I would like to know if you can mount the esc to close to the motor. If so would it cause stutter and cogging. I had such a problem and was wondering what causeing it. I have eleminated the problem with motor, esc and reciver. Could it very will be possible that the problem is coming from the magnetical force of the motor? I know electronics can be sensative to mangetic force.

The controllers are usually supposed to be placed as far as possible from the reciever, batts and motor to prevent interference, though I'm not very sure about it.

I also read that the shorter is the wires between the motor/esc is, the better, so I dont think the motor is the problem.

I am not sure if it would cause trouble, I had a hacker master comp next to a basic 4200 in a xxx-4 and had no troubles, only thing I have had trouble with is using bec on a warrior controller and rx too close to esc

Yeah, problem should not occur from a short distance between a motor and a esc. Probably your controller needs to be checked.

I tried other controllers. 9920 and a 30150 all of them did the same. The only one that did not have a problem was the schulze. It would not support the cell count wanted to run. I tried different receivers and transmitters to. All seem to have same problem. Even mounted another motor on it. It did better but still had problems.

The reciever's wire might be contacting the chassis. Its aluminum chassis, right?

coolhandcountry · 01.16.2006, 08:02 PM

I have tried about 5-6 different receivers. I don't think all them could be touching. I did check that out. I even went over the truck and tried to find loose screws or metal parts rubbing. I found one and fixed that but didn't help.

The positioning of the motor in relation to the controller shouldn't have an effect on radio interference. But, wires could cause interference, as well as servo wires. Have you tried shielding your receiver with aluminum foil?

Cool on my EVO & maxxes my motor and speedo's are side by side with no issues eveb on my CF chassis.

I'd try shielding between the motor and esc to rule it out.Have you tried a reciever pack?Maybe the BKs affecting the UBEC more than the schulze.

coolhandcountry · 08:32 PM

I have tried a ubec and receiver pack. Both has some results. I have the receiver in a aluminum housing as well. I tried it out of the housing. I have tried bench testing with out a servo on it. No good. The only things helped was another truck. I thought about trying the spektrum system to see if that would help. It is only a few hundred bucks. :D I be happy if it fixes it. I would dance a gig. Well any more suggestions would be helpful. Mike has been working with me for a while on this. I don't know how to repay such a great fella for his time. Thanks for ya'lls to.

Bench testing was done on the truck.

One other thing. I can drive the truck cold. As the truck runs around and warms up it gets worse. It will get so bad that the truck won't drive over a small pile of leaves. Would maybe the spektrum fix this as well. I am lost and confused on this one.

This is your center diff maxx, right?
Can you try another motor?

Gustav · 01.17.2006, 10:14 AM

He tried another motor and other bk controllers,seems the truck doesn't like BK controllers for some reason.Works with the Schulze.It's a puzzler alright.
