Questions?? J Concepts BJ4 "Non" worlds

Hey everyone,

I looked for a thread about these but was unsuccessfull.
I have 2 questions about this buggy.

1: Why are these so hard to find?

2: Pros and cons of this buggy versus a newer model (ie Kyosho Zx5?)
Just want a 4wd but dont wanna have to buy more lipos...
(saddle packs that is!)

I know the newer version (worlds edition) is newer and better, but I have stick lipos and dont want to invest more change on saddle packs. Thats about it.

Thanks!

I know you used to be able to buy one right from JConcepts web site but I looked and don't see the BJ4 on there anymore either so my best guess would be ebay.

I was in the same boat you are in!! I didn't want to have to buy saddle pack lipos when I already had enough stick packs to do me. But I never found one that was clean enough for me so I just broke down and bought a B44 and got lucky and found some Yeah Racing Lipos which work real well.

I have one for sale right here:

http://www.rctech.net/forum/r-c-item...0-shipped.html

I bout this a year ago and replaced the diff cases, bearings, and rebuilt the diffs and shocks. I have raced off and on for almost a year and have only managed to break a couple of front A Arms during that time.

The only features about this car I found lacking are that it doesnt have a built in servo saver or dual slipper clutch pads as found on most of the newer cars, and its not as easy to work on as the B44 (the steering rack is not cauptured for example).

The obvious upside is that I didnt need to spend $200 in saddle pack lipos and changing the battery is easy.

They are getting hard to find because they stopped making Non-Worlds edition BJ4 kits a few years ago. But, parts support is surprisingly good. You can get any part you need through Tower, Horizon, and JConcepts.

Sweet! If I dont end up winning the one on ebay, I will look you up! That is if you still have it... Thanks!

What would be sweet if they made a stick pack variant of the B44 but that would be just too easy!

I've been running the original BJ4 for the last few months with no problems. I bought it when it was first released a few years back but I could never get the batteries to stay together. Regardless of how I soldered the cells together, they would eventually come apart from all of the chassis slapping. Anyways, with Lipo technology becoming more available, I strapped a 5000 mAh Reedy pack to it and it's all good.

It does lack an integrated servo saver, but I was able to install the B44 one, here's the link:

BJ4 to B44

As far as competitiveness on the track, you may give up a little to the updated geometry of the newer cars. Unless you're competing at the national level, it's still more than enough buggy for club racing and regional events.

Let me know if you have any questions.

The geometry has changed little or none from the original car to the B44. The difference is in the weight distribution, slipper, and ease of wrenching.

That servo saver/captured steering rack is a awesome upgrade for a BJ4!

I wonder if anybody has figured out how to put a B44 spur gear and slipper pads on a BJ4?

I never lost a battery out of my BJ4 becuase I was able to cut out and install a battery tray from a TC4. Its a direct bolt on part.

A lot of the top race cars, including the Kyosho, have switched over to, or about to switch over to, saddle packs to improve handling. But, I've witnessed a lot of guys put the beat down on me and other B44s with XXX4's, which are still wicked fast, so maybe saddle packs are overrated.

All I know for sure is that I got 2 4wd buggies right now and all I need is 1.

Actually I am high bidder so far and I hope it stays that way! Nice buggy! I hope I win it!

I am picking up my D8 tomorrow from my lhs so it would be a great month if I won it!

Thanks!

Andy isn't kidding about that... When I transitioned to the B44, I had a B44 and a BJ4WE next to each other for a while. From about 10 feet away, I couldn't really tell the two cars apart other then from the different paint jobs I had for each of the buggies.

I even transferred the suspension setup that I was comfortable with on my BJ4WE to the B44, the B44 ran like my old BJ4WE...

There were definitely worthwhile improvement that were incorporated to create the B44, but the suspension geometry is identical!
