While the 180 mini quad is booming, FPVModel also released their ZMR180 mini quad frame.
ZMR250 has been one of the most popular mini quad frames – it’s cheap and solid that many of us used as a first frame for stepping into this hobby. And finally here is the scaled down version of ZMR, the ZMR180!
As a long time ZMR pilot I was very curious about this tiny copter frame. In the end I pulled the trigger and purchased it from FPVModel for £24, free postage.
This review is written by Artur Banach.
There are two version of ZMR180:
- for 1806 motors with M2 mounting holes
- for 2204/2206 motors with M3 mounting holes
Reviewed frame is for 2204/2206 motors
Frames package includes:
- bottom unibody plate
- top plate
- camera plate
- MATEK Mini Power Hub (PDB)
- aluminium red standoffs (ZMR trademark :) )
- nylon spaces for mini PDB
- instructions for PDB
- Power distribution board
Supplied Power Distribution Board has:
- Regulated 5V and 12V outputs (not sure if filtered for FPV gear though, most likely not)
- Camera and VTX voltage bridge
- ESC voltage input pads.
At closer look
The design has a lot of similarities to the bigger 250 version. Top plate looks pretty much like ZMR250 with similar cutouts but is only 130mm long. It has the same width as 250 which is 50mm in the middle. Same 35mm aluminium standoffs are used here, but there are only 6 of them instead of 8 in a bigger version.
Bottom plate is unique and there is only a few cutouts with biggest one under the FC location.
Top plate is 1.5mm thick and bottom unibody plate is 3mm thick. Diagonal distance between motors shafts is exactly 180mm. Bottom plate is very stiff, I couldn’t find any flex at all. Very well done. Total frame weight including standoffs is 75g – very light.
FPV Camera plate is tilted by design and it is good to see this feature here. In order to fly fast, 180 frame require a lot of pitch tilt.
Compared to a typical 250 mini quad sized frame, this 180 frame looks absolutely tiny. Despite the small size, it will allow for great acro performance and superb agility. I am looking forward to building this ZMR as a side winter project :)
Positive things about ZMR180:
- Quality of carbon fibre
- Simplicity of design
- Supplied Power Distribution Board
- Did I mention the price ? :)
Negative things about ZMR180:
- No supplied HD flight camera plate (like the one form the bigger 250 version)
- SMA antenna hole in the top plate may require adjusting in order to fit the plug
- Supplied PDB most likely hasn’t got built in LC filter.
I was really impressed by this frame. Simplicity is its beauty here and the fact that it comes with a PDB makes is so easy to build, even as a first FPV frame.
