Thanks again and especially for what I got as the numbers from John Agnew !

This is a very convincing answer ! Although I wander if those batteries will reach
100 cycles, anyway the very solid saving from "fuel" is there present well.

Frankly, I thought is the other way arround, but John's calculations are solid !

If and when I am going Electric is another question having in mind that I like the sound and
the smell of the GP fuel for more than 15 years altogether RC flying. And on top of the whole
mix of pros and cons I need to confess, I am pretty well decorated as a radioelectronics
engineer... Well, all we are emotional when it comes to RC hobby and thus the Numbers
like those from John are clear answer to all emotions. It seems that if F3A has gone so
deeply furnished by EP solutions, then the EP dominance in the less demanding classes
is pretty soon taking place. Well, I still have a bunch of very good GP enignes with
althogehter resourse of maybe couple hundreds of hours; maybe I should consider
getting some of them into eBay...

Surely the discussions in RCU are great and I am very thankfull for all constructive
answers !!!
