minerran These are not designed to be used in parallel. Not sure what you're trying to do but if you wanted 7.4V@6A to drive motors, please double check the maximum voltage rating of your motors, most can handle 3S so you might not need a 7.4V. You could use this module to supply 5V power to your flight controller which should not draw more than 1.8A. Since Lizard95 is just a frame for a scratch build where you choose your own components, suggest you just choose parts for a 3s system and forget about 2s.

minerran Don't understand what you're trying to do. All flight controllers (even those with built in ESCs) are only 36x36mm and a TO-220 package part like these won't fit. Flight controllers have surface mount parts and therefore are not really repairable? ESCs themselves come as modules and again, are not really repairable. You can't open one up, remove a bad transistor and put one of these in its place.

minerran Look at the reviews and you'll see pictures. The triode is mounted to the heat sink with a screw, When screwed in, the whole body of the triode is contained within the heatsink, if not then you put it backwards. When installed into the board, you can see the triode and the heatsink does not extend past the PCB edge and does not stick up past the top of the transformer. A tip... screw it onto the heatsink BEFORE soldering onto the PCB so that the everything will align correctly.

minerran The schematic is here as a picture in the product description. It generates ozone because I can smell it when I see the spark jumping between the two wires of the transformer secondary.

minerran Its high voltage AC but is a pulse, not continuous.
