    Looking for the best micro BEC

    Hey all. Got some parts but waiting for the play money to get my esc's, trying not to cheap out. Building a mini quad with some DYS BX1306-4000kv motors and a slew of different 3030 props to try out (2,3, and 4 blade props). Thinking of going for some DYS 20 amp esc's, but can't decide which model. I have a nifty little Eachine all in one cam (model EF-01), but have mounting concerns and it can only recieve 3 to 5.5 volts, so i need a super neato pdb with a bec or something seperate to power it along with my reciever and flight controller.

    Posting pics of parts in a few along with the frame and camera.

    There is the frame, pdb, and flight controller. Having to move the front posts to make room to mount my cam. Can't get the screws in the cam with the posts installed, stupid design,lol.

    That looks great so far. I'd strongly recommend ditching that PDB and getting one with integrated voltage regulators. I have a few different Matek boards and haven't had any problems with them. Otherwise, I'm a huge fan of Pololu buck converters. The power you get out of them is surprisingly clean and they're quite small. Here's a 5V 1A unit: https://www.pololu.com/product/2831

    For ESCs, the Racerstar 20A V2s are great and quite small. They're running BLHeli_S so they can run your motors are really low speeds (great for inverted stuff). Apparently they're rebranded Cicada units. http://www.banggood.com/4X-Racerstar...p-1074732.html

    That's another great option as long as you don't mind increasing your stack height. It also negates most of the need for the PDB, (apart from the voltage regulators). It's a real shame they're not included on the 4 in 1 ESC. Then it would be perfect.

    You might want to consider getting this one instead: http://www.banggood.com/Racerstar-RS...p-1080541.html It's the newer version with the 48MHz BB2 chip instead of the 24MHz BB1.

    My stack on this frame can be three high, don't mind, because it currently starts underneath the frame. I really want to bring it all inside the frame because it will sit so low and plan on crashing a good bit. Just want this one to be quality. My last three builds were all chinese junk at cheapest prices i could find. I learned not to cheap out, lol.
