5S or 4S

[tom255]

Need to find Gold SPOT.
I know in my track 40+mph its realy usless
What u all think if i gear it same high as 4S but use 5S battery with reduced trottle travel, lets tell ~ to 80%, i mean in that case if i want to use 4S and 5S without messing with gears. If i will buy 4S and spare pack 5S
Can i get more runtime from 5S againtst 4S without thermal issue?
Realy i dont want to use any vents or something, its looks so ugly and 1 more moving element and weak point.
Why i am asking becouse i dont have any experince with brushless conversion and its my first build. Theory is one but practice can be other.
I am educated in electricity so i know what is this, its not new to me.
And i want to be sure with battery choise, because if i order Lipos from here and they are not cheap, import taxes and VAT add more 25% to battery.

cemetery gates u have similar setup what i want to build what is ur ESC and what runtime u get from yours 5S 4000 lipos? any temperatures will be helpful to understand which temperatures i can expect.

Here I am first guy who wants to build BL Tryggy my mates laught on me. I want kick some nitro asses. And my goal is not to do pit stops and win a time in outlaw calss so why i want to use high Ah battery.
