Beginner needs advice

Not unusual I'm afraid. The Twister Storm manual has quite a few faults. There's also a lot that you need to know that doesn't get written down.

That's disgusting. My problem with the Honeybee 2 manual has cost me a lot of money.

Whilst I'm new to helis I've had a lot of cars and a couple of boats so I understand radio technology.

If a car or boat motor runs the wrong way they go backwards so even to a newbie can see the problem but with a heli it makes it difficult to fly and results in crashes.

If the manufacturer was in the UK I'd be starting proceedings through the Small Claims Court.

There's a lot worse I'm afraid. People seem to bin things now if they have a problem. I don't, usually, as I feel that if sellers are allowed to sell rubbish that they will continue to do so. You have a claim against the retailer. I have had problems with someone in HongKong who sold Walkera helis. He was very good though. There was faulty soldering on a rx aerial and it was too small for me to correct. He asked for a picture and agreed with me, apologized and sent me a new rx. I've just had a refund from GiantCod for something faulty, even though they couldn't find anything wrong with it. It does help being a retired electronic engineer. One person actually apologized for talking b.llocks after I told him I had a degree. That doesn't mean though, that I understand what is going on. The main reason is that the information is kept company confidential. There is no interface information for servos, for instance, so you can't tell if a rx will drive a servo. They do usually work, but there is no spec that I have found for input impedance, switching levels, rise time of input signal or maximum input volts. There are similar vague statements on voltage supply. There are 6V servos, but no figures on what that means. It could be an absolute max figure, or a working figure. If a working figure, I haven't seen an absolute max.

With experience we do find out what works with what. We have recently had a thread that resulted in the expensive cyclic servos supplied with a kit being replaced by much cheaper ones. There was no reply from the manufacturer.

This is general and not a comment on the present post or poster.
I am happy to advise anyone on or off forum if they have a problem with getting things replaced. It does help if you can describe what really happened, a link to the product with the problem and any measurements taken. Being able to measure volts with a cheap meter also helps. Most suppliers will do refunds.

Wait, what? Even I have managed to drive servos, and I have no idea what I'm doing really! I've never had a problem with a quality servo not working with a quality receiver; has anyone? The standards are de facto, but have seemed consistent to me.
