I liked building the 1/8 scale nitro buggies as a young man, I still have a 4wd 1/8 siting around somewhere. Can't really get parts for my old models anymore. I now put the money into motorcycles and a fishing kayak. Its hard to find a place to run serious RC cars here, no tracks. I guess its mostly a teenage thing. I bought my last RC kit when I was around 23 years old, I just got a cheaper thunder tiger 4wd buggy kit, its mostly the build that fun for me. I put a new more powerful motor in it a few years ago and new wheels, new servos, new front differential and ran it a couple times. I got offered $400 for it 5 years ago, should have sold it in hindsight. The nice kits are like boats, you just pour money into them. I like my motorcycles better. I can ride them often or occasionally, go on long trips and camp out. I get more enjoyment out of other things, RC cars were fun before I had fun cars and bikes.
