OT - anyone into R/C?

no estwing?

Almost no experience but I have seen this with the cheap Nikko (shh) J**p thing I have, when (nearly) out of range.

Not your batteries (Rc or TX) starting to go down and thus reducing range is it?

Just something cheap and simple to try before going to far.

Is this a fully assembled jobbie, or one made from components ie seperate radio and kit and then you assemeble to the whole lot yourself.

If the former, then you have a problem, unless you know a fair bit about electronics. I found the performance of my kids cheap nikko was dramatically reduced after it was tested in the bottom of the pool.

If on the other hand it is a built up model, then you could try switching the speed and steering servos - although these days I gather that a lot of the speed controllers are electronic in which case you would have to try and borrow/beg/buy a servo to try it out with.

Sounds like a duff servo. Inside the servo is a little potentiometer, which I guess has either got a broken track, or has shit on it somewhere. The pot tells the motor where it is, the motor drives until the pot says the position is "right" by comparing it to the signal from the transmitter. If the pot is knackered, there is nothing to compare against.

Yup, my money's on the feedback pot too.

In my hands, everything becomes an estwing eventually.

Thanks. Batteries all good.

If it was a real vehicle, you wouldn't hold onto your lunch. Imagine going over rough ground with the driver spinning it from lock to lock with a frequency of about 4Hz. OK, not imagine but remember ... :-)

It's an assembled package. If I'd built it myself I might have an idea where to look, but I haven't even taken its bottom off. If I can identify the servos I will try switching them, thanks.

Many thanks - that's where I'll start looking. Are these easily replaceable/obtainable?

A picture would help.
