Used Versachem Brake Caliper Grease to grease the gears.

Also added the GR01 Aluminum slipper plate (GM30073).

Temporarily using a SkyRC Ares Pro 540 Competition 8.5T (4100kv) brushless motor for now. If I use this, I'll be using the Castle Mamba Monster X Esc.

If I go the brushed route, I'll probably use the Hobbywing 1080 Esc + Maybe the Traxxas Titan 21T.

Steps 19-27: Transmission

Nice looking so far. Those gears second photo look so weak. I've never been a fan of powered metal.

So far some people have put some decent power through this truck without any issue, so hopefully that stays the case.

Step 47: Steering Servo

I skipped this step earlier, because I'm using the Savox SC-1283SG Servo.
The kit comes with pre-molded servo spacers that encase the servo ears. They are pre-molded to fit most servos that use thinner plastic servo ears.
The Savox 1283 is metal cased, and has thicker servo ears so the pre-molded servo spacer didn't fit.

What I ended up doing was to use Yeah Racing M3 3mm spacers to space the servo up.

Steps 61-68: Shocks

I really need to get some more specific tools to do some of these build steps like the shocks. I'm sure I can do a much better job, but for now I'll keep winging it and improvising with the tools I have.



Applying some Noleen grease (found on eBay) (thanks Jato!)








Bought the upgraded metal rear shock brace for the GOM

Steps 69-74: Steering & Panhard Links/Rods

So, I did run into a snag here. The panhard axle mount that the panhard rod attaches to on the axle uses a countersunk screw to secure it into place. The "eye" of that mount for that countersunk screw isn't very sturdy.

Well... like someone from another forum that did the same thing that I didn't really remember until I did it myself.... I overtightened it by hand and "split" goes the eye of the panhard mount. Grrrr .

It will hold for now as the other half of the eye is not broken.

Anyway, I ordered the sprue that contains that particular part for now, while I wait for the upgrade metal part to show in stock at vendors. The panhard axle mount metal upgrade is one part that I WILL BE DOING.
