RTR is absolutely the worst thing I could imagine for the hobby. New RC enthusiasts have no clue how to wrench on their stuff because it came built. I want an LST but I also want a Futaba PCM radio and a .28 sized engine....Also want to build it from parts. Long gone are the days Im afraid. I will always remember building my first car, Kyosho Turbo Optima Mid SE....Complex car and tons of fun.
