My 2400 geared 22/50 maintains low temps at all times on grass or pavement on 2s, have yet to try 3s, top speed is 42mph. However, my VXL-3S will get hot enough to go thermal after 15 minutes or so in tall grass but that is WOT the whole time unless I'm turning around. Can't say that it is a dog even on 2s so I'm sure 3s will be nice. Geared like it is I can do backflips on pretty small jumps. I'm pretty tough on it all the time and when it goes I will be going with the 2650/MMX combo but I don't regret starting out with the 2400.
