255 PC frame

My goal was to build as cheap quad as possible without compromising on essential components quality. So far it seems that hobbywing xrotors and sunnysky motors combo is the best bang for buck (I'm in EU so ordering better motors like cobras cost me more).
It's a custom designed frame cut from 5mm polycarbonate with 3D printed canopy/case. I wanted to maximise frame dirt-proofness up to the point where it could be made almost waterproof.
ESC-s are mounted on arms and vtx is sticked against fpv camera with metal casing so that provides some cooling even though vtx is sealed inside. There's also a foam made battery cover but I'll try to draw nicer solution soon. Also, there are going to be changes - I'll remove current lipo buzzer, rotate vtx 90 degrees so antenna goes away from battery, also may try to separate vtx from fpv camera but still keep them in one detachable block.
It's possible to use 2204 motors to reduce some weight but 2207-s are more fun, especially with 4S battery
AUW is aroung 560g with 1300mah nanotech battery.

Very unique build! How did you cut that bottom plate?

Good old dremel and hacksaw. Holes are by no means perfect but I did print out template/stencil and glued it on PC plate before cutting and drilling. CNC-ing would give much better results though.

Oh wow, that must have taken a lot of time! It looks very rigid though. How does it hold up to crashes?

What materials are you using to build the frame?

Well now your draft list can be legitimized. Looking forward to a photo!

Added some now. Btw, is there a way to add comments to photos or sort them?

I'm actually working on that. I'm reworking the discussion to make it work more like a build log.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
