Axial Yeti is the best RC crawler-it can crawl and run with power

Protected by Copyscape

Axial has a good reputation for making off-road RCs with good performance.  Yeti is a vehicle that gets me into four-link suspension and lets me drive into the world of rock racing.

Main specs of a Yeti:

  1. Front independent suspension and Rear four-link suspension with a solid rear axle
  2. 90mm front shock, 120mm rear shock
  3. AE-3 60A ESC
  4. 3150KV 550 motor
  5. 2.2 /3.0 short course wheels

Overall this chassis is beefy that can take impact if you decide to jump big ramps and the locked rear differential definitely helps the truck in acceleration. As stock, it looks fantastic with licensed stickers and a molded rear roll cage.

For the drivetrain, Axial decide to team up with Castle Creations to develop a supreme motor which can run in any condition. The acceleration on this truck is brutal even with a low gear ratio gearbox as you can change it to a hi-speed gearbox but you can easily achieve 40mph using 3S batteries.

On performance wise, it can compete with the Losi Baja Rey (not the super Baja Rey).  Compare to the Losi, the yeti has a more square shape from the above while the Baja Rey has a more rectangular shape means that will cruise more stable on the loose surfaces.

However, the yeti can turn sharper with a shorter wheelbase and by having a shorter length, the CVD mid-shaft, therefore, is shorter, so less force is needed to turn the wheels.

The Yeti can keep up with a more light-weight Traxxas Slash 4×4, despite it will lose some space during corners, it will gain corner speed really quick to put me back into pace.

Advantages:

  1. Good handling when it is with original parts
  2. Excellent suspension travel
  3. Adjustable Coilover positions
  4. Adjustable rear anti-squat
  5. Scale looks
  6. Excellent grip on replica BFGoodrich KR2 tires
  7. Strong stock servo

Disadvantage:

  1. Only have rear roll cage instead of a full roll cage, a bit lack of protection
  2. Various weak spots on the body shell
  3. Weird pre-load anti-squat link position (links should be 90° to each other)
  4. Bad on high grip surface (vehicle will flip over because locked rear differential)
  5. Lower front A-arm pins will bend at high impact
  6. Stock plastic CVD shaft will bend if using a higher gear ratio

Recommend upgrade parts:

Here are 3 areas worth your attention.

For my own experience, the front doesn’t have enough travel to deal with big jumps and mostly will bottom out, causing the lower front A-arm pins to bend, letting the whole car acting unstable.

Second, it seems like the truck doesn’t like turning into long curve turns so when setting up the suspension, you may want the rebound to be less aggressive to let the body roll.

Third, the stock gear ratio is decent for the setup but if you still want to enjoy hitting a crest at high speed, you can change it into a higher gear ratio.

 

So below shows what I have modded to mine:

  1. Vanquish Products Front suspension extension mount (lifted 10mm)


  1. Gmade XD Piggyback 93mm front shocks with Yokomo #450 shock oil
  2. Stock suspension with Yokomo #350 shock oil
  3. 17T Pinion gear
  4. 68T Spur gear
  5. T-Bone racing Bumper
  6. MIP CVD mid-shaft

After I apply these parts, I found that the vehicle can now handle more like a trophy truck when it hits the ramp, it won’t go nose down which will cause you the lower front A-arm pins. Else, the truck is set up around 47:53 in weight distribution so it will most likely to land on the back wheels first.

In the photo shown above, you can see how I reinforced the weak spot on the shell.  It is the grey square spot in front of the rear wheel arcs. I simply used duck tape to add more layers on the spot.

Rebuilding it:

I had to rebuild my Yeti after two years of ownership and I found the chassis so well design that it hasn’t seriously bent. The four-link suspension has an excellent design although I keep hitting them with big jumps and rough terrain. To say in a simple way, the overall durability of the chassis is supreme and electronics last forever that I’m still using the same electronics on my Axial EXO Terra.

However, nothing is perfect, the screws seem to rust out even a lubricate them constantly but they still manage to rust out. This is the pain working on this vehicle. Whatsmore, the structure of the chassis is a bit complicated for a beginner to start with since parts can be on top of each other, making the disassembly process more confusing.

Summary:

Axial Yeti is a truck that I appreciate to despite it may not be the best on the market, Axial has the passion to build a cheap as possible chassis for those who love trophy trucks like me and it turns out to be one of my favourite offroad chassis of all time. The performance out of the box and the capability of the chassis can surprise you every time once it’s ready to rock ’n roll. Although this may not be the best choice for a beginner, it lets you learn the basics of an off-road truck which you will find the skills comes in handy along the experience you gain from that chassis.

Its like you learn my thoughts! You seem to know so much about this, such as you wrote the ebook in it
or something. I feel that you just could do with a
few percent to drive the message home a little bit,
however instead of that, that is wonderful blog.

An excellent read. I will certainly be back.
