Default NB 1:10 Rockcrawler - stock

Hi all. First post here.

Ijust got a stock NB1:10 Jeep rockcrawler. Its been sitting for a while and there's flat spots in the wheels (Isee WD-40 will soften them so will try to fix that). It has the battery, but no charger, nor remote. Ilove the mods here and am looking forward to mod'ing mine as well.

Anyone have a remote and/or charger? Or know where Ican get them?

Thanks!

@SunFireFoot, I've actually ordered a new N/Brockcrawler for the transmitter and charger... and spare parts.

All, I'm almost done with a 4-link suspension for the rear of my NBJeep. Should have the shocks mounted this evening. Ihaven't even received the new crawler in the mail yet, but am almost done with the rear suspension mod.

Iwil be adding a 4-link to the front as well. The steering is on the back side of the front axle soIwill flip it (re-wire) so the steering linkage is in front and not in the way of the 4-link.

Imay be able to start removing the factory stickers from the body too.

Couple questions...
 What 280 motors can I use in my NB 1/10 scale Jeep crawler... without frying the electronics?
 (and if you know where I can find them I would appreciate that little bit of info too)

 What's the benefit of removing the return to center springs

Hello ... kasteer.

Good job on this NB 1 / 10.

You will find the 280 in stores HOBBY / GRADE .. and can be on EBAY.



Their price is reasonable.

The forum is idling in this time and I rarely have a look here.

The return spring can be removed. The advantage is that the steering motor, will be less difficult to work and conduct will be easier on the rock.



Will conduct quite well. You will get him back in the center with the controller.

Do not forget that these NB are made ​​for climbing, not for the race ... so it is slow.

And for this reason YELLOW CRAWLER, has a 4 th hear.

After............................................. .................................................. ....Before...

Keep up the good work.

steering return spring = removed.

Last night Iremoved stock steering setup and installed threaded rod system in its place.

Still waiting on the new NBcrawler so Ican test the electronics.

Planned stages for this build:
1- suspension replacement, springs, lower...
2- motor replacement
3- radio replacement

texx, you mean a 280 motor like this? Description says up to 6v, but my NBis 9.6v....
http://www3.towerhobbies.com/cgi-bin...&I=LXSR95&P=ML

What about this one...
http://www3.towerhobbies.com/cgi-bin...?&I=LXWK50&P=7

Graupner motors are good motors, but their price is quite high.

I think your second choice would be good .. I am not so documented on the issue of moteurs. I found mine in a war-tank radio shack I think ..
They were 280 and it works very well ..

All 280 that accepts 9.6 volts should do the job.

With the 4 th gear, you do not have to change engines .. the crawler will be very effective all the same. The speed is slow and the crawler is very strong.

Look on the forum, many have installed different engines.

Ithink I'd like to swap the motor first and see how that does.. if needed, Iwill do the 4th gear. Not too keen on the 4th gear since it's open and dirt could get inside the gears.

In the forum, Isaw people re-using motors they had. Ididn't see too much about specific purchased ones... except to avoid the Losi motors.
Just found a 10v-12v train motor on ebay for 7 bucks... interesting...

Yes, the dirt can penetrate, but I covered the engine and gears with a piece of black cloth ... and I stick that I could remove if repairs were needed.

For a crawler climbing requires that its speed is very low and the engine does not force the endroirs difficult.

In other words, all four tires must turn if we place the nose of the crawler on the wall .. and as long as the batteries are working.

So, the installation of the 4 th gears on the NB 1 / 10 is almost necessary.

I agree wiht you about low speed.  I have a 1:1 scale Jeep that I take off road almost regularly.  I am looking at the new motor as being more powerful and I hope to have more torque.  Depending on how that performs will determine if I add the 4th gear.  I would like to avoid it if possible, but will do it if necessary... I guess I need to see how the motor performs with my own eyes (I'm hard headed like that ).  But I hear you... 4th gear is pretty much necessary to cut the speed down and increase torque.

Is the stock motor in the 1/10 scale good enough to keep and only do the 4th gear?



With an ESC... wouldn't a better motor be better, when the speed can be controlled?

YELLOW-CRAWLER has its stock engine.

I installed the 280 ... but I found the speed too fast on the rock.

I replaced the stock engine and all is well now.

Without the 4 th gear, the 280 helps a little for strength but the crawler runs a little faster.

(((( To install the 4 th gear, you should consider all the thread related to it. Many have succeeded. ))))

Sounds great!  I thought the stock motor would be too weak... but if Yellow Crawler has the stock... I'm convinced to leave it and do the 4th gear.

Now to find the right gear (x2)...

Thanks!

P.S. I've not been very successful fixing the flat area on the stock tires... looks like I'm going to have to pay for new rubber, or use the tires from the new NB crawler...http://www.ebay.com/itm/190596596406...84.m1439.l2649
Not a Jeep, but good parts...  Not sure I like the tires/rims tho....

I think I worked four tires (cut (thins) with an exacto) YELLOW-CRAWLER in reserve.





I search in my locker and I give you news tonight or tomorrow.

texx,
I'm trying to figure out gear ratios...
I have a 10 t pinion... next gear is 42 and 16 teeth, another 42 and 16 tooth, and finally a 42 tooth...  I calculate about 29:1 ratio.  If I replace 10 tooth pinion with 8 I get 36:1... and if I add to that, a 34 and 10 tooth gear (4th) I calculate an overall ratio of 123:1.

How'd you get such a high ratio?

10
42/16
42/16
42

stock arrangement....
10 to 42 = 4.2
         16 to 42 = 2.65
                  16 to 42 = 2.65
 4.2 x 2.65 x 2.65 = 28.94063

One or two members of another forum had calculated the ratio of YELLOW-CRAWLER ..

by adding the 4 th gera ((( 34 x 10 ))) and this ratio was 184 / 1.









8 tooth pignion...



Personally, I do not know how to calculate the ratio.

Cobra gives us other ratio in these links ..


See this..

Visited LHStoday. They didn't have any stacked (double)gears and they only had a 9 tooth pinion, so Ionly picjed up a set of shocks for the front.

So... 4th gear is on hold and Iam continuing work on the suspension, which is almost done. now. pics to follow.

Finished front suspension, but unable to test without radio... so I have a used radio on its way from ebay... along with a double motor ESC...

I'll install a new servo for steering when I get it.  I'm thinking of scrapping the plastic tub and fab'ing a new aluminum tub, revising the suspension some more... and only using the axles and body in the new version.

Anyway, here's where I am...










Thanks for looking.

kasteer ..

You did a great job on this crawler.[X(]

You are resourceful.

Make a metal frame is a good idea.

Good luck for the future.[8D]
