarehouse.sketchup.com/by/wizzx

Than I print many 3D prints and tests

As I cut original carbon just manually (with saw and metal file) I lasercut some sticker and stick it to original plate and than manualy cut.

Motors are closer than original ZMR, arms need to be modified as well

BUILD:
I'm using integrated VTX and PDB (Matek FCHUB-VTX) - need to save some space - bottom plate needs to be grinded to fits VTX:

I'm big fun of fixed XT60 on the frame (means really fixed) and I never had a problem with that. Also I'm use hard copper for XT60.

Glued buzzer and LED into that rear 3D parts

MATEK F722 STD and Crossfire NANO, good old Red Bottoms and crossfire antena just glued in the front - next time holders can be part of 3d prints (during 3D desing I was on radiolink recievers)

Desing of insta360 go holder was also tricky.
First design was not so good because it was hard to insert insta camera into that.
Second was reely good and light...
But I lost my insta in the forest during flipy flopy.... grrrrr (6hours of searching, GPS tracking of searched area, involved more people to search - nothig helps) but insta360 send me a new camera for a 90euro.. not bad.
Alt Tag

so I stay with a 3rd (actualy around 13th) design of insta360 fixture.
It goes really hard inside (specialy if theres cold weather), but better then lost camera.
BTW it is printed on flexible SLA resinhttps://s.click.aliexpress.com/e/_A9Q211

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
