What's the difference between the xxx-t CR and xxx-t Matt Francis?

It seems the MF2 has all graphite, and all the updgrades, but why is it $5 cheaper?

I'm trying to figure out which one to buy! Help!

Actually, the MF2 is normally mroe expensive. The XXX-T CR is $250 at my LHS and the XXX-T MF2 is $255. The MF2 is discontined by Losi though. The graphite is stiffer than the EA3, but the EA3 is lighter and the CR chassis is longer which is better for rough tracks. The MF2 seems to be more durable. Like if you break a part just repalce it with graphite and your set. The Gen 2 tranny was a failure so Losi went back to the gen 1 trwnny on the CR. Overall, if you want to race and bash go with the MF2. There are still alot of MF2 trucks on ebay and people who still prefer the MF2 over the CR as they were extremely popular when Losi made them. But if you want hardcore racing, go with the CR.

So, if i decided to start doing some racing with my XXX-T graphite, do u think if i bought a XXX-T CR and used the chassis, rear hubs, and a few other parts and replace them with my graphite parts, i would have a ideal race truck, correct? What do you think?

Really, all you need to be competative are graphite arms and shock towers and xxx-t cr chassis. The rear hugs on the CR break more often.

Where are you going to be racing at?

The brushless version int much faster. It is like a 13,5/17.5 novak motor with plastic endbell and small bearings. Bascially cheaper. I would get the brushed and put a better motor in it.

It comes as a KIT, no motor, electronics inclued and you have to build it. A good tranny doesnt need metal ears. The only reason Traxxas uses metal gears is becasue of thier horrible trany. Ball diffs are more sensetive though. If you are running on 6 cells it should hold up, but I wouldnt guarantee 3s lipo.

Are the a-arms on the high roller the same as the ones on the xxx-t. I saw some metal a-arms, but they were for the high roller and I have a xxx-t.

Might as well put this info in this thread incase someone trys to look for the info. They might not make another thread.

Metal gears for the XXX-t trans.

idler:
http://www.losipartshouse.com/servle...l-Idler/Detail

diff:
http://www.losipartshouse.com/servle...um-Diff/Detail


Course, I've already switched to the Losi Desert Truck gear diff but if I want to go back to a ball diff, I'm getting these.

And speaking of the gear diff. If anyone wishes to make the swap. Heres whats needed.
***This is for the GenI trans. The Black gearbox***

This is at losipartshouse.com.
sku# LOSA2919
Transmission Case, Diff Gear Only: DT
$6.63

sku# LOSA2930
Diff Set, Complete: DT
$16.59

sku# LOSA6230
Shim Set:3/16,1/4,1/2
$2.48

If you have some small shims laying around the house already you probably don't have to purchase the shim set.

Use the owners manual for the desert truck to show you how to build the diff(don't forget the shims in it! I did and had to go back and put them in after a couple of runs because the gears were slipping)
http://www.modelflight.com.au/manual...ruckManual.pdf
Add some oil or grease, probably have to try a varity till you get it the way you like it. You can search around and find what others are running for weights or types of grease too. The thicker it is, the more "locked" the diff will feel. To thin and just one wheel will spin under acceleration or a hard turn.

Everything else will swap over from your old tranny. Bearings, idler, motor plate, drive shafts etc. The bolts are a bit short (about 2mm)but if you drill out the holes in the tranny case just enough for the head of the bolts to counter sink, its fine. Assemble it all back into the new gearbox case and put in the truck. Some people have said they needed to lightly sand the rear shock tower and pivot block to get the gearbox to slide in but I didn't have to, so that might be a case by case depending on how well the molding of those two parts are.

Hey guys I got a xxxt sport 2 off here and installed my own brushless setup in it. But the tranny keeps wanting to lock up. I tore it apart it needed grease so I did that and it felt really good. When I put it back in though it keeps wanting to stick. Any suggestions?
