This may sound like the least techincal reply, but I am recently re- newed into the sport. I bought a Revo 3.3 about 3 weeks ago and my friend has a T-Max.
Not just because I own it, but I like the Revo better than his T-Max. I used it on the track twice and it does well, (I'm still a nitro rookie and cant drive, ha ha) I bought it mostly for goofing around with at the house and in the grass and dirt.
On the road it handles decent, and great off road. With the way that I drive, the Revo flips over less and has a better stance. It seems to be more of a sport truck than a monster truck.
So far I have stiffened the spring rates. I put the #20 green springs from the rear on to the front and installed the #24 tan springs on the rear, which stiffins it up just a little bit, up from the #16.4 and #20 rear. It handles much better on and off road with less body roll and noze diving when breaking.
The electronics are ok, and I am in the process of researching a replacement for the radio, then possibly the steering cervos.
Hope that helps from a non techinical guy.
