There ok, Shalf driven good entery level car.. Should be easy to get parts for them at your hobbie shop if not online..
Make sure you run it in for like two 1 liter bottles of nitro.
Make sure when you start it you dont stuff the pull start, small fast pulls, cos they have a compression point where it will fire. kinda like kicking you bike from tdc..
There lot of fun i drifted one of them but batter power.
