Hi there,
Half a year ago I started the miniquad hobby and was surprised how cheap these things became. But as a hobbyist I wouldn't even think about buying a RTF quad, if I can built one myself. So here we go.
Update 1:
I completely removed the top plate + spacer which saved 5g weight. Also got this Lipo https://goo.gl/uzUhyF which saved another 23g weight. And i got these props https://goo.gl/s1RhKe
That thing moves like a rocket now.
Update 2:
Because new flight controllers and escs got developed, the price of this quad is now down to 60€ (esc 4 in 1 14,50€ https://goo.gl/RgndNd) but some parts like this new esc may not fit my frame anymore, therefore I've added the 123 design files, so you can edit them on your own

The parts - cheapest build possible
Motors:
Racerstar 1103 8000kv (4x 3.47€)https://goo.gl/59hkXr
Flight Controller:
F3 16mm (11.25€) https://goo.gl/MDHzSa
ESC:
Racerstar 6A 1-2s 4in1 (23.48€) https://goo.gl/SZm6fa
Receiver:
Flysky irangex (NO FAILSAFE) (3.11€) https://goo.gl/JJ2AAr
FPV camera:
600TVL CMOS (5.70€) https://goo.gl/jjYmBt
FPV transmitter
Eachine VTX02 (7.82€) https://goo.gl/T8LBZM
Propellers:
Eashine 2035 5 pairs (3.49€) https://goo.gl/o8BdQ9
That's together 68.73€. As always with these chinese sellers, the prices change permanently. So if something is much more expensive than listed here, maybe wait for the next flash sale.

If you have a few bucks to spare I can really recommend these upgrades
Better flight controller with OSD:https://goo.gl/Hy4Lo2
better receiver with failsafe:https://goo.gl/LywVcC
FPV camera with higher resolution:https://goo.gl/PRjPgW
Frame out of carbon:https://goo.gl/Rkb5G8
The weight without battery is 51g.
Im still tuning this quad and looking for a decent battery that is light enough but still delivers enough power. Don't buy ZOP Power lipos. I had a brown out after only 2 minutes of flight. Waste of money.
