One of the things I'm trying to do this year is make time for my hobby. My buddy and I have built a couple of electric "sorta-scale" warbirds and have been flying them a great deal. They're fairly quick to build, can take a massive amount of abuse for just being foam. The all up cost is not too expensive, however the one thing we've found with electrics is you can never have enough batteries, as they typically take about 2 hours to charge.
It's kind of a tradition that I take a picture of my daughter with my new planes, however, as she becomes older she gets less happy with this tradition. The all up weight on this one is only 13 ounces, so it can only be successfully flown on relatively calm days.
