Hey every one my name is Terry and Iam new to the rc and drift world, I have a HSP racing on-road drift car that is having some issues with it. Ive had the car for about two weeks and has been doing fine until today. I have the battery that came with the car and two that did not. the two spairs that I have are the same voltage as the new one but the mAh are diffrent by 200 more, but the issue is when I took it out to a bigger running area the car started actting funny. When the car was sitting still and I would turn the wheel with out pulling the trigger it would want to move and the only way to stop it was to pull or push the trigger the oppsite way that the car was going. Iadjusted the trim so that is not it. what eles could it be.

Thanks for the help
Terry

Sounds like interference of some sort, or a dodgy aerial lead?

Yup. Sounds like interference.

If the car is using an AMset up for your transmitter, you will receive signals from all sorts of sources. This translates to your car, and will make it do some weird things.

If you plan to stay with drift for a while, get a 2.4 Ghz (gigahertz) system. A basic one can be had for less than $100. That will ensure you never have that issue again.

so a cell phone would cause i to do that

Sources of AM transmissions. I don't think a cell is one of those.

Even high-tension power lines will emit interference. There are many sources, which is why 2.4Ghz works so well. It isn't locked into one bandwidth like AMis, but searches for the next available open one, so intereference can't affect your RC.

As I stated, if you are planning to stay with RC, geta 2.4Ghz system. You won't need crystals, or evencheck other RC people's bands, because you won't need to. There are many companies that are selling inexpensive 2.4 set ups. Hobbywing, Traxxas, Tower hobbies, etc. so you aren't stuck with spending a bundle on one, like it was when 2.4 first came out.

Get a 2.4 Ghz system, those problems you are having is a thing of the past. Period.
