[NSRCA-discussion] 12S for F3A

Fri Nov 11 20:14:36 AKST 2016

 Nothing compared to my 100S/1kA - 1.5kW setup!  Puts a grin on my face every time I hit the throttle!

Wait till y’all see my 75S-350Mah setup . . .

No!  We can’t use 12S battery packs.  We can’t be trusted around 12S battery packs!  We are being protected from ourselves.  Just do what you’re told and everything will be fine.

Why not just get rid of the battery size requirement, then you don’t have to worry about it.  (Same with weight)  

Once we’ve all invested in new 12S equipment (or quit pattern), then 14S will become all the rage.

Perhaps some of y’all missed it this week, but the wave of the future is less regulation, not more.

I am not sure that you can get much bigger as long as you keep the 11 pound weight limit.  Remove the weight limit and yes biplanes will get bigger.

Maybe I'm misunderstanding something here, but rather than going easy on a 12s setup, won't we just find a way to run the crap out of it (bigger props, for example) to power bigger, more expensive airplanes if that gives a competitive advantage?

I don't think the issue is about what's required. I read it as the exploitation of a 12s rule that will result in design changes and drive cost higher as the hunt continues to gain a competitive advantage .

I'm not understanding what significant design changes would be required to the airframe to take advantage of this change?

I don’t understand how this rule change won’t affect the AMA classes.  Most planes are designed to satisfy FAI not masters.  So all future planes designed would be around 12S rather than 10S making the plane selection for AMA even smaller.  This could also result in longer more complicated sequences.  Bad idea unless we are going to make the same change for AMA classes.

Yes, but we need fai to pass it first, then get ama to approve.

Looks like there would need to be a rule change to run 12s in an AMA class.  Current rule says "Electrically-powered model aircraft are limited to a maximum of 42.56 volts..."

I think a source of universal pride among the pattern community is the positive ripple effect that development of our gear over the years has provided the entire model aviation community.  This discussion is simply about the continued development of a power system...the evolution of electric power.  I don't think this would have any significant real or implied effect on any AMA class.  On the other hand, those that choose to try something new no doubt will - that's how it's always worked.  How many folks in AMA classes fly YS-185s?  That's a choice available to all of us right now.....  Our 10S setup is great and should/will continue to be the standard for a long, long time - yet not a reason to stifle development.

By changing the KV to spin the same prop at the same rpm as the 10 cell setup there isn't much that changes in the feel. I have hundreds of flights on the 12s setup, and the power output is no different as well as the torque. Heck if anyone wants to try the 12 cell setup and has there model setup for a Q80xs let me know. I'd be more than happy to let you see what you think.

I think it takes more than 12S to do that, Chuck . . .
