So, it is an electrolytic capacitor and is soldered to the positive and negative where the power ( battery) wires attach to the pdb/4-in-1 esc.....................correct? Also what would be an acceptable voltage and value? I really appreciate the instruction which I will pass on to others.
i just had alot of experience with caps. on my last build...seems my escs couldnt handle any braking voltage spikes..and my FC was adding to it...but i put mine on the BATTERY terminals...there is a line maybe with an arrow..that is negative, the other is positive, that is the longest wire..yes, seems weird, but they go on NEG and POS... you should put it closest to your problem..they say!!..i say BAT.TERMS.
i used 470uF, on my 3s build RS2306 2400kv emax motors, emax bullet 30a esc, 75c 3s 1550mah batery,(AND exactly same set up BUT emax 2205 2600kv red bottoms)
and..i used 100uF on 1306 4000kv emax red bottom mini and 3s 850mah battery 30amp bullet escs..
everything is fine now...i didnt have a problem with frying things,,it send back voltage spikes to my FC and sent my TX into failsafe...bad bad things happen then.. your LC filter should have CAPS. on it..the yellow things are capacitors...i have a LC with a 470uF on one of my quads..but the 12v regulator before the
LC filter blocks the spike and sends it to least path of resistance, via full voltage power wire to my FC...good thing i was only running 3s...4s prolly would have fryed my FC..
BUT...my point being is that if you are running 2s you will NEVER need a 12volt regulator and a LC filter that should be before your VTX anyways, should be fine...but im not paying for anything if it frys...im just sayin...2s dosent seem that it would have effect...might help VID. quality though.....hope that helps....lol...
