Ofcourse I will choose V-one R4... I switch from Xray to Kyosho and my lap times improve a lot...(1.5 sec by lap!!!)...I won 2 stages from national championships, and make the TQ an de Best lap of all the tracks of the nats!!!...
But...If you are noob... choose a Shimo used...if you are more experienced...R4 rules!!!...
