These are step by step instructions on how to install our Ion Pro 2S Pack in your MR02. I used the Motul Skyline, but the process is the same for all MR02 based Mini-Zs. The Mini-Z Monster Truck and the Overland install the same way. This will work on any Mini-Z except the F1 and the MR-01.

Small Phillips Screwdriver
Small Flat Screwdriver
Hobby Knife (If you are clumsy, get a parent to do the cutting)
Soldering Iron & Solder
Side Cut Nippers
Mini-Z Ion Pro 2S Pack
Mini-Z MR-02 Motor Wire Upgrade (Optional)

You will find many of the tools used in this tutorial in the Tools & Supplies section.

First you simply need to take off the body and take a good look at how everything goes together so you will be able to reassemble it properly.

Next remove the screws holding the shock and the antenna, as well as, the motor pod. Pay attention to how the little support under the motor goes together. Now remove the top cover plate.

Next remove the screws holding the battery wires to the factory battery tabs.

Carefully pull the main board out of the way.

Using a small flat blade screwdriver, remove the factory battery clips. They require a bit of force, but will slide out without damage if you take your time.

Continue removing the battery clips.

These are the easy ones.

This one is a bit tougher. Take a good look at how it slides in and simply reverse the process.

When you are done you will have a pile of clips like this. Keep them in case you decide to go back. Like you ever would:)

Now that the clips are removed its time to make a decision.

Optional Step:
I prefer to remove the dinky factory power switch because it will cost you power, and power is kind of the point here. The danger is that if you forget to unplug the batteries when you are done, the batteries will be toast in the morning. So think carefully about this one.

Switch removed.

Take a piece of the SuperFlex 18 power wire and tin it as shown.

Solder the end of the SuperFlex 18 across the power switch terminals as shown.

Clip the long end off. Now you have eliminated a big power loss from the system. Just remember to unplug the batteries when you finish running.

Next remove the power wires as shown.

Make a 3/16" hole in the top cover as shown.

Thread the Pro 2S Pack Board Harness through the top cover hole as shown and solder it in place exactly like the factory wires were done. If you get confused, the black wire goes nearest the edge like the photo shows.

Tuck the servo wires back down into the groove along the left hand side, as shown, before replacing the top cover.

The wire fits perfectly and all the seams close if you do it right. If it won't close, you have something wrong.

Next cut two 1/8" holes for the battery straps. You can use a drill or a hobby knife like this one.

You can go ahead and strap the batteries in place now.

The straps go through the 1/8" holes you just made and over the batteries, as shown. Plug it in and test the steering just to be certain you got everything right. Its pretty hard to screw this process up if you follow these steps, but there is a little "dufus" in all of us. Trust me I know, I have had more than my share of brain farts.

Optional Step:
This is also optional, but why would you go to the trouble of a Lithium upgrade and not do it? (This is known as a rhetorical question)

All you need to do is solder the wires, which are provided in the Motor Wire Upgrade, to the factory motor wire tabs. I use a helping hands tool to hold things while I solder them.

This is what they should look like when done.

You will want to snip the plastic tab between the motor wires. This allows you to angle the wires out to miss the shock boom.

If you leave the plastic tab in, it forces the wires to go out straight like this and they will hit the boom and interfere with your suspension.

Now that's more like it. See how they angle out and swing around the suspension components nice and tidy like. Solder the black wire to the top tab and the red to the lower one as shown.

This is a top view showing how the motor wires swing around in a nice arc that allows perfect suspension movement with the SuperFlex 18 wire.

Pat yourself on the back, because now you are done.
