you claim that it is because of the size, when in fact it is because HPI's are junk.


TC3 had some tourque steer due to the rotation of the motor and poor balance. Not because its diff had different size outdrives.
I have NEVER said that the TC3 had torque steer because of the diffs but because of actual torque steer that happens on any shaft driven car. I mentioned the pro3 only for that problem, and I'm not even saying that this car will have it because I do not know how stiff the outdrives are. Please do not make me say something I haven't.

oh,,, dont get me wrong.. I wasnt..

you just said that the HPI had tourque steer because of the different size diff halfs... and that this car may have the same problem. I merely dissagreed that different size diff halfs had less to do with a car tourque steering than your were making it sound.

thats all

Well, you could actually twist the long outdrive with your hands quite badly, not to mention the fact that it was in two parts and there was some very bad play. In any case that was not helping. I still didn't understand that thing about shafts of different length.

I know, i just edited my post.

About the steering I'm pretty much sure that the servo goes underneath the steering rack, with the servo horn facing the motor. That's pretty smart actually, the thing is I wonder how on earth they managed to have all this space to put all this stuff on the centre line. I guess having the diff pulleys out of the way helped a lot...

Let's see...one...I found an old (long) Pro 3 outdrive...if you can "twist" it, then you must either have really strong fingers or you must have a really keen eye.

Two...any "twist" (either real or imagined) between the inner joints of the axle isn't going to cause torque steer, unless it was severe enough to cause the car to turn (I would guess it would have to be more than several degrees). Even then, once it was "twisted" initially, it would "untwist" almost instantly as the torque decreased.

Three...the Front and rear pullies on the Pro 3 were on opposite sides...hmmmm....
(...wonder what happens with a one-way?)

Four...on "big" cars (the ones you sit in), the OE's use equal-length axles (among other things) to reduce or eliminate torque steer in higher-powered FWD models. They use an arrangement that looks (and functions) just like on the new Losi or the Pro 3.

Torque steer, in the manner that you are speaking of, as compared to the twist caused by the motor (see: TC-3, etc.) is caused on "big" cars by unequal length axles, and deflection in the drivetrain acting upon the axles...and "little" cars are not any different in that respect.

Cliffnotes version:
Long diff halves, whether twisty or not, aren't going to cause "torque steer".

They can't and they don't.

Default I have to say if your not Hara stay away from HPI

Just my opinion from the local guys here that run them. But is'nt this thread about the Losi. Wow look at all the scuttle that started from a couple of pictures that were never suppose to be taken and never suppose to have been posted.

Default Yeah it was awesome

But compared to a car like the TC3.
Just compare the cars resumes.
TC3 countless wins on a club and national level.
Any Hpi in the states not wheeled by Hara? Any wins.
