There was a local flyer who flew "704" AMA RC Scale Combat way back when...with a 1/12th scale P-38. It had a pair of Conquest .15s. It was the most mangled looking plane because the owner was good at picking up all the pieces and gluing it back together. As mangled as it looked up close, it looked just fine after it was in the sky giving everyone else HELL who got too close to it.
I'm not sure..but I think Dane McGee over at the RC Combat forum has a build thread for a 1/12th scale foam B-25. He might also have it posted at the RCCA web site..?
