Default Not So New Bright Rock Crawler (red rubi-con)

Allright, Like many before me, good enough is never good enough. and with this toy grade stuff, cutting and glueing is about as much fun as driving these things! So, Here's some picks of my modifications.
Naturally I started with the suspension. the battery hadn't finished it's first cycle before I had this thing torn to pieces.

this was my progression through suspension pins as I found longer wood screws from various hardware stores.

Default RE: Not So New Bright Rock Crawler (red rubi-con)



The first switch was the springs.Stock ones were too firm, or too long. I havea new bright 1/10 mud slinger hummer that had a set of springs that it really doesn't use anyways. Thats getting a 4 wheel leaf spring conversion.....but thats a topic for another time.

The springs off of this were perfect length and weight for the crawler.I had got it up to almost 4inches of flex, or one tire 4inches off the ground while the other 3 tires still firmly planted, but got stuck at the "slop" issue.

Thats when I found these forums, and got the idea for the limiting strap. (Thanks guys)
I saw pics and threads for yellow crawler, silver scorpion, and several other abominations, thats when I realized I wasn't alone.
Many more ideas came spuing forth.

I found longer wood screws,and with limiting straps installed, found the need to start removing plastic from the chassis, AS WELL as the fenders.

I lowered the body as much as possible WITHOUT removing the floor of the Jeep just to keep some of the scale effect.</p>

Almost all other Modders changed the location of the shock mounts on these. I experimented with this, and found that it didn't gain me much. So, I kept the stock locations and added a washer to the spring to keep it centered.

I tried fabricating a 4-bar-link system on to the stock chassis to combat the lengthening wheelbase during suspension travel. That idea failled miserably. The chassis and battery compartment are much too long. the links would need to conect to the center of the battery cover.

I did a custom cut to the tire treads. I haven't seen any one else use this pattern yet, But I am very happy with the results. Much softer and much more bite!

I'm still trying to improve torque.
I read on one of texx's threads that a 280 size motor would work with the stock electronics. So, without adequate research, I went and bought 2 hobby grade Losi 280 motors. I did a water break in, and then hooked one up to the rear axle wires for a test fire. It was drawing WAY too many amps. It ran for 30sec, then I lost forward on that axle. I still had reverse, so I disconnected it before I did any more damage.

Fried electronics suck!

My friend thinks he can fix it. I'm patiently waiting. But if anyone else has stock electronics to part with, Please let me know.

I'm continueing my build. I found an old Tyco mutator in a thrift store for a buck. It had 2 identical motors that look to be about 280's. Better yet, both came with brass 8-tooth pinions. The Tyco truck was a 9.6v so I am installing them without worry.

This is the resulting monster. Waiting for the paint to dry so I can re-assemble. Then I need those new electronics so I can take her for a torture test.

Haven't picked a name yet either. Could be Not-so-bright 4x4 or something like Red Rubi.......con. I dunno.

Nice paint job, check out my pictures for my 4 link setup. i didn't cut too much of the chassis to loose much, but i cracked the chassis, so i super glued the chassis back together and reinforced the behind inside the chassis to strengthen the wall. works well now!

Here is a link to the 280 motors, if i have extra electronics, i will send them to you if you want them, just pay shipping for it, i bought some spare parts off somebody for real cheap! we shall see!

<a href="http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_232005_-1">http://www.jameco.com/webapp/wcs/sto...0001_232005_-1

</a>I have been doing a lot of work today and yesterday making scale bungee cords for my crawler. and had to fabricate a waterweld made cv ball joint! broke it for the third time again

here is a link to a more detailed and more mods i've done to my NB

Thanks Spiike. Yeah, definitly let me know what you get in that box o parts. and if there is another board in it. even if it's not working, maybe the part I need still does.

Your builds looking good. I like the mini bungees. I might have to steal that Idea from you.

It's driving me nuts not driving this thing. if its not running in a week, I might be forced into going hobby grade. not exactly what I had in mind on this project.

Default RE: Not So New Bright Rock Crawler (red rubi-con)

i know how you feel, i got a mini board track outside that i play on with my truck, and snow mountains from when i shovelled the snow. I'm planning on getting a SCX10 and seeing if i could put my jeep rubicon on that body, I kinda think i might not be able to due to the fact that it is shorter wheelbase, so we shall see! if i do end up taking the body off this NB jeep chassis, make an aluminum chassis and build the axles into a aluminum tuber. I'm sure the box of parts are at customs, so should be about a week or so before i find out about parts

Not really anything new, except for getting those bigger motors in with the 8t pinions. waiting to test em out.

I've been playing with THIS thing for a couple days now. It's been filling my need for crawling and tinkering.
I did the 9.6v mod, this things a monster. TOO much fun.

The Red Rubi Is Alive Again!

Got another jeep for spare parts, and robbed the electronics out of it. So, I'm still classed as "stock". Here are some pics of the new motors borrowed from a Tyco Mutator. these are a bit stronger, and they also came with brass 8tooth pinions.</p>

My Jeep YJ Steering system!

I modified a servo that came off of a radioshack "intruder". Its a 4 gear instead of the stock 3 gear servo. It turns slower and stronger, but it also doesn't return to center. you can turn until the wheels are pointed where you want them, and then it just "locks" them there until you tell them to turn somewhere else. Kind of like a real jeep YJ does if you've ever had the pleasure of driving one.

This also means your drive motors aren't fighting your servo for battery power in those tricky obstacles. turn first, then drive.

by the way. the drag link rod is just a piece of coat hanger.

So I bought a pair of tires.

I TRIED to keep this thing 100% toy-grade or home-made, but you just can't beat that uber soft rubber.
A pair of Proline Chisel 2.2s fit on the stock rims nicely. I figured, clodstall isn't a problem if your front tires get traction! These are working great. I've ordered another pair for the back from lhs.

I like your crawler and your Proline Chisel 2.2s ..

They are certainly better than the stock tires newbright.

Keep up the good work .

NICE, i like, i like a lot. i tried going to my lhs to check out tires for my truck, and was to no avail, when i lined up the rims to tires to see if they fit, they look way too small or way too big. even the 2.2, how well did they fit on your truck?

Thanks Texx. I'm glad to know that "the godfather" is watching.

Hey Spiike. I just lucked out with these tires. they only had the 1 pair, but I got to try them on the rims before I bought em. They fit great.
I paid$26.99. The model # was 1149-14 and they came with a memory foam insert. It said 2.2 on the label, but it actually says 2.30 x 5.40 on the sidewalls. I saw in some prolinecatalogue the 2.2 "hammer". They looked just like these but with more sidewall tread. couldn't find an order # though.

I was thinking of getting a 1/6th scale ambulance that would fit on my NB modded chassis, and do full up LEDs on it flashing lights and a siren, this totally gives me more influence to make one!!! thats ****ing awesome!

The Jackalope .. Cool video.

But, always remember that a body lowered as much as possible is better for the stability of the crawler.

That of the video (the body) is too high.

I lowered my body NEWBRIGHT as much as possible, and the result is very good.

The one reason I did not lower my Jeep was because I did not want to damage the fenders, if i'm able to put it on a scx10 chassis, I would like to turn my jeep into a full out scale build, if I ever get money later on this year, maybe I buy another NB jeep and cut fenders off and lower like the yellow crawler!
