Hi, I am interested to get a SD. I have a XRAY T1R now and I am very happy with its performance. On club track, I've seen many people playing SD and they always need to adjust the car's setting and tweak the car after every few packs of batteries. Does SD need lots of time to do maintainence? To me, my T1R is so simple and I can describe it as a "build and go" type. Any comment for me?
