Has anyone ran a 55t for the front and a 65t for the rear with the same tooth pinions like 8t to clear up there Clod Stall? The reason I ask is b/c I have two 8t pinions and one 65t already. Or should just buy a 9t and another 65t?

TwistedCreations · 11-09-2006, 06:34 AM

Well unless your gonna run 2 ESC's, it won't work very well at all....... The faster motor sucks all the juice, leaving the lesser of the 2 sitting there.

I tried it with a 45t and 55t and tried several different pinions. All the same results..Unless you have 2 ESC's, there is NOWAY around clod stall. JIA did an article on this and did several different routes and none of them worked.

If you already have everything why not try it. As has been stated numerous times, nothing "stops" clod stall. However, trying things like the different motors and pinions will change the point at which you experience the stall. My setup with 9T rear/10T front stalls at a different point than when I had 9T/9T or 11T/10T.
Jason's article proved the point that you will always have clod stall. I wish he would have done testing to what the changes did up to the point of clod stall. Maybe I will do that. Hmmmmmmm

I would say just try it, unless you were hoping to sell the motor as unused.

I am running, & always have run 45t in the Fr. w/ 55T in the rear...
I use 8T pinions & a TR2.

I get as much stall as I want, when I want it usually!
If I don't want it to stall, I just give a lil' more throttle...

It works great for me!

Ray is right. sence pulling out the TTR gear units I am running a 45 turn in front and a 55 in the rear with 8 tooth pinions . it work good for me .

666 · 11-09-2006, 06:50 PM

I run a 55 front, 65 rear, 8 tooth pinions, love it!

clod booster · 11-09-2006, 07:41 PM

heres another one, rc4wd 6 tooth pinions.

TimR · 11-09-2006, 11:24 PM

I was running a 45T in front and a 55t in back with rc4wd internal gear reductions and a super rooster. It ran great it almost eliminated cold stall, it would stall a little but give it a little throttle and it would go away. I changed to 2 45t's when I put in the 2nd esc.

clodstall · 11-10-2006, 09:50 PM

running 55 turn axle snappers thru evx with 14.4 and almost unstoppable.
oh yeah you guys cant get rid of me.lol

Flash Burns · 11-12-2006, 11:23 AM

I've tried two different approaches.

1. 55t's in front/rear with a 9t pinion in front and 8t in rear.
It worked fine.

2. 55t in front and 65t in rear with 8t pinions f/r. This setup worked best IMO.

Note: both setups were wired in parallel.

muddeprived · 06-15-2007, 02:48 PM

I had to dig this up because i am experiencing bad clod stall, bad enough for me NOT wanting to drive the truck. At first it wasn't apparent but after the rig got used a little, the stall starting showing it's ugly face and never looked away. Every hill climb has the front axle spinning and the rear sleeping until i give it full throttle. Even at full throttle, the rear doesn't spin as fast as the front. I am running 55t's and 10t pinions with an evx esc, 7.2v 3600 or 3700 batt and rx pack up front.

From what i read, clodstall is a result of electricity taking the path of least resistance so....if i were to drive up a hill, the rear gets the big load and stalls. If i were to drive up the hill BACKWARDS, the front should stall right? When i do it in reverse, the front never stalls out and the rear runs fine. What's causing the rear to stall when going up forward and not the front when going up backwards? If i were to hook up both batteries (will have to get the same mah battery) and run duals with my evx, will i be seeing less stall?

i hate clodstall.......(not you Clodstall

)

I hear you, clodstall sucks...(not you clodstall

), you may need to service one of your motors, check the brushes and comms.

Just did that two or three days ago. My rig's kinda heavy so that may be playing a role. Maybe running it on 14.4v (dual batteries) would wake up that rear? I do have two batteries but they are different mah's so i'll have to get a twin.

Running dual ESC's and batteries off the same throttle channel really shouldn't make a difference. It may just be a difference in the motors and how they are wearing like Cart suggested. I have had Integy 55T motors that performed very differently. I'd swap the front motor to the rear and go with it.

andrewmp6 · 06-17-2007, 02:05 AM

im thinking of trying the 2 esc set up do i have to run two batterys or just wire them both to one

DaViolentOne · 06-17-2007, 10:04 AM

2 55's with 8t pinions and an 11.1V LiPo won't stall very often.. If it DOES, it's bound up pretty heavy and a BL would snap parts in that kinda spot... One of the guys in our group here runs that way and he can go super slow up some pretty steep inclines with splits and cracks in the rocks and it won't stall out no matter how slow he goes... I've watched him and even once we tried to make it stall and it didn't... >shrug<

That seems like a good combo to keep stall down to a minimum... Just give the lathes more juice...

Seems like it's all about power. I'm gonna go dual-batt and see how it does.
