My ZMR250 build
Finally got round to making myself a zmr 250 racing quad after flying off the shelf and diy micros.
Money is tight so i’m ordering a few parts a week, so far i’ve got the pdb,fc,osd,motors and esc’s paid for and on slow boats from china (all were separate orders).
I already have a pair of eachine ev800 that i use on my fpv micros but i thought it’d be nice to have a complete price for an all in rtf fpv zmr250.
I have 3D printed the top and bottom plates in glow in the dark blue pla, and the arms and other parts are glow in the dark red pla i will be printing other custom parts…xt60 & antenna holder for example.
While not everything is the cheapest component i still believe this makes for an excellent price to quality quad.
i plan to put a nightvision(ir) cam in, so i have been looking at 3w smd ir leds and would like to mount them on a bumper by just de-soldering the leds on a strip and replacing say 1 or 2 with the ir emitting ones…anyone had any experience with ir bulbs ?
All comments welcomed and appreciated!

pdb, osd and flight controller were all waiting for me when i got home from work, so i added a few piccies 😀
Soldered sockets for the micro minimOSD onto the pdb then soldered pins onto the mmosd from there.
ESC’s, motors, standoffs, M3 screws & lock nuts, and velcros arrived today 🙂
Realised the motors don’t fit in the cupped arms so i’m printing the same ones with a solid motor mount piece (updated in parts list).
Made a quick mockup of how itll look …see pics attached.
All other parts (fpv, batteries, servo motor for gimbal & other misc parts) have been ordered with priority shipping so should be here in 9 days or less and im off work until 5th of september so more pics & vids to follow soon 😀
Printed the tilt gimbal parts and added them to the frame, printed a mount for my cheap sports cam but it didn’t fit very well so im trying one that clips in…
Printed new tilt gimbal parts, this one protrudes from the front but fits my cam perfectly.
Printed a new mount for my sports cam that uses the clips rather than a bolt.
VTX, RX, Servo motor and my FS-i6s TX have arrived.
UPDATE 27/8/2016 – later on
De-cased the fs-ia10b RX and 3d printed a shell that stacks under the F3 EVO FC which i also just printed a case for 🙂
JST/dupont crimps and 3 x floureon 25c 2200mah batteries have arrived.
