Car choice is all u I have no exoerince in any but the serpent truck and all the others listed are very nice and durable. As far as servos I'm futaba all the way! Also ko propo radios are sick, and for great cheap price engines the nova p5 xlt rips a truck around like no buddies business. Also werks is pretty nice along with alpha and I like the euro spec drnamite .21. It's underestimated because the name but they are strong and last. Very smooth with snappy bottom end. Got 4 1/2 gallons on mine and still rippin and it's been through hell plus tunning the thing is cake!
