TRF501X/416 Puleys 18T
HB front belt 169T
Xray rear belt

Now my question, because i have not much tracktime to test:

Is it always a benefit to lower the internial ratio? or depends it on wich class you run (mod or stock)
I run the car in 9,5BL 5cell/13,5BL LIPO classes.

Thanks in advance for some answers.

Greetings Blueman
dont worrie about that i race with 10.5 BL with a TRF415MSXX and i use stock internal ratios and use 98/48 which gives about 4.17(ish)/1 and i can keep up with the 13.5BL lipo boys with Xrays

I think also that the difference will not be much, but i read (i think in this thread) that a lower internal helps the car to get faster on topspeed when you accelerate out from corners. compared to the higher internal, when the alover ratio is the same.

Has anybody further expirience in this stuff?

we have noticed with brushless motors this year that the cars reach there top speed in about 70 to 90 meters of accelaration on our back straight

the brushless motors used to wind up more slowely usually reaching top speed half way down our back straight

The brushless motor has not as much torque i find as the brushed motor but find it revs well so keeping speed throught the corner is REALLY important

my TRF can keep up with the Xray009 and the Hotbodys through the corners and down the straight , just my driving skill lets the car down !!!

Does anybody have anything for extremely small parking-lot outdoor asphalt, specifically on the MRE & MSXX cars? I checked the list of setups in the link provided, but we absolutely cannot run spools on our track. I've always run with a front one-way cause the corners are so tight and low-speed.

The MSX-MRE kit setup works decent with the front one-way, but I'm sure it could be better...

usually tight is where a spool works better, high speed flowing corners is one-way

Default IFS for the TRF??

Why don't the TRF cars have the IFS suspension??? I thought the IFS was a new a better design. Have the racers found that it isn't better, difficult to tune???

I am looking to get a TA05-IFS, but is it a waste of money? will the normal TA-05 be a better performer?

Only difference is the body you can run, IFS allows the bodies with lower front ends on them.

If you get a TA-05, either reg or IFS, do yourself a favor and get the 'R' version shocks alone worth the price difference.

If you buy used look at it carfully, I see a few on here that aren't true 'R' version even though the person lists as such

I think a lot of race events don't allow IFS bodies because their not ROAR approved and in club racing they say it's an unfair advantage because the bodies only works on Tamiya IFS suspension and not any other car MFG.
Just a guess!

Put in a front diff and run a similar setup to a T Hard carpet rubber setup , the diff will make it easy and predictable to drive which will give you consistant lap times.

IFS bodies are for looks only. They are meant to mimic real life touring cars with hood lines so low that they actually dip down between the front fenders. Unfortunately the aerodyamics of a 1:1 car do not scale down, and your typcial touring car body is going to provide far superior downforce for both front & rear. This is why your typcial touring car body is illegal at Tamiya TCS events. If they weren't, everyone could only run the Tamiya Legacy B4 to be competitive...

In addition, the pushrod suspension actually adds to the complexity creating room for more slop. Instead of two ball-joints per shock, you now have 4, plus a ball-bearing and rocker arm. This does adds considerably to the unsprung mass of the car (even though it may not seem like it).

Sometimes slop is good.... it gives nimbleness to suspension.

( btw, I still prefer normal shock though ...... simplicity is better for me )
