To all you guys out here. You see, a shaft is just a hype.
I personally think the 414M has still the better symmetrical design over this 415.
Some people where fooled by the Tech Proto:
Some people said It could't be Tamiya becouse Tamiya make their own parts.
Wrong becouse the first 414's shared a lot of Atlas parts.
The funny thing about this (nice) looking proto is if it had one more gear it would be simmilar to the TA03 transmission.
Ofcourse with much better quality, less play, less friction, ect.
The bad thing about this car is:
To take advantage of this design they should make the pully's a lot larger for less belt warp becouse they have the same diameter front and rear.
The advantage of a transversal motor is you use its movement to push the front of the car down. When your motor turns to right,
the motor can wants to twist the other direction and pushes the front down. with this proto the motor turns the other direction (they should have put in another gear like the TA03) wish is not so good.
Now for the real thing.
The TRF 415 looks a lot like the Tech Racing MY02. The Yokomo MR-4TC is different becouse the front belt is not in the center
and the Atlas YM-34 is different becouse the motor sits flush with the bottom of the chassis.
To me the Atlas looks a lot better than the Tech Racing but the Tech Racing had some really good results in Japan. I think the centered front one way has something to do with it.
The TRF 415 chassis is milled under the motor like the Yokomo MR-4TC SP YMP. The Corally has nothing to do with it.
See and compare!
The Yokomo MR-4TC SP YMP:
The Atlas YM-34 Type Si:
The Tech Racing MY02R:
The Tamiya TRF 415:
Tamiya wanted to put the weigt more in line like the TB Evo3 and make it as narrow as possible to allow more roll (look how close and thin the right side of the chassis is).
The centered front one way means you can't use a rear diff in front so you need more different parts. Still no countersunk upper deck and sock towers.
To me the best belt design is still the HPI RS4 Pro 3.
