I am new to FPV and currently I have a Radiomaster Pocket and am practicing my skills in Liftoff and Liftoff micro drones. When I get good enough my plan is to make a budget 5 inch freestyle analog drone, and I know that the IFlight Nazgul Eco is cheaper but I really want to make my own drone. I have already picked out most of the parts out of which some are from AliExpress. Is it worth the risk to buy from AliExpress? I see they have some good deals on things like frames, VTXs, ELRS receivers etc.
