Installed the T-Bone Racing skid plate. It comes nicely packaged


And looks even better on the truck.


The material itself is great and itís easy to install. I like that it protects the aluminum skid plate - odd, but I have this nagging compulsion for the aluminum skid to look new forever, Lol. Maybe it also keeps some dirt out of the motor compartment, or at least the seam around the motor plate. Who knows. Only downsides are more screws to remove if we do pull the motor - although the soldered connections between the motor and ESC would make this hard anyway - and the slight lip at the back end reduces the opening for the battery box slightly. Not a big deal for me since my batteries fit fine ...

Next is a possibly unnecessary upgrade, but I like it regardless, so why not? Plus Iíve read about the stock part breaking in at least one thread and you can never be too cautious with proactive upgrades, right? Turns out I also like the endless wrenching.

And thus we have the Hot Racing front shock brace!


And Ka-Blamo! Installed on the truck


You may have noticed it was already installed yesterday, but whatís a few hours between friends, :thumbsup:! You can see I still need to swap the shock springs. Thatís coming up next.

The shock brace itself is nicely made and easy to install. The slender portion near the top where it plugs into the shock towers is a little different; seems like it could be one width all the way to the end. But itís a minor gripe and likely doesnít make any difference anyway. Iím hoping this is the last time I pull the shock towers, but probably not since Iím amassing the black parts for the cage and will (sadly?) need to take most of the top apart to install it, !

Maiden voyage on 3S today and OMG, this thing is a beast! Barely any torque twist; handles really well, especially at speed; corners nicely; fantastic torque off the line; beautiful steering response; very little body roll. Itís definitely my fastest RC, even compared to my Nitro Slash. Well into the stupid fast regime, Lol! I did roll it a couple times, but I knew I was pushing too hard on the speed / cornering radius. For the most part, itís happy to do reasonably tight corners at speed, much faster than any of my other rigs.

I only got to full throttle once and then only for a few seconds. Fairly certain the front tires reared up and ballooned. Oh, the glorious beauty! The HW motor just screams! Definitely need a long straightaway to run at full speed. A city block is not enough, Lol! I might even consider getting some 2S batteries, which would be a first for me.

Only carnage was the paint on the top, which is already starting to chip. At least itís an easy part to re-make and I have more Lexan on hand so no troubles there. Bummer to re-learn that Tamiya TS paint is not for Lexan, !

Absolutely fantastic and more than I was expecting. The RR is a sweet rig and perfect for this kind of high speed bashing. So excited I was able to get one of the kits and that itís turned out like this!

Finally found the time to tune the springs on the front PowerStrokes. Hereís the stock setup - the A-arms are almost horizontal and the primary springs are fully compressed - not the best setup!


Thanks again to mass-hole for pointing this out in post 62. Check out his build thread here: Mass-holes Rock Rey Build Thread

I started with the Proline spring assortment kit


I tried two setups: red primary and secondary and red primaries + the stock yellow secondaries. The suspension was a too bouncy with the red springs in both positions. Could probably improve this with thicker oil? Not sure and Iíll need to get some to give it a try. For now, Iím going with red primaries and stock yellow secondaries. I also adjusted the preload. I wanted to try linger rod ends, but then realized that all of my stock is for larger OD rods. Awesome preparation, Lol!

Hereís how it looks now. Canít wait to give it a try!

Reds are the only way i can get the primary to not be fully compressed just sitting. It takes too much preload of the springs for the lighter primaries to be able to deal with it.

Also, The lighter the secondary spring you run, the more travel you get from the primary since the secondary will take more of the compression.

This came to me when I was tuning the Gmade dual-stage shocks on my Bomber. I "inverted" the progressivity of the shocks so the higher spring rate activated as more of a bump stop.

Nice, thank you! Itís interesting how long it takes for all of this to be intuitive, Lol!

Nice idea, would not have occurred to me!

Itís hard to believe how much has happened since I first built the Rock Rey. Iíve been sitting on a few upgrades and finally found the time to put them on the truck.

The first one is more of a fix than an upgrade. Sadly the motor wires I installed in the first round were too short, which meant they were under constant stress from the interior / drivers. One of the connections got flakey, the motor would randomly cut out, and I thought the motor / ESC had died in some terrible way. But no, just builder incompetence. You can probably see this problem looming on the horizon in the build pictures I posted at the time. Iíd look back, but the shame is too much for me.

So hereís the first upgrade. Boom, suitably long motor wires! Donít worry about the sensor wire, it lays down nicely when the interior is installed. Iíll add some wire ties. Drives like new. Huge performance gain, lol!

The second update is more legit in the sense that itís actually an update - Hot Racing aluminum and carbon fiber rear shock towers!
https://www.rpphobby.com/product_p/hotlrr30g06.htm

I wanted something stronger than the stock plastic parts and Iíve had good luck with other Hot Racing upgrades for the Rock Rey. The shock towers are a little pricey, but I got them on sale.

I should have taken an un-packaging photo, but major fail, I forgot to do it. So here they are installed on the truck. Itís the first time Iíve had carbon fiber anything. Theyíre sweet parts and look awesome installed. Canít wait to see how they perform!

I have those same towers and they have held up well to my bad driving lol. I need to get my Rock Rey out in the dirt again, as I've been more into crawlers the past few months. I break less stuff that way lol.

Great to hear! Itís all about having fun, right? Crawlers are awesome and I agree itís a great way to reduce breakage. The Rock Rey is a sweet truck - shocking at full speed, lol!
