I do not have experience with Futaba, but I have a couple of JR systems.
I fly sailplanes, or electrics and use 700 mAh batteries in the models on
the sailplanes. Electric timnes are constrained by the motor batteries.
I figure at least 1 hr or more on the transmitter. This seems to be the
determnining item in the equation for me. When it gets down in voltage
too far, it wilkl shut down, and that ends the session. I haven't had
mine shutdwon on me while flying, but I don't do much after the trans hits
9.5 volts. My battereis are old and are probably due for replacement.
Our sailplane contests are usually set to that all flights will total way
less than an hour for on model, usually around 30 to 40 minutes.
