Super Rooster Problem?

[Cake Eater]

OK, I'm not sure what part of the electronics is the problem, but i'm leaning towards the rooster. But at the same time my battery pack.
first the situation and set-up.
I wasn't actually crawling. Just driving around on the sidewalk showing my little cousins. Lots of going around in circle/figure eights and back and forth stuff withe the occational curb climbing.
As for my Set-up... Clod axles(locked), Super Rooster, 2-Hitec 645MG servos, 2- Integy Lathe motors, 8-cell A 2500mah.
The problem is:
I was running the Clod crawler around and after just a little bit it would stop just after I turned the steering. As in no throttle responce. Then after i would let off the steering i was able to use the throttle again. A couple of times after letting of the steering i still couldn't move forward and reverse. I also noticed that the steering didn't go back to center, but as soon as it did I was able to throttle.
This seemed to be only an off and on problem like when i was at full throttle and steering A LOT. But when i would just drive it straight through the yard and turn left or right, then drive a bit again then turn, It would act perfectly fine.
I've never had this problem before. The only difference I did compared to any other time is take off the high-strength servo savers and go to a servo horn.

I think i might just try going back to the servo saver again and see if the problem stops.

Anyone else have a similar problem? Or ideas?

THANKS!! :mrgreen:

Have you tried driving it again with a freshly charged pack?

what radio?if it doesn't have epa with the horns may cause more draw seeing that the servo can't go to it's end point.with a saver on the saver would flex at that point alowing the servo to go to it's end travel

Sounds like you SR can't push out enough juice to supply the servos and dual motors with enough power. As you are turning the BEC is sucking the life out of that small pack you are running. In a Clod or any other "big" truck you should run Sub-C cells, IMO.

Try running a "normal" pack(Sub-C) and see what happens... I'm betting that you are demanding more power than what the SR can deliver.

You need to run a seperate rx battery pack OR straight wire your red wire from your servo's to the red wire on your battery. Basically your rosster isn't pushing enough power to run both servo's and the ESC at the same time. I have had the same problem and someone told me what I am telling you. This will fix your troubles. :mrgreen:

ummm i not to sound stupid but whats an rx and how do you run a separete pack to it?

Thanks guys for all the info... I did forget to mention that the battery pack was completly charged. And i do too feel that I should upgrade to a bigger cell. Just trying to save room and weight on my Stick chassis.
I didn't even think about adjusting the EPA. As I remember when running it, it would only have that stall problem when I had the wheel turned all the way. And when I would run it in the open it wouldn't stall at all, probably because I wasn't turning the wheel all the way. That makes total sense to me why it did work with the savers on.
I'm going to try putting back on the horns (already put back on the savers). And adjusting the EPA. (radio=Futaba 2PL)
Then for some reason that doesn't work, I'm going to try a different battery pack(SC's). I'd like to stay away from an rx pack, SR should be able to handle that with the other adjustments I just said.

Thanks again!! :mrgreen:

rx is short for receiver. And you can purchase small packs that plug into the receiver to power the servos by itself. But most speed controls have a BEC which will run power to the receiver and servos useing the main battery pack.
Hope that helps.

 

[AQTHF BIATCH]

ooo, ok that makes sence, can i do this even with the bec?

 

[Cake Eater]

I believe so... I've done it with other speed controls and never had a problem.

You've only tried one batt pack for this testing?

I'll bet anything that you have a bad pack.

I actually have three packs that i rotate. 1- 8cell A 2500 mah, 1- 7cell A 2500, 1 7cell 4/5A 2000 mah. I even tried using my 7-cell SC 3300, but it was a flat pack for my TC4 and the wheels would rub.

They all work just fine.

I've already changed back to the horns and messed with the EPA's. And so far nothing's gone wrong. Seems to be no strain on the servos at all... That is in the living room and rest of the Apt. haven't been outside yet, been raining since I've been able to work on it.

Thanks for the suggestions.
I'm gonna try this out as soon as the weather is permitting. :mrgreen:
