[NSRCA-discussion] 12S for F3A

Fri Nov 11 05:05:02 AKST 2016

Anthony, You’re correct in both the flawed logic (outcome anyway) and progression of the engines.   But this does have some differences. Shifting to 12S only changes the windings on the motor.  Same motor, same tooling, same mounting, basically the SAME motor, just wired for lower Kv.

But I hear you…

That was the same logic behind dropping the displacement rule. To open to alternatives and so the YS didn't have to be stressed so much. The $450 1.20 AC has grown to the $800 1.85.

How does developing a better power system that is less harmful to equipment and easier on batts not better.

This opens another option.

Has anyone researched the actual cost of 12s system other than the few of us who have considered and tested and suggested it?

Just keep make it harder for people to get into pattern! Human nature is if xyx pilot is flying a 12s plane then we must fly it also to be competitive.  Why not focus on recruiting people and not push them away.. WHY does everything have to follow the FAI planes, patterns etc?
Leave the AMA classes alone get the pattern SIG to fix the problem and not keep adding to it.

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.
