I have an "original" BJ4, with a upgraded front end with BJ4WE bulkhead and front arms. I don't plan to change any time soon. Standard stick size lipo's fit, parts are interchangable with my B4 and TC3 (yeah... I still run a TC3). As the previous boys said, there is very little (if any?) difference in suspension geometry to BJ4WE and B44.

I have a 1st gen BJ4 and I LOVE it!
It has Losi shocks, Lipo Tray, Double Front Shocktower, Aluminum Rear Hubs, and I have a set of aluminum rear a-arms to use when I feel like it.

It is just plain awesome, I drive it HARD and it just keeps coming back for more.

Woohoo! I just bought one, finally!

Now the fun part, setting it up.
As far as 4 wheelers go I am a newb.
Does anyone have a good starting point "baseline" set-up for the old school "non-worlds" buggy?

Also what wheels fit this thing? Losi or associated or both?
I would like to get some of the J-Concepts rulux wheels.
I have them on my T4 and love them!

Thanks!

Cant wait to get it!

Congrats on a great car! Now that LiPo has taken over I've seen several people do well with the side-saddle cars.

All you need is the B44 front hexes to run the rulux wheels

Finding this took some effort

You could also just run some of the current setups for the BJ4WE

Thanks a ton!
I looked on J-Concepts site and found jack squat!
I will swap on the B44 front hexes so I can use the rulux wheels!
I will also have some B44 setups to keep in mind as well!
I have seen the BJ4's on the track, thats why I wanted one, they looked good!

A good starting setup would be any of the current B44 setups. I run Maifield's Worlds setup on my non-worlds BJ4 and is a great starting point. One thing, make sure you pick up the .81" B44 front shock shafts. It will give you a little more front down travel and take some of the twitchiness out of the car.

hello sir, maybe you can help me with the gearing of the BJ4. Using a
GTB 5.5 with stock spur, sub-c power packs. Running it a med-large track loose sand
/soil combo. what pinion? any tips on the set-up? shock oil, shock position and tires to use.

TIA

Thanks for all the help!
I just got it today and am setting it up right now.
Somebody suggested the B44 0.80" shock shafts for the front to give more travel, but I noticed if there is more travel the front cvd's will be likely to come out of the drive cups at full droop. Just an observation.
Great looking and well put together buggy in my opinion!
Do people "double up" front shock towers on these like the Losi XXX-4's for more durability?

Thanks all!

Mine has a doubled up front shock tower and i think it is probably a good idea to do yours as well unless you want to carry a few spares.

There is a BJ4 local to me for $150 that I was tempted to buy.

I didn't know that they used stick packs.

1 more question: I got my electronics and what-not installed. I noticed when I give it some "gas" on the stand and brake the front tires continue to spin freely. Also when I try to turn them backwards they lock up and dont turn.

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!
