Axial Yeti 1/10 King of the Hammer Build with Metal Concept A Arm and more...

Finally Got my some upgrades put together. Upgrades including, The Metal Concept Gull Wing A-Arm, aluminum gear box from local RC hobby store, Vanquish Front Axle with SSD Widen Axle set up for the REAR (Yes, only the front axle can make the wider setup). So many upgrades have done to the Yeti. Want it to look as "King of the Hammer" as much as possible.

Had the Mamba Monster 2 Mounted back to the original ESC area (I mounted it at the oil tank for bettering air circulation) . Had some of the esc plastic plate trimmed to allow the steering servo mount move freely. As the steering arm is a bit longer than the original one. The complete aluminum gear box fit perfectly, however the 2 speed transmission "hole" is sealed in the aluminum gear box, my original plan is to include the 2-speed within it. Anyway I may consider to do if I give up the aluminum gear box.

The reason I upgrade the electronics to Mamba Monster 2 with 2650kv motor is to run the Yeti with 4s. But 4s is too much power to the drive train, and it will eat up the front and rear diff bevel gear very quickly. I'm using the Hot Racing Spiral Diff Gear and I found it has no dramatics improvement to handle more power. So as soon as there are no better bevel gear on the market, I will stick with 3s.

In order to make the Axial Yeti wider for better scale look and stability, I keep the SSD Axle Wider Kit and combine it with Vanquish Currie Front Axle for realistic scale look. If you are a Yeti owner, you may know that Yeti has the wider front than the rear, so the rear wheels are equipped with a widener wheel hubs.

The SSD Axle Wider Kit allows the Yeti has a equal front and rear.

If you want to combine the SDD and Vanquish Axle as well, you CANNOT purchase any axle has the pumpkin in the middle, as you need an axle that fit the SSD wider version shafts. Any vanquish front axle for Bomber and Wraith should compatible with SSD wider shaft, as Axial only has ONE version plastic axle for bomb and wraith. You need to look for vanquish axle which has the same design with the Axial original one.

On the other hand, as I put the front axle to the rear, you may notice now the pumpkin is on the right side of the rig (instead of left), and the diff set up is REVERSED. So you need to also reversed the diff set up at the front in doing so to keep both the front and rears wheels turn correctly.

As below, the Metal Concept Gull Wing looks amazing at the Axial Yeti. It looks much beefier and thicker than the original plastic, RPM or other aluminum a-arm on the market.

The next thing I wanna do is to make a DIY LED light bar beneath the roof. Yes I would like to have them inside rigs. LED Light bars on the market are expensive and bulky.

Axial Exo Baja 1000 build

Getting tired of the existing Axial Exo looks. Happened to find some Baja 1000 Buggy photos on the Internet and I love those looks. Now I'm starting to collect materials to build a Baja 1000 Buggy from my Axial Exo frame and chassis.

Savage Electric final build

After a short period of nitro, I realised I don't have the talent of tuning nitro engine and decided to go electric (again), except I think gas require less tuning and easier to maintain, so I keep my Baja gas powered.

I originally purchased Kershaw design V3 conversion kit. You can keep the 3 speed transmission make it a 3 speed electric savage. It was fun. Then I decided to purchase Alza Racing conversion kit along with its TVP chassis. As I read in forum, many have good feedback about the center diff set up. I like too as I like easy maintenance.

There is a long period of the time where HPI's savage battery tray is out of stock. It happened Rovan sell clone savage (in China), and they sell battery tray, which is perfect fit for Alza racing TVP chassis hole (I tried to drill hole to the original 5.9 XL chassis, but too much hole and I decided to upgrade it).

I will list what I did to the savage later.

36cc 1/5 Baja Super Budget build

Got a 36cc Rovan 1/5 Baja from Taobao for around US400, including 36CC engine, 3 speed tranmission, front disk brake. Soon I figured the traditional HPI steering set up is pretty weak for turning.  Then I give up the disk brake system (less burden to the servo) and put the symmetric steering to it. HUGE improvement for the Baja....

Driving test coming soon.

My New Axial Yet 1/10 King of the Hammer Build

Been a long time since the last time I updated my Axial Yeti King of the Hammer Build.

More build detail coming soon...

Best and cheapest lipo battery recommended for your Axial Yeti and Exo (4s only!!)

After I planned to upgrade my Axial Yeti 1/10 (to goes 4s or beyond), one of the first things I look at is the battery case. Apart from limited motor space, there is actually also limited battery space as well. So I have to find battery which can fit my Axial Yeti first.

The Turnigy 5000mAh 4S1P 14.8v 20C Hardcase Pack from Hobbyking fit both of my Yeti and Exo perfectly. For the Yeti, you simply just need to take out the roll-cage holder and battery will fit straight in. For the brushless system, you may need to look for Tekin Pro 4 HD 4S - 1850kV if you have budget. The motor will fit perfectly.

There is a few reasons that I go for 4s for both of my Axial Yeti and Exo. One reason is that I found 4s lipo battery is relatively cheap (for more power). Each 4s battery is around US25. So I just turned down the pinion/spur setting abit, adding a cooling fan and I will lot of fun with massive power of 4s lipo.

For those who planned to run on 4s, do not use motor which is higher than 3000kV. As the RPM would be very high and your motor will overheated. Short course combo is ideal for Axial Yeti, but most SCT esc is 120A (not sure about those from Castle Creations and Tekins). If you want to run the Axial Yeti like a truggy like me. I prefer Monster Mamba 2 (waterproof and sensorless) or Tekin RX8 Gen 2(sensored) or 150A esc to give more robust power for the vehicle.

Set up of my Axial Exo Terra Buggy on 4s!

After getting back to RC hobby months ago, Axial Exo Terra Buggy is one of the RC that really catch my attention. The look of it is sick and the general weight balance, and steering and control just so nice (thanks to the review of JANG, founder of the URC forum). However, the Axial Exo Terra Buggy went out of stock everywhere and I soon figured that Axial has discontinued both the KIT and RTR version.

Luckily enough, I found someone who was selling a used (yet 95% new) Axial Exo kit with carbon fiber, aluminum and RPM A-Arms upgrades. He sold for around US250 without shipping through Buyee. Although the service fees and postal cost is not enough (I forgot the exact amount), I like the Axial Exo and it is a discontinued RC with great condition.

As my Axial Yeti will be using sensorless system. I really want my Exo goes sensored. On the hand, I figured that the Exo and Yeti both has the similar battery room (after mods), so I decided to use 4s lipo on both of them. The reason I use 4s? I just want more power for my RC and 4s lipo is cheap :D

For the brushless system, I don't have the budget for the Tekin Pro 4 HD 4S - 1850kV. Instead, I went for the Hobbywing XERUN-SCT-PRO 1/10 Combo 3400kV. I bought from Asiatees and this brushless and sensored system is actually really nice. It is really responsive and there is no clogging at all. I will a bit too much on 4s, so I have to add a double fan cooling fan from Yeah Racing.

I will post more photos and diff oil, pinion/spur set up later.
