[NSRCA-discussion] 12S for F3A

Mon Nov 14 13:45:55 AKST 2016

Top 10 ways to die associated with a Pattern Plane:

1)    Wife tricks you into drinking 2 cups of Glow Fuel

2)    Short out a 2S LiPo receiver battery and burn down your house

3)    Fall on a prop and skewer your liver

4)    Stick your head into a spinning prop and sever your Aorta

5)    Try to catch your Pattern Plane while landing (severe head trauma)

6)    Get hit by a semi-truck while driving to the flying field

7)    Glue your fingers inside a fuselage and die of starvation before someone finds you

8)    Get decapitated by the 3D helicopter in front of you at field

9)    Get hit by meteor while retrieving plane after landing

10)                    Blood Sepsis caused by bedbug bites at cheezy motel in Muncie

Hmmmmm . . . . didn’t see electrocuting myself with 10S LiPo anywhere on the list.  

Not even sure how you’d do that . .

But it takes volts to overcome skin resistance.

Hi Tom,

You may be right but keep in mind, it's not the voltage that kills you, it's the amps.

Hi All,

Interesting discussion about the batteries. I thought the rule was 42 V DC.  Are there not serious health implications, i.e.  just how much the body can take? I was always under the impression the rule was safety based and is why the FAI imposed the 42 V rule all those years ago?

I am purely going off what is bouncing around in my head…but I doubt, the FAI will change a rule if its safety based?

I’m pretty  sure all we’d get is a rapid movement back to Glow which has no bound for displacement and therefore power.  At least in FAI and Masters.

Let's cut cost and increase participation by reducing to 8S rather than 12S. Airplanes will be smaller and cheaper, batteries will be cheaper, and we won't have to worry about the weight limit. We won't have to worry about the 2M  biplanes that will be bigger (the logic of that argument about the weight limit gives me a migraine trying to understand how 2 meters becomes bigger).

+1

Adding the option of 12S is about efficiency, being nice to your batteries....

To Andrew’s point, power is already unlimited in our rules.  Glow is not constrained, only E-power.  So while normally I’m a staunch opponent to any rule change that will alter the designs of our planes and thus obsolete everything and increase costs, I don’t think supporting 12S does that. 

Power is not currently limited, so allowing 12s doesn’t change the available power.  It merely allows those flying electric to do so more efficiently.  And yes… A YS200 will likely  support even larger Bipes if they can build them and make weight.

Then cap the wattage we can reach, But don't worry when YS comes out with there 200 that won't allow the pattern planes to grow as long as there under 5000 without fuel right? 🤔
