RE: How big of a generator do I need ?
4 battery packs does me fine - can make the 4 flights on a saturday (charge a pack or two off the truck if I want practice or late flying) and recharge in the hotel room. I have a 5th set - really only use all 5 sets for a full day of practice. Used to fly 10-12 flights when I started the hobby a few years ago, but now 4-5 good practice flights is about all I'm good for. Now have a foamy and another small plane for flying around later or between practice flights.
