Our track would be considered med-high, low to med dust, and relatively smooth. I didn't like bar codes or suburbs for my B4, I used Pressure Points rear and Rips in the front or Dirt Webs all the way around depending on conditions. I have not had a lot of success recently with the PPs and Rips with my B5M but my cousin runs my old B4 and they still are okay on that car.

Hello everyone,

My son and I are new to this hobby. We recently purchased a B4.2 RTR as my son is getting a little more serious about RC racing. He had his first RC race last week and I'm pleased with how well he's doing also the reliability of this car. This car is really strong. I've made some small changes (more for reliability) The servo was replaced also the turn buckle ends. I've changed the shock oil weight (35w front) (27.5w rear) as he's currently racing on an indoor carpet track. Everything else other then tires is stock.

After reading approximately 60 pages of this thread, there's a lot more I need to read before I ask any questions.

Though I would reach out and say hi.

Hello Nels, I am new here myself and actually don't have a buggy yet But how is the car in your opinion? I have been trying to find reviews on it and I have heard people complain that the stock servo is sluggish and the tires suck but beyond that it is great to begin with.

Hey BundleOjoy, At first I was concerned with the fact that this model is already 2 years old. My thoughts were "how competitive could this car be" The shop owner suggested it to me as an entry level for my son, as he is still in the early stages of racing.

I'm impressed with this buggy. First this buggy is really strong! It's flipped end over end more times than a gymnast. It's hit walls while in a turn and continued to run. The only broken part so far has been the bulkhead.

I've replaced the servo and the turn buckle ends as I want to keep the car as reliable as possible. The servo is not very strong and can fail if hit. (so I'm told) I have several sets of tires for different track conditions. I also changed the shock oil weight for his current track setup. Other than that everything else is stock.

Over all, I think this is a really good buggy. Hope this helps.

Hey guys I want to try something with my b4. There is a sale on a 5mm peice of carbon fiber perfectly sized for a b4 chassis, I want to try buying it and making a custom chassis, anyone tried this? Or do you think this is a bad idea

Honestly, the Associated RTR cars are among the best RTR's on the market.

The issue for anyone looking to get serious is the costs involved with making it the best possible race version because it WILL cost much more to upgrade to what you'd get out of the box and bought the appropriate electronics for it. Going this route you'd have ALL the car you'd ever need at your disposal and you control the power output to suit your growing skill level which can be as minimal as just swapping to lower turn motors as you go.

Having said that, if you've already bought an RTR and are happy with it, replace the crappy negative response time servo with a good one and get a motor suitable for the class of racing you will be partaking in and enjoy.

It's not a bad idea, but it isn't practical. The work involved in making it might not prove worth it in the end. If you were to do it, I would suggest you change the width to match other, more narrow cars because this way you won't have to worry about side ground clearance which is why the stock 4.2 chassis angles upward on the sides.

I would look to something like the YZ-2, RB6 or any other narrower design that still has lids being produced. If you can copy the RB6, it might be best because then you could add the side plates to help stiffen up the chassis and have real estate for velcro mounting the lid.

Also the front of the 4.2 chassis angles upward so you will likely have to have a piece of 7071 Aluminum pressed at the proper angle with a stepped bottom to maintain a smooth line on the bottom of the chassis.

I know this is the Associated B4.2 thread but to offer another option to those looking at a quality RTR Kit, this just came across my E-mail. I run this for 2WD Stock class and it is easily one of the best quality kits I've ever assembled and the fit and finish of components is superb. Even better it includes both MM & RM options which is astounding for a RTR.

Is it appropriate to show off your ride here?
Been working my B4 slowly over the past two years.....
Thx

No ones stopping you

How is the b4.2 RS???
My cousin has a b4.1 rtr just for bashing with a little racing, and he loves it. Can you still find parts for the b4.2????? I am looking at getting one and selling my rusty vxl

Parts are still readily available for the b4.2 and should be for a long time.

Can anyone give me some help: what kind of upgrades are most useful? I already changed the Servo and ordered some turnbuckle ends (RPM)...Are the big bores fully worth their price?

Absolutely, especially over the RTR shocks.

Mmhh okay.
Wasnt hoping for that Info. They are quite expensive here in germany and dont come with springs, so we're talking about more than 100$ just for "an upgrade"
Can anyone tell of the stock-carbon A-Arms are worth the upgrade? I could get them in my shop next door right away
