[NSRCA-discussion] 12S for F3A

[Stuart Chale]

Unlike removing the weight limit (which I think would obsolete current equipment) it is not as clear to me that going to 12S would.  We still have the 5Kg weight to limit plane growth.  So if it would make it easier not to burn up battery packs, and or produce more power if wanted or longer flight times then it seems like a good change.

I do have a 12S heli and although 10S makes a nice snap when connected, 12S is a real manly snap/spark when connected :)

I think adding 12S makes sense - it would have zero impact on anyone flying an AMA class so there's nothing to buy.  Those in FAI would have the opportunity to fly F without trashing batteries all the time.  I'm all for it and suggest that if others agree we let our opinions be known as Mark suggests.  The F3C precedent is worth noting, but there are very real and practical (unique to us) reasons to pursue this in F3A.

Well….  At face value, much like the F3C community (already running 12S), the higher voltage allows you to produce the same wattage with a lower amp draw.  More efficient on the batteries, and everything runs much cooler which is better on the motors, batteries and ESC’s.

The concern of course is that it potentially allows for more power if you chose to still pull the high current.  The proponent argument is that power is currently unbound (on the glow side) and we’re not seeing any changes to designs and this would allow much more efficient systems.


If there is a strong feeling about this, comments from the community really can drive the issue (in either direction).

What does that do for us?

Please propose 12s power setup.
