That Caster looks to be very solid , I have seen it run in person and it was very stable looking on the track . Very hard too beat its price point also .
This is all my opinion on what I have seen , I own an RC8e (converting too a SC10 4x4) an Ofna Ravager , and my son has an RC Monster converted Xray 808 , the 808 is a sick buggy also but its pretty expensive .
