3d printed zmr 250 banggood budget build

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!

UPDATE 08/8/2016
pdb, osd and flight controller were all waiting for me when i got home from work, so i added a few piccies 😀
UPDATE 14/8/2016
Soldered sockets for the micro minimOSD onto the pdb then soldered pins onto the mmosd from there.
UPDATE 16/8/2016
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.
UPDATE 19/8/2016
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 😀
UPDATE 20/8/2016
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…
UPDATE 25/8/2016
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.
UPDATE 27/8/2016
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 🙂
UPDATE 30/8/2016
JST/dupont crimps and   3 x floureon 25c 2200mah batteries have arrived.
