Is there something wrong with that statement or is it "normal"?
I would have thought when you brake you get 4 wheel brake...

This being my first 1/10th scale 4wd buggy, I am a newb...

Thanks!
It sounds like the car has a front one-way, you might want to take a look inside the diff case to make sure. Initially the car came with a center shaft one-way, and we later moved to a direct shaft setup. The front one-way was used by those who wanted a lot of steering.

So how do you guys feel the BJ4 no WE stacks up against the XXX-4 G+?

With the Worlds front bulkhead and arms, the car is far less fragile then the Losi. It really comes down to if youre running other vehicles from AE or Losi though...

Yeah, I'm pretty much all losi. The only issue I've had with the XXX-4 is throwing belts from time to time. If you throw a belt and then shred it, it's a real pain in the ass because you basically have to dissasemble the entire car.

I've only owned one associated car, a B3 FT that I have collecting dust. Amazingly, I'm pretty sure it would have no problem competing today.

Took the BJ4 out to the track for the first time last night.
Only broke 1 arm and had a blast!!!
Ten minute main was incradible too!!!!
I do have some learning to do, drives alot different compared to the T4!

Great product!!!

Going to put the B44 steering rack on it this week!
BTW the arms are soooo easy to replace in a snap!

I had a blast with the new set-up, but this thing has WAY too much steering!
When I threw the new steering assembly on I noticed it has a one-way on the center shaft. Is there a standard non one-way piece to replace it with?
I tried to get some of the steering out of it and was pretty much unsuccessfull, any ideas?

If you dont have a manual i can get you the p/n when i get home.
Does it also have a front one-way?
If you don't want the center one-way i believe you need p/n 1045, Its the direct center shaft kit.

What Lipo Tray are you using Linkster? By the way, will the AE TC5 cf batt strap fit the originial BJ4? Cheers

Hey Andy,
There is one guy at my local track who drives a BJ4 worlds and every time he strips a ring and drive gear he rebuilds it then puts a ton of diff lube one these gears. And the few guys that i talked to said they are self lubercatin gears. I let this person use my brand new diff lube only been used once and know my diff lube if almost gone. Now my question is do your really have to use diff lube on your ring and drive gears. I know you used them on the diff balls but i dont know about the gears it self. Let me know, Ty

Just looked. No. The BJ4 was set up for 7cells, to allow for battery movement. The TC5 is only set up for 6 cell spacing.

Not Andy, but.
Sounds like the diff is too tight. Or he is hitting a lot of stuff. You don't need to put lube on the gears.

He has it to lose IMO, I can slide the diff side to side when its all put back to gather.
