If you can find one, Pica used to kit the 182, wingspan was about 80 inches, I think. If you want a BIG warbird, most likely you'll have to go with somebody's plans and a kit cutter. Precision Cut Kits and All American Kit Cutters usually have kits already made from the most popular plans from guys like Ziroli, Palmer, Hostetter, Vaillancourt, et al. The L-19 is available in both 1/5 and 1/4 scale from Vailly Aviation (Roy Vaillancourt), and Jack Stafford Models also kits a 1/5 BirdDog.

I hope this won't be your first plane, though.
