My first RC project was actually a helicopter. A steep learning curve but well worth it.
From there, planes, cars, and boats were easy. I usually build my own kits.
It's part of the fun. I have done a few from scratch since I have acquired a 3D printer. I have joined many clubs, met a great bunch of guys. I don't get to fly much anymore. I am 82 and acquired some back problems, but I still occasionally manage to get out.
