Interesting... MST is using Tamiya bodies on these things... ... Edit: Now that I'm actually looking at MST stuff it seems like they use Tamiya bodies on multiple rigs, not just these rally cars.

The transmitter seems to work fine, but feels very cheap. It has something loose inside... It feels like one of those little cans that moos like a cow when you turn it over...

The manual is very basic; totally functional, but not the best.

It's an RTR so there's not much in the way of instructional steps... One of the only things it tells you to do is cut this little plastic corner off. I can't really figure out why.

I really like the stance it has out of the box. It's a bit taller in the front and a bit shorter in the rear.

Love the gull-wing arms!

The suspension travel is badass.

The shocks feel great; extremely smooth out of the box.

When you drop the chassis on the bench, the front has a bit of bounce back. It actually looks nice and scale but I might try some heavier fluids in the front shocks.

Spring rate seems good for the stock weight.

I plugged a pack in and realized the the gear mesh was horribly loose. Then I noticed the motor was pretty loose as well...

The upper chassis brace makes getting to the motor a bitch. Lessons learned... It's always fun discovering the quirks of a new chassis.

The rtr servo isn't too terrible, but I'm used to a bit more speed...

Savox 1258 it is...

Both the stock servo and the savox use a 25t spline. So I just put the stock servo saver on the savox 1258.

It is hard to compare it to the xv-01. I'm really not the best guy to describe driving characteristics of any given car. With that said, I do like the xxxr. I like it a lot. It's definitely different than other cars, but after a few packs it's super fun. Time will tell i guess.

The XXXR comes with ball diffs front and rear as opposed to the xv-01 that uses gear diffs.

This gear diff should work on the XXXR ...

XV01 for sure. I know it the best. I have multiple xv01s and lots of parts. I can diagnose problems quick. Also, most of my buddies run them which is always nice...

The MST is new for me. I like it a lot so far. Excluding bigger cars like DRX and WR8, the MST is the best RTR rally kit out there. No doubt about that. It's a competitive little car for our style of racing. And it's only $300 RTR...

I'm thinking of getting this. I've owned two xv's, a pro and a long damper kit. Would this feel like a downgrade and do you think the ball diffs are functional?

I don't have good luck with ball diffs in rally cars... Last night I ordered the gear diffs (part # 21028.

Overall this car is really nice. I wouldn't call this car a downgrade from an xv01. It's certainly different though.
