F5B propulsion 6s vs 10s
I'm currently equipping an Avionik for some F5B FAI competition.
It seems that there are globally two families there : those who are running on 6S and those on 10S
I'm still wandering which one, I'll choose, do you have suggestions, ideas, advices ?
Thanks in advance

I am just getting into f5b, my rw2b has just started arriving and I have a b-08 on its way. Both are 6s setups. However the consensus is that 10s is the way to go.
The biggest benefit is that the controller and motor are both working within their designed specs when running on 10s, the stresses are all win the expected norms. Whereas on 6s everything is getting hammered much harder.
That's what I have managed to glean from the mountain of information so far.

That went fast. B08 on the way?!
When you say Avionik, which one?
You will struggle to fit in a 6S or lower cell count setup with big enough cells in the B12 onwards, it is made for 2 smaller packs (2200mah max) sitting behind each other. The B08 on the other hand was made to accept brick packs like 6S 3300mah. These practical problems will decide for you.
System efficiency wise, there is still no proof that 10S is better then 6S. You will see Patrick Hausler mixing it up with the top at the WC flying 6S. From my measurements even before 10S was legal, the 6S motor of the same size with the same power was running cooler. However it is true that the ESC has to work harder with the higher current of the 6S setups and there are not many ESC's out there that can take these currents (300-350A).
Inside our outside of manufacturers specs, it is no guaranty things won't burn!!!
Personally i am running 9S 1800mah as are a fair few other people. With the same motor you can run 10S and smaller props or save some weight and fly 9S with a bigger prop.

Higher cell count is the way to go. Over all system load is reduced and a competitive setup with Neu 1512 (or the corresponding Leomotion) and Castle 120 HV is very affordable. Especially the Castle ESC should be bought second hand to reduce the costs even furhter.
