I have owned Traxxas products since 2002 and can testify to the reliability of their units. They run on 20% nitro fuel. I have done the break-in by the book and you can litterally run the fuel tank low, drive it to you pop the cap, refuel and take right back off again. Both of these vehicles run exactly the same as far as run time. The HPI RS1 runs 60 MPH and is equipped with an electric push button roto start and the vehicle listed below is the Traxxas Revo 1st Generation. It runs 45 MPH. It is all wheel drive with the 3.3 race engine. You can look on youtube to get an idea of how well this vehicle performs. I am willing to sell the RS1 for $200.00 and the revo for 300.00. You can buy both for a package deal of $400.00. For questions or concerns, you may contact Jeremy at .Thanks for you time and attention. (both run on NITRO 20% Race fuel).
