I got an HPI Nitro RS4-3 RTR about 3 weeks ago and I am absolutly loving it. For a RTR its actually quite speedy. Its got quite sturdy construction and is shaft driven rather than belt driven. Its good for Nitro RC car 1st timers and has a large assortment of hop-ups. I got it for $300 at a local HobbyTown store. I've painted up the Viper GTSR body and have already started on a show quality ProLine Lexus LS-430 body. Heh...I even have a Lexus GS-400 body on order! Anyways, if your looking for a Nitro RTR kit, then you may want to look into the HPI Nitro RS4-2 RTR.
