    1. Quality

      Great size Pdb matched it with 4 in 1 esc for tidy build. Great price and quality.

    2. Haven't fried anything since switching

      Posted by jRedFive on Mar 18th 2016

      I used to use a hobby king basic pdb and kept frying my vtxs from voltage spikes. Switched to the ubad mini pdb and haven't fried a vtx since. Its design is pretty well thought out, convenient placement of the vbatt and ground pads is a plus. The 12v filtered pad gives exactly 12v, even when throttling up. and the 5v reads exactly 5v as well. I like that i can see the ubad logo through the hole in the 250s belly.

      The shipping was super fast, I ordered it Monday morning and got it Wednesday morning, I know I am only 2 states away but that was a huge surprise. Overall I am so happy with this purchase, and have bought a second for my 210 build.

      One thing I cant touch on is the osd capabilities, I read that it has some osd stuff and I can obviously see it printed on the board but, I watched the video on this page and since I don't have an osd I soldered the pad basis UBADs recommendation and it works perfectly for me.
