Thanks Guys !

Among the very interesting answers I would mention the most impressive one is what is written
in the signaure of Silent-AV8R: "Reality is Subjective." And it seems so far we did not get anyone
here telling that he has flown so Many Hours at the Cost of xyz-dollars more than the cost of the
other approach. Of course I hope that someone was doing this simple Math:
GPcost= EquipmentCost/HoursFlights and similarily EPcost= EquipmentCost/HoursFlight
And in fact this measure (GPcost vs. EPcost) would be subjective and exposed to market development.

Surely sort of summary at this point comes from OhD: "Pattern planes are right at a point
there it is not a clear choice but electric is gaining fast. "

Frankly, I believe that Electric F3A will gain gradually over the GP when the Electric Cars get
on the roads some visible presence. Just to mention here Silent-AV8R's comment which also
came from Tianci: "With electric you are buying all your fuel up front all at once."

But the PROBLEM is that one cannot be sure How-Much "fuel" he purchased because
it seems there isn't any handy Method so far to know how long Battery life is going to
be especially under the Huge Currents needed for performance of F3A, isn't it ?

Or, is there some method & instrumentation to predict the Battery Capacity
Wearing-off, i.e. so called "State-of-Health" at the first couple charge-discharge
cycles ?
