Looks plenty beefy

May be kinda hard to drive at speed with the 4w steer ?

Yea. I tend to over do it on bracing.
My MIG welding needs some refining too. I'm gettin' there.

These axles came off my wraith Monster Truck. It can work you just have to slow down a touch to whip it around. I doubt it will get used much in the race. But I am pretty quick to hit that rear steer button and whip it around in a tight corner.

It is looking pretty good so far! I love those rims! Any info on where to pick some up?

Thanks. It's nothing fancy and I am just building it to drive the heck out of it in a few weekends.

Those are Eritex Rockers. Discontinued and that dude is long gone.

Got the front end boxed in and mounts for hood and roof.

Thanks. I am no fabricator by any means. Just looking forward to getting this going and having some fun.

Only thing I am lacking is a longer transmission output and swapping out one of the diffs for a locker.

i may hve to get one of those dinky servo mounts too. ive seen them on a couple rigs. really starting to grow on me. ive been called a fabricator at work plenty of times. i always disagree. i can whip somethin up if i have to. thats about it.

The servo mounts are great. Just note there is a front and rear version. Only thing that I don't like is the upper link mount holes are like 4mm size and the 3mm screw/nut can come loose.

I drove this for 2 minutes in the rain right at dark. whoa handles good, tons of power and jumps flat. Might try for a short video soon just need to finish up the side panel mounts and figure out something for the rear.

Thanks. Ran it today and pulled a 2nd place finish in the Wraith class Terra-X

Added the Dinky R/C fuel cell yesterday.

Won Carter Fab Wraith panel set and a Crawler Innovations Wraith Battery Tray. Thanks Clay and Eddie

Spun the rear locker on one side with a half a lap to go. and then busted a revo rod end jumping off the skate ramp afterwards.

4WS came in quite handy for the Terra-X race. I forgot to set my ESC to crawler mode before the race.

Probably a video coming in the near future.

What is the RTR weight?

Looks like you guys had a blast

[dieselmudder]

[TekmoCrawl]

Terra-X racing is a blast. Race was about 5-6 minutes long.

Truck is just under 8lbs RTR. Using a 3300mah 3S lipo

Simple rules. Try to keep off the track (rope staked to ground) and marshal ypur own truck. If you get bound up with another truck pull yours off and place it just behind or ahead of the other truck.

Thanks. Video posted in this thread.

Check out my Twin Hammer's tread for that class video.

[TekmoCrawl]

Ahh, now I see on my pc. The video wasn't popping up on my phone.
Looks like radical fun. A little more adrenaline rushing I imagine.
I (or someoene) needs to set this up in my area!
:Awsome:

[dieselmudder]

do you guys set up a transponder system to determine winner? is it won by first to cross the finish line after X number of laps, or most laps in the alotted time?

[ROLANDROCKSHOP]

land rush start..
5 laps or how ever long or short you want the race..
1st to cross finish wins..

if you roll over,you can flip yourself over,but if someone is directly behind you,you must place your rig behind them..

example...im flipped over and shane and ross are right behind me going thru a bottleneck obstacle..id have to repo behind ross.

if your vehicle goes out of bounds you must re-enter where you went out.
out of bounds is all 4 wheels.

dont stand on track..if you have to cross it do so quickly



And above all else Have fun!
