I don't log the number of flights, but the three FP packs have been in the models for about 40 hours of "transmitter on" time.
I'd guess that equates to something like 30 hours flying, at around eight minutes per flight say seven flights per hour.
So the three packs have done 210 flights this year;seventy each.
As I said before, observed flight performance hasn't changed yet-and mAH used/put back seems to stay pretty constant, more or less, according to how windy it is mainly.
