How many flights do you typically fly during a day at the field?
I was wondering what you are limited by. For me, I am a social person so I like talking and looking at others "toys". So I typically fly only 3-5 times on a typical day. If there is someone on my channel it is usually less as I don't want to monopolize the frequency.
Now that I am switching to electric I am wondering if it would be better to just buy 5-6 battery packs and save the cost of a high C charger and associated power options (deep cycle batteries, generator, etc.), and just charge at home with a 1C AC/DC charger.
I normally bring two batteries for my plane when I go out. I change one while I am flying the other and just change it at 1C. This is enough to keep me flying for the day and I fly just as much as when I was flying glow. Normally that about 6 or 7 flights a day if I stay out all day. I normally don't take a battery with me as the club has charging setups at the field. If I take my Super Sportster, I can get 3 normal flights on one change, since the battery is way bigger then the plane needs to fly. It just needs that big battery ti get the CG right. I also take a couple of planes so I am not flying the same one all the time, and I always have one ready to go when I am.
My models are mostly 1KW and larger in size. So, having four or five LiPos on hand for a half dozen models gets to be quite a few $$$$.
So, they've all got A123 cells that can be charged at just about any rate your charger can put out. Problem is, with a 12S2P battery pack, it takes a pair of 120 Ampere Hour deep cycle lead acid batteries, and then those batteries will only last a bit more than a year.
So, went to a gasoline engine/alternator power supply!
always take 3 planes,with 3sets of batteries[series,and parrallel] for two of the planes and 3 or 4 bateries for the smaller plane..average # of flights on a good day...6 maybe 7. sometimes only a few if it's real crowded and the conversations are good.
narrow is the place to land...wide is the space to crash....choose the narrow way!
I'm usually limited by time, there are always other things that need doing at home. But I try to cram as much air time in as i can during the time i have at the field, i usually get 7 or so flights. With 2.4HHz frequency restrictions isn't an issue any more so the only limit is how fast i can swap over batteries!
