...The next step is to install the motor plate for the transmission block...
I have two choices... there is no right or wrong. It just depends what kind of motor we use...
In the photo above, we can see the transmission block with 3 mounting screws for the motor plate with green spacers...
...I wished the motor plate was thick enough to place locking nuts inside, so I dont have to worry about the motor plate screw threads stripping off over time...

...Now is time to install the slipper clutch...
The slipper clutch is very simple construction. All we need is to mount the spur on to the slipper plate where the slipper pad is applied, a pin into the spur output shaft, 2 washers, a clutch spring and lock nut. That's all...
The clutch spring rate is adjusted to default 2 turns from fully tightened. I will adjust the spring rate later when the whole chassis build is complete...
Here's how it looks like after installation...
There are several benefits of installing the slipper clutch... It helps reduce stress/shock on the transmission gears & drive train when using powerful brushless systems & high torque motors; plus, we get to control driving style, so the tires won't slip off the rock when climbing, etc.
And lastly, is the way the spur gear will react at high torque. The slipper clutch will help reduce spur wobble at high torque situations. Not sure how true that is... I thought wobble happens high speeds. Anyway, I like the idea of a slipper clutch...
There will be more upgrades to the transmission block after this build project (will update in future)...

I am going to install the transmission block on to a skid plate....
For this task, I chose this skid plate. No particular technical reason, I just like the way it looks...
And again, I really wished Axial provided hex screws instead of phillip screws...

After installation, it looks like this...
...and this...
...but then...
...Notice how close the motor plate is located to the edge of the skid plate mounting...
...I need to do something about that for sure... we don't want the spinning motor to bind and hit on that part of the skid plate...

We've got the axles assembled, the linkages are connected to the axles, the transmission block built
... so now...
...it is time to connect the linkages to the side frame...
...in this process, I installed metal radio mounts for both front and rear chassis, in replacement of the plastic mounts. The metal mount not only allows mounting of the radio tray, it also helps strengthen the AX-10 chassis a lot.
and the rear mounting...
... the AX-10 chassis is almost completed... there's still quite a bit of things to do...

...the linkages and suspension are tested for articulation to make sure there is no binding...
...
It's amazing how much articulation there is on the AX-10 right out of the box... 
...I like !!
