Yeah, but there is not a part number to buy a complete diff AFAIK. So you need to buy all of the parts individually

lots of play at the arms and uprites ...it would have been nice to have replaced the molds a bit sooner.

I ended up replacing the f&r hubs with the Square units, that seemed to help with some of the slop.

Yeh, around 5.6 should do it. We actually race with these motors in our F201s and they fit really nicely with the high speed gear set which gives you 5.88. Obviously it will depend on what type of track you are running but you should be around 5.6-5.8 with the Tamiya 23T motors.

Also, regarding the dirt, I don't think you have built it wrong, just may not be tight enough?? I'm not quite sure but I certainly get a lot of buildup of dirt on the bearings for the diffs on the outside of the bulkhead. Nothing that a bit of compressed air can't fix.

If you could get some pictures to us of your bulkheads with the amount of dirt you are talking about getting, then we'll be sure to take a look. I honestly don't think its THAT big a deal because some people don't even run with the gear covers and they don't have TOO many problems.

I was using the original 34T pinion on all Orion Rush 17T, Tamiya TZ 23T and Tamiya Modified 11T. The gear ratio is actually 6.07. But all the motors are very hot after 3-4 min. As i am a newbie to racing, i am not really sure whether that is overheated or not. but at least, if you put your fingers on the motors for 3 seconds, you will feel unbearable. I am going to get some pinion to put down the FDR to 5.58 and see how is that going.

About the dirt, I just cleaned it last night and rebuild the bulkhead according to this article:
http://www.taobracing.net/review_evoIV.shtml

i am pretty sure the screw are tight, but maybe i did not tighten them properly. but that is not that easy to make it balance at all sides.

and what I did either is put some grease on the gap from inside the bulkhead to prevent the dirt from coming in. i will open it later when i do the maintainance to see whether it is alright or not.

Thanks you all

go get the pinion tomorrow and try, then go to the race on sunday, my virgin racing..............

Default e4 - old suspension

pizzadude,

the old suspension on the ev4 really does not work very well. the front arms really increase the angle demanded of the universal, causing the car to shake like mad during corning.

Default new arms

Hi stefb

Those arms are not available they were special one off designs for dave jun to try. He designed them and had them made up for him to try at the worlds. No word yet wheter or not he liked them or not.

Wow, those arms are sweet. I don't quite get the L-shaped knuckle though. Are those special ones that Surikarn was running at the worlds?

Superdate, I would agree that 5.6 sounds like the right ballpark for the 23t. If you are using a 90t spur than you want a 37t pinion to get you to 5.58 or as an alternative, a 36t will get you 5.74.
