Howdy, howdy, howdy!

It's been a few weeks since I last went crawling. During that time I did some upgrading. Picked up a replacement steering servo, a Cirrus CS704/MG. Huh? What? Basically a hi-torque metal gear servo. It outputs 181oz/in at 4.8v and 195oz/in at 6.0v. ...zzZzZZ... That means...More Power! (insert Home Improvement Tim Taylor grunts) And while getting the servo, I also picked up a new truck body: a Pro-Line Rockstar crawler body (energy drink not included).
I also upgraded to some diff locker kits. The Venom Creeper has front and rear diffs that are unlock-able. When rock crawling, you don't want any wheels just spinning in the air. You go no-where really fast. With the diffs locked, all wheels get the same amount of power all the time. The down side is when you make a turn on a flat-ish surface, you need a lot more room (or simply just make a 100 point U-turn). With unlocking the diffs, you can make a tighter turn, but you loose rock crawling and climbing power. And getting the kits allows me to work on the truck. That's always a plus.

And now for a little show-off shot. If you look at most rock crawler pictures, they usually show off how much articulation there is. And here is mine:

After all the upgrading, I finally went crawling at the in-laws back yard again. Crawling there actually provides two sides of entertainment: 1) I have fun crawling on the rocks, and 2) my nephews are entertained and help out. They like to help it get unstuck, and this last time they even built a rock wall for it to try and knock down.
Here is the rock wall challenge:
And the crawler lost:
Don't worry, Ron, no landscape lights were harmed during this crawler session.

So after the wall, I decided on a real challenge: to attempt to climb to the top of the large rock in the back yard.
Let's try this side:
That didn't work. How about this side:
Oh no! The crawler is in turtle mode:

Well for that day's adventure, the score is crawler 0, backyard 2. Until we meet again, backyard of the in-laws. Mwahahaha!

And here are a few fun pictures. Along with all the other gear installed, I also have a light installed. In the above pictures you can't really tell. It's either turned off or the flash provides too much light. So here is a picture of it:
Another annoying advertisement plug:
the light kit used is an ElectriFly FlyLites kit by Great Planes.

As you may or may not know, I have taken all of the pictures you had seen so far. Now I'm not a camera pro, or even an amateur. I just take pictures. Sometimes I actually get a cool shot, like this one. It looks like a fake photo. Did I really drive on the rocks, or did I just paste in a shot of the truck?
In actuality, it was getting dark out and I used the flash on the camera. I might have even had it set on night mode. Either way, this is a one time cool shot that I most likely will never be able to replicate.

So until next time, have a great crawling adventure out there.

Greetings programs!

This is a little blog about Radio Controlled Rock Crawling. I am an R/C hobbyist, and have just recently broken ground into R/C Rock Crawling. What is it? Just like the name says: Radio Controlled vehicles (namely trucks) crawling over rocks. Slower than a toddler, but faster than a snail. Most R/C classes are more about speed, and getting to the finish line as fast as possible (without crashing). Rock Crawling is more about control and planning (well, that's my take on it anyways), carefully choosing your path over the next boulder so you don't get stuck. In competition, you earn points for mistakes and no-no's (like using reverse), and the winner is the one with the least amount of points.

My recent venture into the crawler world led me to the purchase of a new Rock Crawler kit: the Venom Creeper.
Some assembly required, and all electronics not included. But that is the fun part for me: building the kit and installing the running gear. The build time took me a few nights to complete, but well worth the work (and allowed me to catch up on some TiVo recordings).

Their crawler is available in 2 color trims, and I decided on green. Here it is ready to roll:
The paint job is my doing.
It is inspired from the Cactus Cooler soda cans.


For those that are interested, here is a list of the running gear I currently have installed:
  • Airtronics MX-3S transmitter and receiver
  • Novak/Traxxas EVX Electronic Speed Controller (modified for 1 battery pack)
  • Traxxas 2055 Servo for steering
  • Hi-Energy 3300mAh Ni-MH 7.2v 6-cell battery pack
  • Axial Racing 55T Crawler motor
Not the best for competition, but it gets the job done: crawling over rocks. So far, I have had 2 adventures in crawling. And I like it. Guess what that means? Yup. More Rock Crawling kits to pickup. Just don't tell the wife.

Some crawling at the in-laws up in Utah:

More crawling at the in-laws, but in Las Vegas:

Well, that's all for now. It's my weekend, and I hope to find some more rocks to crawl on.
