Thanks Adam I'm in a unique situation as I'm retired and spend many hours at the field with friends everyday, I hardly ever fly more that once an hour but I may spend 6 to 8 hours at the field so I can get 8 flights in a day without being rushed, the only problem I see is contest, in this district they do fly one line then the next line sometimes making back to back flights, and as I said this, I'm sure, would a temporary thing build batteries and chargers as time goes on, and could actually do another thing I wouldn't have as much invested in old technology, so I could be in a situation of getting newer batteries and chargers as they come out, $600 can buy a lot of gas for a vehicle running at idle.
Thank you very much for your input to the forum and this thread, lots to think about for next year.
