:shock: That has been a looong breakfast....:lol:

Looking good I can;t wait to see it complete with the tube chassis. I've just ordered the Yokomo crawler so I might have to try those cobalt motors. Can you tell me what turn rating they are?

What are you using for pinions on your motors John?



Mike

Same question as mike's here, i received the motors today and the cc pinions don't fit, smaller diameter shaft, are these 48 pitch standard? i know the pinions i have for the tlt and other rigs i have fit the 454's shaft.

I am using the stock pinions from the berg. It is listed on the 454 page, first line--

**For Cliff Climber use the stock Berg pinions work (mod 0.6). Stock Cliff Climber motors use 2.3mm bore mod 0.6 pinions**


These also work http://www3.towerhobbies.com/cgi-bin...?&I=LXFEA5&P=7

Yeah that's what i figured, i drilled out the stock ones (let's see how long they last) while i get some pinions.

Should work just fine. I got the truck all running, just no time to take pics yet. I am hustling to get ready for Moab.

Esc
 

Hi John, did tried the pullers with the stock ESC? And wath did you do with the battery cables that you said you use just one battery pack on the stock ESC? How you do it?

I just had the same issue. Did you ever get any word from castle on this?

On the stock ESC, the "b2" positive and negative power the BEC, so use those and you can have just one pack to run. You need to short the B1 wires to get power to the motor. The stock ESC does not run the pullers.

It is a bug in the firmware, they may not fix it and just update the manuals instead.

John, I eventually want 454's, but cannot swing them now, so I am going to volt up and gear down a little to play with this CC(couch climber for me).
I found 8-10T 48P 2.3mm pinions.
I do not know heli's, so I am not sure I understand the 0.4/0.5/0.6 Mod verbage??

What pinions specs are for the stock 380's? 2.3mm shaft. 48P?

What about the Integy 1/18 pinion sets
http://www3.towerhobbies.com/cgi-bin...?&I=LXKWJ2&P=7
I believe they are for 2mm, but could be bored out easily enough (using two drills).

The stock pinions on the CC are 2.3mm bore .6 mod. 48p is not the same.

You will not be able to use 8-10t pinions on the CC. I suggest you add weight to the front to help get more front traction. The stall occurs because it wants to send power to the path of least resistance......so if your front wheels are in the air or not grabbing, it will send more power to the front.
You can add weight to the front wheels, mount one of the batteries on top of the front steering servo. Just a few examples.
Hope this helps till you can get the 454's. They are awesome motors.

is the stall caused by the stock esc

Jdawg53,

Why won't I be able to run 8 or 9T? Is the diameter of the 8 or 9T pinions too small, so I will not get enough motor mount adjustment to mesh well?

What about T-400 for $8.99 at Tower? I cannot find specific specs, but supposed to have more power (higher wind count) then the S-400.

BTW, my setup is a LOT different then stock.

Could not get the stock tires off of the stock rims, even with HIGH heat?
So for right now, lead is around inside edge of rim in front.
Batts in back to clear front steering.

thx!

Stall is not "caused" by the esc. It is caused by the current flowing through the path of least resistance. If the front wheels are in the air or not grabbing then the front is the path with least resistance. So, put one of the batteries on the front steering servo and weight the front wheels. This helps ALOT!

You cannot use 8 & 9 tooth pinions because the motor mounts do not allow that much adjustability.

I have not tried our T-400 motor. Typically, the airplane motors focus on rpm not torque. I try to order a couple up and try them.

I know what you are saying about the tire glue. It is goooood!

hey john where has your lil truck gone.i was wondering if you had tried the 370 motor in your cc . dose it have the balls to do it. atomic has the pinions for the smaller shaft

Whats the easiest way to jump the 2 pins to run the single pack? I was gonna use a jumper pin like on a computer....it should work.

Will this pinion work for the CC with the 454's???

no. 32 pitch is much too course. john posted the metric pinions earlier that work.

Have the 2 Cobalt pullers driven off Rooster Crawler ESC
 

They crawl great, and same as cathocism (sp?) I snapped my axle innards the first serious time crawling rocks. I used 0.6 mod pinions from Towerhobbies made by Novak for fitment of their motors to Duratrax stuff. They sell a 3-pack of 10,11,12 (or 11,12,13) and I used the smallest ones. I also had to relocate the lower links the outer positions. I wired 2 6cell packs in parallel for extra weight up from, but also have a smaller LiPo 7.4V pack to run singly if less weight is needed. Can drop truck onto it's side on wheels and it won't flip over, so balance seems good. See my pics for my HomeDepot chassis in the photo gallery. WB is 11.5-12 inches.

links to these pinion packs please!!!!!!!

link to Tower for what I bought and used 11,12,13 tooth mod 0.6 pinions, work fine, no modifications at all for the Cobalts in the CC.

JRH, sorry for the threadjack, if you run 48 pitch gears, will these turn the diffs or will there be binding?

normal 48p gears will wear down the internals on the CC. It wont even be close to proper mesh.

would I be able to use that mamba micro with the stock motors and a single 3 cell 1320 mah lipo?
