the first thing I would ask you is why do you need that much speed?? I have both vehicles and there quite different. he hellfire is designed for racing as a entry level machine, The Jato as??? basher that wants to just go fast! It loses traction in the dirt, and tends to spin out with the slightest throttle .. let me ask you something! where in the dirt can you expect to go 65 mph? I suspect you just want to go fast, if this is there case then buy the Jato, it will give you the quickest return for your money!! If you want to keep the Hellfire then seek out race tracks in your local area and practice beating the track!!
