I have three large airplanes now (and want more) and my wife is complaining about me taking up two small bedrooms with them. Any ideas on the best and CHEAPEST way to hang them in the garage? I've seen airplane hangers for sale for 30 bucks or more online but I don't want to spend that much for each plane. Any ideas? I live in Las Vegas and the garage gets to be about 130 degrees or more at times, is this safe for my planes?

Thanks for ideas.
