Like our Team Associated B5M weight reduction program, we took our B6D and put it on a diet as well.

Beginner’s Guide to RC – Reducing Weight on your Team Associated B6D for Stock or Spec
Class Racing
A few months ago we took our Team Associated B5M and put it on a diet, pulling the bulky parts off and installing
lightweight replacements. The goal was to get the weight down a bit so that the electronics didn’t have such a heavy
car to push around; the lighter the car is, the faster it would be. This actually turned out to be a very popular article,
so we thought we’d do the same thing with our B6D.
The problem we found is that the B6D is already pretty light and, while we were able to find some weight-shedding
parts, the final outcome was not as impressive as it was with our B5M. The biggest difference, however, was the
weight we saved on the drivetrain; this alone was almost half the savings. This means that even though we didn’t
save a lot overall, we did reduce the rolling resistance, thus adding a bit more spunk to our 6-series buggy.
So, let’s get to the fat burning and I’ll share the track results at the end of the article.

2. Titanium Screw Set
Titanium screws are an easy way to reduce the weight on our B6D – it’s as easy as removing one steelie and
replacing with a pretty Titanium one. Singly, you’re not going to save a whole lot but, as an entire set, you can
actually save quite a bit; we pulled .66oz off our buggy. That’s a good chunk to start with!

Schelle Racing Carbon Battery Strap
The original battery strap was surprisingly light compared to an aftermarket one like Schelle‘s carbon fiber
replacement. However, it does save a little bit of weight and, well, the carbon fiber looks so much better. I might be
able to reduce the weight a tad more by replacing the 3D printed battery stops with short aluminum posts, but for
now it will work just fine.

4. This modification is actually something I saw at the track the other day; a stock racer had removed the thumbscrews
and steel battery tray shoulder screws and replaced them with long Titanium screws. So I thought I’d give this a look
and see how much weight this saved. As you can see, replacing these parts saved .14oz, pretty good for just a few
small parts. The screws are long enough to thread into the chassis quite a bit so they shouldn’t come loose. One
thing to note, though, is that I swapped out the original B6D thumbscrews for the ones used on the B5M. The
originals were just to small for my sausage fingers; the B5M ones were much easier to deal with. Your savings here
might differ.

Titanium Turnbuckles

5. The B6D comes with a sharp looking set of chrome turnbuckles, much better looking than the black ones all the
other Team kits come with. Swapping these out for Titanium equivalents is an easy way to save weight. I actually
had another package of Lunsford Racing‘s Ti turnbuckles here from my B5M build and after matching them up to
the B6D links, found they would work just fine. Simply remove the old links and screw in the new ones. Excellent
upgrade for a total weight savings of 7g.

6. Ok, I know what you’re thinking; .04oz? Yes, it’s a teeny tiny bit, but savings is savings. Remember what I said about
the small things add up – this is one of those small things that adds up. Plus they look cool, so you get extra pit
points.

Transmission
6/10

7. The Team Associated B6D comes with AE’s new 3-gear transmission – the best of the best – or so everyone
thought. Then a few adventurous people dropped in the B6 Laydown Transmission, thought to be optimized only for
high bite carpet situations. This optional transmission completely changes the handling of the B6D, potentially
leaving you off the pace without it. The conversion uses most of the parts from the original transmission, however I
did include a few other goodies to lighten the internal rotating parts.
I started by adding RC Speed Secrets cut B6 transmission gears. Original gears are machined down to remove
7/10

8. some of the gear surface. This reduces the amount of friction, thus allowing more speed. The overall savings by
adding these two parts is only .6oz, but the real savings will be when you pull the throttle.
We also added Schelle’s Nova Lockout Set, essentially removing the heavy slipper clutch system. This setup gives
the buggy better acceleration and a much more aggressive feel, however it is really recommended for the advanced
driver that has proficient throttle control. Try at your own risk.

Lightweight Body
Probably one of the best weight loss options is to replace the stock body with a lightweight version. This removes
8/10

9. some poundage that sits high up on the chassis, reducing body roll in the corners. As you can see, the new body has
a full paint job as well as stickers and it’s still almost 13g lighter than the stock body. JConcepts has quite a few
lightweight versions in their inventory; this one painted up by the one and only Larry Genova of Kustom RC
Graphics. This guy is the guru of pro painting.

Like I said before, the B6D is pretty light to start out with but without any major work (milling the chassis, etc), we still
saved a tick over 64g. I have to note, however, that since front wings are all the rage right now, I did add one to my
B6D. This added a bit of weight back on but I’m still doing some A/B testing to see if this is something I’m going to
stick with.
To test the performance, I skipped on over to my local testing grounds, OCRC Raceway in Huntington Beach. I ran
on the same track layout for both the before-and-after tests, using the same tires and sauce regimen. Let’s see if my
B6D can put in some better lap times in it’s lightened state.
Day 1
The first full day of testing, the B6D put in some respectable lap times, running low 20-second laps consistently with
a fast lap of 19.7. The later on in the day it got, the faster the track got – that’s when I could pull off the high 19-
second laps.
Day 2
Day 2 testing involved all the changes made to the B6D, all at one time. This was a bit overwhelming; I’ve heard just
installing the B6 Laydown Transmission can radically change the handling of this buggy. That being said, the first
battery was more of a reconnaissance run; feeling out the changes and gathering data on how this lightweight
buggy works. I’ve got a lot to share…
In this new form, the B6D has an amazing amount of steering. Installing the laydown transmission not only moves
the motor forward on the chassis, it also moves the battery forward as well. This shifts the static weight WAY
forward, so the B6D feels like it’s now rotating heavily on the nose. Add the extra downforce of the front wing and it’s
a bit overkill on the steering. The first couple laps were in the high 21’s as I struggled to get a grip on the car, but
once I found the groove and understood how it handled, I was able to click off quite a few high 19-second laps.
I also noticed that the acceleration was quite a bit snappier. There’s a jump in the middle of the track that’s right after
a tight hairpin; take it tight, you’re not going to make it; take it a little wider and you can make it almost every time.
With the new, lightweight transmission parts, I could make this jump almost every lap with a mid-tight turn,
something I couldn’t do before. I also have to give props to the Schelle Nova Lockout; this part completely removes
any slip in the drivetrain and provides instant acceleration. If you run on a high-bite track, this upgrade is a definite
improvement.
But here’s the rub – once a bunch of other people got on the track and started kicking some dust around, the B6D
got harder and harder to drive. This had me working extra hard to keep the car from spinning out, so the lap times
started to rise. This required me to do some suspension massaging to fine tune the setup and get the lap times back
down, but I think for my particular driving style it may take a few more sessions to figure the car out.
9/10

10. So, was all this worth it? Since I’m really only saving around 2oz, I’m not sure every one of these upgrades is a
necessity. I can vouch for a few things, though; the screws, turnbuckles and lightweight body are all good upgrades.
The internal gears are good too, as this reduces some rotating weight. I would also highly suggest the laydown
transmission conversion if you’re looking for something that adds shear performance. Finally, if you think you’ve got
the chops (and a groomed track), the Schelle Nova Lockout Set is a fantastic upgrade.
Good luck with your build and I’ll see you on the podium!
