I put them in the trunk of my 1999 Ford Escort, the rear seat folds forward and it's amazing what I can fit in there. I can fit 2 1/5 or 1/6 scale planes, flight box, radio and extra props in it. Of coarse my nose is in the windshield, and if my wife and kid want to go with me, I just tie them to the hood of the car.
If I have to go to a show that's a few miles away I barrow my Father-in-laws 2004 Chevy Truck with cap and cab.
