What moments???????!!!!!!!

Dave Hull:
Exactly, Bob. I don't think you're going to need anything like this kind of accuracy, but if you knew the exact proportion of your fuel components thus permitting you to calculate the number of moles involved and recall Avogadro's number (6.022142x10^23), and since you are metering by volume you know the exact composite temperature of your mixture, then you could figure out how many electrons Denny just pushed into his fuel tank by doing the math. Or, you could take the easy way out, not bother knowing how many electrons were involved in flying and just run some kind of battery. When the charger says it's "full," you go. Just sayin'.....

I always weigh my planes with a discharged battery just to be fair.

Dave Hull:
Well, I think we can make the generic statement that those who are using non-combusting technologies in their stunt machines are not expending any electrons at the system level at all. A control volume analysis would easily validate this conclusion. They are all still there inside your "zero emission" but highly polluting interchangeable housed chemical repository with the wires coming out of it. During operation you are merely perverting them from one chemical form to another. And then you apply a brutal grid-based technology that increasingly is based on the total decimation of the balsa-containing element of tropical forests to force that more stable chemical composition to change its attitude via "reverse" redox, thereby screwing up the entropy of the universe. All this happening inside the beautiful disguise of (hopefully) a classic-looking stunt ship such as a Dolphin.

With that understanding, as a frequent pit boss/pull tester for SoCal events, I can say that whether your housed chemical repository is fully in one state, or the opposite state, or is in perhaps in an 80/20 state does not concern me at all.... But if I felt you were actually losing electrons I might emphasize the use of a dispersive cylinder technology featuring a carbon-double oxygen compound.

Steve Maines:
Power will be an OS FP35 with the OS muffler, which is the engine that the plane came with. I/m not sure of the size of the fuel tank as it's internal, but I will figure that out shortly. I have a few repairs to make to the covering on the wings, but the rest is solid and I don't see any issues. Winter has set in so I won't be flying this until next spring. Looking forward to flying this one.
