I have the same setup as zombie too. I finally managed to get the front one piece bevel shaft too. I tried installing the one piece in the rear too but couldn't figure out how to put it together. I ended up just using the spur gear from the Hara kit instead.

I'm still waiting for the 18mm heavy duty ball cup from the Hara kit. That should be available from Tower Hobbies soon. That's the last thing I need to update my Pro 4 to 2005/Hara specs.

Does this allow the spur gear to be removed easier? For example, on the Yokomo MR4TCSD, the spur gear is quite simple to remove. However, I find with the Pro 4, you have to take off the whole upper deck. Not that I normally change spur gears, but it's just a good thing to have.

I don't think so, it's basically the rear input shaft and spur gear mount just in one to stop any play or wobble you might get with the stock parts.

not only is it a single piece in the rear, it gets rid of the e-clip and uses a screw. it weighs much less, and it eliminates all but 1 shim (iirc, may be more than 1 left but most of them are eliminated), it uses a solid pin, not a roll pin (which can get bent easily).

basically its infinately better than the steel 2 piece design whether its better than the shaft with integrated bevel gear idk! my plan is to keep it in the rear and use the integrated bevel gear front shaft

I'm hoping someone can help me. Lately I seem to go through a set of front gears every race meeting, even though I'm running the 1.1 gears. I have the gears shimmed as per the manual.

No doubt somone might say to stop hitting things, but I'm no Hara, so hitting things is inevitable.

What can I do to stop stripping gears out? Is there a better shimming arrangement? Is there something I should be doing to the gears?

The Pro 4 IS a "modern day car".

Some think shaft drive cars are better for stock / 19 Turn (better acceleration) and belt drive cars for mod because they have smoother acceleration (low turn mods ie: 10 turns or lower).

Not sure where you've been hiding... but the Pro 4 is, and has been, one the top touring cars in r/c! I'm still wondering who does the voting in the Car Action magazine for top on-road vehicles?!? Maybe, someone can tell me how Associated touring cars win the electric AND nitro catagory every year? Not saying they aren't very good - they are, but the best?... I don't think so.

If, the car is new and you assembled it correctly, it should not have any tweak. Question: Did you mistakenly, put the left 4 degree c-carrier (caster block) on the right and vise-versa? This would definitely cause your car to have a large turing radius.

Thor,
check your steering End Point Adjustment on your radio, too. You may need to increase the value to get full steering throw.

Yeah, I saw that too. I immedietly threw the mag in the trash.
The B4 and T4 I was willing to give them because it is a 50/50 flip between AE and Losi cars.
But best TC??
That mag is purchased and paid for by AE. There is no question.
Top Five tourers in no particular order: Pro4, T1FK05, RDX, YOK (SD or BD), 415.
Notible mentions: JRXS, Sigma, Alex Racing etc.. etc..
Oh, yeah a very distant 10th, behind the TT-01 would be the AE car
ok, I'm just joking...9th.
I know it's readers choice and not "best", but who did all the voting, the staff at AE?
