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.
