For me, I have both foam and balsa airplanes. I have no problem with either. I don't find the balsa ARF process any more difficult than a foam airplane assembly, other than the time required to assemble it. If someone would build one from a balsa kit for me, I'd have no issue flying it at all. I'd even be glad to pay for their services. I just don't like putting them together, that's all. Lazy? Possibly. But what's weird about me is that I absolutely love the assembly process of helicopters and quadcopters. But I don't like assembling airplanes. Just the way I'm wired, I guess.
