Budget Bee 90 - A brushless micro quad under 70€

thingiverse

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. First flight: https://www.youtube.com/watch?v=2XRkdow9_do Flight with failsafe https://www.youtube.com/watch?v=AtjCswvAw5Y
