Review: Team Yokomo YZ-4 by Chris Sturdy

Who better to review the new Team Yokomo 4wd, 1:10 buggy, than one of the people who steers them best, Chris Sturdy.

Yokomo YZ-4 Review!!!


Quality…One word that describes this buggy, The quality of this kit in my honest opinion is second to none.

The Build

The build was perfect, everything went together so nicely. The fit and finish is perfect and feels amazing. As you can tell this buggy is a whole lot different to the Bmax4III. I’ll point out some of the major changes. Lets start with the biggest change and one that a lot of people seem to think makes this buggy worse than the Bmax4III….Yes the belts. But it really isn’t what you think. The way Yokomo have designed the drive train it still has great acceleration and does not feel at all like there is a slight delay with the belts at all. On track the Drive line feels amazing, super smooth through the power range while without loosing any acceleration. The belts are very heavy duty as well and nothing like what i have used before.

Next is the steering assembly. Very different to the Bmax4III, similar design to the YZ-2, In fact it uses the same Bell crank parts. This eliminate the servo saver which on the Bmax4III had a habit of coming loose at the wrong time. This assembly also has 4 extra bearings to its predecessor when using the alloy assembly on the YZ-4. The kit comes with plastic parts (insert Oh No its Plastic jokes here) that are insanely tough and feel very rigid. The same can be said about the plastic suspension mount parts for the rear arms and the plastic shock towers, they feel very ridgid and by no means feel cheap.  Keep in mind how much it costs to make a mould to produce plastic parts before you go saying that plastic parts are cheap especially this high quality. I opted for the alloy suspension mounts as that’s what Yokomo sent me otherwise i would have just used all the plastic parts that came in the kit. One more addition to this buggy is the use of a front clicker pulley. I recommend this for stock as it works similar to a one-way diff in the front of a TC car. The clicker takes drive off the front of the car entering corners allowing the brakes to pivot the car more like a 2wd buggy. For modified I suggest taking the spring out all together.

One negative with this buggy is that due to the belt drive train, is it is harder to remove the gearboxes compared the the BMAX4III but by no means is it difficult, its just abit more work. There is so much more i I could write about new additions to the buggy but would make this article A LOT longer.

Here is a full list of all the Option parts that i recommend getting for adjustability:

  • Z2-300RF – Rear suspension mount (Front side)
  • Z4-300SRR – Rear suspension mount (Back side, for S4 arm)
  • Z4-300FU – Aluminum Front Upper Arm Mount (L / R)
  • Z4-412 – Anti-roll bar set x2

The Drive

The drive was honestly surprising, I didn’t really know what to expect but was honestly surprised with how easy the buggy was to drive. So much easier to turn corners than the Bmax4III and consistent from entry to exit. The buggy hugged the apex’s on low speed corners and didnt slide when I got on the power too early. We actually spent most of the day trying to get rid of a bit of the rear grip the buggy had. A the end of the day we took the wheels off the YZ-4 and put them straight on the Bmax4III and ran the Bmax4III once.  After spending all day driving the YZ-4 I realised how much more edgy the Bmax4III was. I have spent alot of time getting the Bmax4III as good as it was for that track and after 3.5 Hrs testing the YZ-4, the YZ-4 was already slightly faster but so much more consistent and we have only scratched the surface with the setup if even that! All up I think if you thought the YZ-4 wasn’t going to work on dirt all I have to say is…THINK AGAIN!

I would also like to Thank Team Yokomo for their continued support, I’m honoured to be able to represent them!

New Team Xray XB2

Details have finally landed for the new XB2 from Xray, and, well it is not often that I would say it, but it certainly sets a new benchmark.  With a Dirt and Carpet car available depending on the conditions you race in and which options that will provide for. With every option in the book from mid and rear motor, and even lay down gearbox and ball and gear diff included, there is hardly an area of design that you may feel the need to change, I dare say none at all.


Now I have not seen any information on pricing, but being a Luxury RC company, it isn’t going to be cheap, but you are getting the best without a doubt.  I won’t go into a lot of detail, because the Xray presentation does an excellent job of it so i’ll simply point you in their direction!

Which Crawler to Buy, 2015 Edition!

Ok, i’ve done a couple of overviews of what is available on the market in regards to vehicles in particular categories or classes, but today I thought Crawlers ought to be the topic of discussion.  Now i’m far from an expert myself as I’ve rarely driven a crawler, never owned one and am hoping to be in the market for one myself soon.

However I saw a great video doing a run through of 11 Trail Trucks (as opposed to outright Rock crawlers with no scale resembelence to real vehicles) by DJ Medic at the RC Sparks Studio and thought that it was as close to a what to buy article as anything I can whip up from behind the keyboard, supported by the fact these are all his cars that he has drive, and can comment with authority on each vehicle.  It’s a 17 minute long video, but worth a watch if you are interested in getting into crawlers.

Traxxas X-Maxx – The Lowdown

Ok, the Traxxas X-Maxx is the new player on the block, and I thought it was a direct replacement for the somewhat senior citizen the E-Maxx, that was until I looked at the dimensions and realised that the X-Maxx was truly gargantuan in it’s size! I mean it dwarfs the stampede in the press photos (don’t mistake it for a E-Maxx, that’s a different photo, also included below).


So what of the features that it is touting?

  • Big and fast, check!
  • Traxxas Stability Management, you wouldn’t want to loose control and run into your mates, or a nearby stranger, a broken leg at speed would be a very real possibility!
  • Body Pin free body mounting system, a big tick, but the large physical size makes this easier to implement, but harder to fit different bodies.
  • No gear mesh manual adjustment, just choose the right slot and go.  Mmm, great idea for noobs, but i’m not sold on the concept on the whole, so that;s a split decision for me.
  • Modular Chassis for strength (and easy maintenance) gets a big tick from me, and I can see this spawning some other models easily too.  2wd Baja buggy for example to counter the HPI Baja 5B perhaps?
  • Clean sheet design, about time!  the last one from Traxxas in off road was the Slash if I recall.
  • Self-Righting system – i’m not sold on this, in the video I have seen it seems to work ok, but i’m not sure what penalty the drivetrain pays for the way it accelerates and brakes. This video from RC Car Action gives the car a good once over, and a demo of the self-righting system at the end
