I fly with two young guys in their twenties who have been in the hobby for a few short years and have evolved into really good pilots and innovators. One gets the ARF versions of planes and drones and writes his own telemetry programs and FPV performance apps and its amazing what some of his planes can do. Another guy collects radio parts, motors, and other electronics through second hand sources and builds his own control boards and receivers and then 3D prints and builds his own planes. He's done a few really cool deducted fans this last year. Both finished college and have started families and careers, much like I did, and still kept up with the hobby. It may not be the traditional balsa and nitro, but its still building and flying RC models.
