So, some of you know that I have recently returned to flying/building after a 8+ year hiatus. My return has been with getting into EDF's for the first time and anything electric. As I have said before, I have always flown glow fuel prop planes. I recall flying for 8 minutes or more and landing because I was ready to land and not because I am being forced to land like it is now. So, my "observation" is this; am I the only one who cannot understand why we only get 3 minutes +/- on a 4S or 6S pack in a EDF? We live in a world where technology on most all fronts is beyond comprehension in some case yet the age old "battery" seems to still be 10-15 years behind. Don't get me wrong, I am thankful we do get at least 3 minutes or so nowadays because it used to be shorter times than that. I don't really want to go back to fuel mainly because of the mess. Plus, I love the way the EDF's look, fly and sound so that is not an option for me anymore.
I recently maiden-ed my 4S 70mm Rebel for the first time. I flew several times w/o incident but it "seemed" within a matter of seconds of takeoff my 3 minute timer was beeping at me. I had a fellow flier double check me and every time and the timer was accurate. It felt like no sooner than I was airborne and started getting into a rhythm, I hear my timer beeping. YES, all packs were fully charged and double checked by my meter and a fellow flier so it was not a pack charge issue. I did get the full 3 minutes out of every pack so I know they were at full capacity.
I guess I am just surprised at with all this world of technology, why can't someone design an electric system that will allow for at least 6-8 minutes of flying or more?
