Dunno if I count as an old-timer yet, but I've been busy throwing my money at my RC collection for the past 3 years. I seemed to hit a critical-mass of knowledge, expertise, and spare parts in 2015, because my collection absolutely exploded last year. I have 27 vehicles now, one of which is an airplane with a 5-foot wingspan. It uses a discontinued rotary engine, the only one ever made for RC use, which I have three spares for. In the past month I've been selling spare parts that I'd been accumulating since last summer, all of which were sold at a loss, and still recouped over a thousand dollars. All of that has been spent on new parts, some upgrades and some spares. I've had to make a no-new-vehicles rule, but that's not too hard to enforce because 1) I bought all the vehicles I wanted just before implementing that rule, and 2) I'm out of shelf space. I'm going to be paying-off all that stuff for a long time. It sounds financially unwise, but after a series of severe panic attacks in 2013-2015, I realized that if I die tomorrow I'd rather die having had the opportunity to own the toys I've wanted since I was a kid instead of dying debt-free.
