The Team Associated RC10 B74.1D Team 1/10 4WD Off-Road Electric Buggy Kit is the buggy to choose for clay and dirt track surfaces with an included center differential with 200,000 CST silicone fluid and an optimized dirt kit setup.

The off-road RC car racing scene has changed over the past few years, with turf and carpet racing becoming more popular and grip levels at an all-time high. The engineers inside Team Associated's Area 51 were quick to answer the 4WD class with the RC10B74 Team Kit, a unique chassis configuration equipped with a long list of features designed to give you the winning edge.

The B74.1D features redesigned, low-profile shock towers with shorter shock shafts and bodies to lower the center of gravity, providing more predictable handling. Also included in both kits are redesigned low roll center (LRC) C and D arm mounts, 66mm CVA bones and axles, and 2.0mm G10 fiberglass chassis brace supports, which all add up to making the B74.1D easier to drive, and easier to push hard on all track surfaces.

Setups and tuning parts are interchangeable between the B74.1 and B74.1D. Both versions come with the speed, durability, and lineage expected of a true champion. Choose the configuration that suits your track and conquer the competition!

Team Associated RC10B74.1D Team 1/10 4WD Off-Road Electric Buggy Kit
Overall, the car is Really good as far as design and performance. Once you get it up and running ( 5 STARS ).
I still haven't broken any parts which is good.
Unfortunately, I have had some issues and 1 failure due to poor quality. I think Associated has let their quality go way down in order to save money.
The hardware that comes with it is literally the worst I have ever used on any RC car ever. They are very shallow and the quality of steel is shit, so they will strip easily. I replaced all them all with titanium from an aftermarket company.
DO NOT USE LOC-TITE ON THE CAR ANYWHERE if you don't replace the hardware first.
When I communicated these issues to Associated, I was first met with the usual lack of acknowledgement and denial by Dick Saxton - eventually they came around; and Amain took care of me as usual.
The front arms will bind at first assembly - the front and rear holes for hinge-pins don't line up perfectly.
You will have to sand down the rear arm shims or they will bind as well. Quickly the plastic will loosen up and these issues will go away.
One of the front CVA joints had a "nipple" inside that I had to file down to get it to assemble.
After a few practice days at the track I noticed a lot of slop and play in the front and rear diff outdrives at the diff. cases- weak diff case or insert plastic ? I will update when I rebuild.
I also had a 5x12x4 bearing fail at the inside rear hub. Replaced with Xray because that's what they had at the track - but they look identical.

It is a GREAT kit, just like anything else made by Team Associated, however, the kit came out of the box with both front axles bent and I had to try to fix them because no one had the parts in stock! Also, the front and rear diffs didn't have enough shims to space it properly. With that being said the diffs make this horrible noise from where they are grinding on the inside of the case. I haven't even been able to run the car at full scale because I've been waiting on parts. VERY NICE KIT, JUST NEEDS SOME TWEAKING!

Team Associated RC10B74.1D Team 1/10 4WD Off-Road Electric Buggy Kit
Build went together very smooth with no issues, manual was easy to read with a revised setup sheet and manual page and the quality is very good. Overall, pretty impressed with the car after the initial battery packs and the kit setup works quite well for most indoor tracks. Haven’t had much run time but the toughness has been tested by some decent crashes and the buggy was unfazed. Very easy to drive and love the ease of diff access and pill adjustment. Well done AE!

Team Associated RC10B74.1D Team 1/10 4WD Off-Road Electric Buggy Kit
The buggy is awesome. A fun build with high quality parts. There's a need to replace any fasteners that require loc-tite with stronger screws because the metal likes to strip over time. This rig Rips with a stock setup. Absolutely no lack of control, steering response, in air accuracy and the suspension is insanely good. I love it
