After 2.5 years of racing I got burned out recently. Took a 6 month break and just came back last month. I think the break really helped. Somehow during the break it helped me realize that I didnt need to buy all the latest / greatest stuff to be competitive and have fun. When I came back I surprisingly had not dropped off much skill-wise and after just a month of racing I feel like I might be the best IVe been (though I still have a long way to go, as do most of us).
I had grown a little tired of the nimh vs lipo and brushed vs brushless debates. That is mostly solved now so people seem a little less stressed. Rubber tire racing has picked up in the area which just further increases the fun. While I have made some upgrads to my car it hasnt been the cash drain it had been before.
