im just trying to figure out how much more time you get with 2 4s verses 2 2s packs and is it worth my money because 4s packs r not cheap

Not to sound a hard ass, but the answer is the same as in twice the runtime....
If your looking for minutes or seconds of runtime, only you will be able to determin this by the prop you runt and how wet your setup is and how big your packs are in Mah!
4s 5000mah packs times two is 10,000mah = twice or two times the runtime

ok so i guess since mtwin said he gets 8 mins it would be a fair call at 16 mins but is that to long for the stock esc and motor?
thats what im trying to figure out if the 4s is worth the extra money and would i be able 2 use it to its full power

That's really up to you to decide, no one can decide that for you
most of us run for 4 to 5 min as in that's about as long as races are ran
you can set up the boat wrong and burn things up in less than one minute...
setup right and they will run all day long with no heat issues

I would buy 4s 5000mah 20c or 30c packs as those are fairly cheap and run them parallel
lots of runtime and plenty of amps for the last time

i guess what im trying to figure out is do i buy 4s or 2s i would hate to buy 2 s and then a few weeks later i want 4s, plus i want to be able 2 use them in my cars and trucks also since i already have a 2s and 3s pack i guess i kind of want the 4s for the boat and then i could use them for my trucks also, but i dont want to waste cash on 4s if its not really worth it and if the boat is going to get hot after a while
