in need of advice...

i can't believe how much information is on this site, it's crazy.

i have a couple more questions:

for the bec is there an advantage of the ubec vs. the ccbec if i'm running 4s? i see that the ubec has a max input of 40v, but for a 4s it seems, to me, to be just a preference.

battery holder? i thought of just using gorillamaxx velco straps w/ some kind of padding, but see a bunch of guys build actual housings.

is the stock spur gear ok?

lincpimp you wouldn't happen to have a picture of the capacitor installed? i'm much more of a visual type person.

thanks again
