Im just getting back into racing after about a year off.Where I live there are no onroad tracks,so Im switching to offroad.Im going to be running an Adam Drake 2.The question I have is this,I went to my LHS to buy a radio.I found a CRX on clearence for 135.00,the kid that worked there said I didnt want it.I asked him why and he said they were'nt that good and there were some programming issues.Ive never used a Hitec radio I dont know anything about them.What kind of issues are there?
