If you mean fully assembled with no damage then at last count 31. If you mean plug in a battery and fly then probably about 22. I've been yanking gear from a few planes I'll likely never fly again. I don't know how I let it get so out of hand. The problem is I keep building and I just don't have room for any more until I sell off the pile of cars and trucks taking up a good portion of the hangar. I've got to get that stuff on craigslist for a local sale. Then I can build more planes. LOL!
