i agree with you Xanavi! all that Tamiya is doing is adding some optional parts and calling it a new release!! that is bull$h!t! there is no new technology or changes in the basic kit. they should just focus on "real" improvements and implement it in a totally new chassis!!!

I thought the TRF415MSXX just have added features from the TRF415 MSX MRE... And now they are making a TRF415MSXX MRE and not TRF416??? What are they trying to do??? Can't they just make a 416 now and not that double X MRE...???
plus it is more money to make for them... look at it on the bright side, we wont have to spent to much on the 415 for up grades...

Actually bro, we are spending more money cause if ever, we are just like buying a TRF415MSXX itself... Why make a TRF415MSXX MRE if the 415MSXX itself is a replica of the 415MSX MRE, just added some new features like the airduct system, the bumper holder, etc etc...

dont worry after they release this porn star it will be 416... then we will start the whole m ms pms xxxpms chit from the beginning
I would be buying a 2mil chassis inthe future for testing anyways except that 415 mre is just fine

Any two surfaces that come in contact with each other will create friction mate. laws of physics state that any force applied will create a force odf the same magnitude in the opposite direction.
so the the teeth are there to create friction so the belt doesnt "slip".
If you want no slip on your drive train remove the belt.
the belts we use are called syncronous Belts or timing belts (this is for people like me who cant spell the damn syncro word) For general in formation on belt systems you can read the documentation in the www.sdp-si.com web site.
and belts carry for on only one side. belts will have a slack side and a force side. belt tensioners have to be placed on the slack side to remove the slack. the tensioner on the force side will only reduce efficiency by increasing drag (friction)on the system which will result in premature failure of drive train bearings and belts. only belt guides are placed on the force side or where the added resistence is acceptable. (talking 2 pulley systems here)
so the so called tensioner is not a tensioner on the 415 but a guide. and what we do with the rotation of the bearing holders is called preloading. the 415 would be very efficient if we reduced some preload and placed a spring loaded belt tensioner on the chassis.
Of course best way to is to test it yourself. crank up the preload on the belts witht he bearing holders and try to rotate the tires. you will see it is very hard. it is because the preload is exceeding the drive train specs and causing excess friction on the system. (not only in the belt but in the bearings as well.) release and you will notice the systems works fine. if you can find a spring loaded tensioner and place is on the chassis you will notice that the systems is still smooth (not as much as a fully free one) but with out belt slack.
so to sum it up.... the more teeth the more friction you will have...

It says the TRF shocks are a new design. What else could they do to a perfect shock?
Other than that the rear brace probably just doesn't have that cross section, the one that pro drivers usually cut to give equal side to side chassis flex.
Also the top deck is different. Still looks awfully similar to the MSXX, although there will probably by Marc Reinhard Edition written somewhere on it.

Yeah bro... What's the big deal with those new added features...

i think it's called " Marketing Strategy"
so that you may pay more

I have a TRF 415MS LE chassis that i ran a max of 3 times before i broke the lower chassis plate at our local club. Been waiting for a chassis plate for over 8 months and finally got it.
I have added the TRF world champ parts but other than that everything is std as it came.
What would be good tweeks or tips for running with foam on asphalt in stock class ??
Any good base setups ??
