The I have owned 2 tmaxxes, and I now own a Savage and MGT.
The MGT is my favorite by far. The Savage is fun because I beat the crap out of it, but the MGT spanks in when we are running around racing/chasing each other.
It jumps smoother, powerslides easily, and handles like a dream.
Right now my setup is :
Mach .26 engine
Red/Copper combo spring on front and rear
Maxximizer beadlocks x25s (offset) with Losi Zombie maxx tires
Fantom Pipe (w/side exhause header
OnlyBatteryPacks.com 6v pack
Forward only conversion
Last time I drove my truck, my friend hit me with my own Savage really hard in the tire/rim. The beadlocks are tough, becuase my top a-arm snapped.
It only broke because he was doing proabably 30mph and I was stopped.
hahaha
So right now, I have RPM a-arms in the front and stockers in the rear.
I might leave it that way for a while, I don't know, I haven't gotten a chance to try it out yet.
If you were to get the MGT, I would wait for the new one (with the bigger motor), or if you get a really good deal on one with the TT.21, I would run it stock until you can upgrade the springs and tires/wheels at the same time. After that, I would upgrade to the FOC. You will not believe how much weight and performance that this adds to the truck!!!
I forgot to add... I also put in a JR rs310 Rx in the truck to use with my JR xs3 pro
