Jimmy411 is wrong. The B4 is a very good machine and quite strong and resilant. I have 2 and the oldest one is like 9 or so years old. I bought it the day the team ones were released.

Now are you looking to race or bash? That will change everything.

If you want to make it handle like nothing else buy an X-6 conversion. I converted my 3rd one and it is amazing. My son and I race a lot and the B4 and X-6 are our go to buggies.

I don't race, just practice laps. On a good day ill run 6-7 packs. (45 mins run time each) and I have broken every single part on my b4 including 2 chassis. Shock towers and arms seem to be my most frequent. So I'd call the b4 pretty frail.

My local track usually has some messed up sections like bigjumps after a sweeper that have either a pole in the middle or. A short landing with a pipe and a hard 90* turn.

Thanks for the info, I'll look into the x6 conversion.

To answer your question, it'll be a basher, but not to be broken on purpose. I like high speed jumping and I want some really, really high speeds. The car has actually been exceptionally durable given the abuse it has received and having no true upgrades as of yet.

I am most interested in recommendations on servo's, lipo's and the motor/esc. The car will be mostly metal so durability will be the name of the game.

Thanks again, anyone else care to comment on what to put in the drivetrain?

Which sounds like a typical rc car track.. ive been racing for about 2 1/2 years now and race 2 sometimes 3 times a week with my b4.1 and either b44 or t4 and rarely ever break like that.. yes you are going to break your occasional a-arm here and there or shock shaft, shock cap or caster but that is going to happen with any car you race. Traxxas bandit is one of the most durable 2wd buggies around and even they break a ton.... Sounds to me if you are breaking shock towers, 2 chassis, maybe 2wd buggy is not for you, because apparently you are landing upside down or casing jumps pretty bad. But to blame it on a car that has numberssss of championships and to call the b4 frail i think not.

I used to think my B4 was frail.


Then I learned how to drive it.


Speaking of my B4, I need some help with it. We're going to say its stock, and several years old. Problem is, I can't turn at speed. Going down a fast straight I can crank the wheel a little or a lot, doesn't matter, it'll just creep over in that direction. As soon as I let off the gas it'll hook and whip around like crazy. Ribbed tires up front, pins out back.

Is this the nature of the beast or do I have an issue with my setup?

What do you guys think a B4 Rtr with a brushed setup would be worth? It is setup to run in a vintage class I was told. I got it on a trade just looking to see where I should start a price when and if I go to sale. Thanks guys

What kind of brushless set up is in it? Stock? Extra tires? Extra parts? Aftermarket accessories on it, such as shocks, steering crank, hubs?

I have two questions:
What should a B4/T4 be geared at for a Tekin 10.5T motor (I have both but they were last used with the LRP Sphere which is now fried.).

Is the B4/T4 updatable to the modern slipper assembly, used on the B4.2/T4.2?

1) Gearing for a B4 with a Tekin 10.5, I start at 26/75 and gear up or down from there depending on if I need more power, or acceleration.

T4 I'd start around 22/81 and do the same as above.

2) Yes it is updatable, all B4/B4.1/B4.2's use the same top shaft.

I'm picking up a used T4 with the posi-lock quick release axles. Are they any good or should I get regular CVD axles for it?
