I want to buy rc helicopter. Where good place buy low cost rc helicopter?
I usually buy rc helicopter from http://www.xhobbystore.com/. Is there anywhere else cheaper?
Answer
This is actually an infinity question.
You probably should ask what kind of RC Helicopter do you want first. Big, Small, Indoor or outdoors?
If you are a beginner you probably looking something that's hard to break.
The good news is that Radio Control Helicopters are available everywhere from Amazon to eBay and cost goes to every budget, from $12 to $100s.
That just makes a question of what do you want to buy.?

How can I hook an electric ac adapter to the charger instead of using batteries?

Hello,
I need an electrical engineer here possibly to help with this. I have a small rc helicopter you can view it at:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=160299062598
My question is this;
The remote also charges the little helo with a short wire that plugs into the underbelly of the machine. The remote requires SIX (6) AAA batteries and I am burning through them like crazy. I know I may would be able to buy six rechargeable AAA batteries and a charger, but I dont know if that would hurt the copter, also, those rechargeable batteries and the charger are more expensive than if I could rig an ac adapter up to the battery compartment, I already have plenty of misc voltage ac adapters from other toys etc... that I can use. I am thinking I could somehow strip the wires and hook one up to the battery comp. at the north pole connector and the other lead to the south pole springy connector in the remote's battery compartment. but i dont wanna hurt the copter or blow myself up etc.. Is there some way to do this? I am not an engineer or anything so layman's terms please. thanks
I do have a NINE VOLT ac adapter but what does "mains in" mean?
It is only 700 ma though instead of one amp
is that ok?
There is no place to plug an ac adapter into so I will have to solder the end to the wires that the batteries supply current through. Also, my 9V ac adapter says 300mA instead of 700mA sorry. IT is small writing it was mistake to say it said 700 earlier. thanks
Answer
6 AAA batteries will put out 6*1.5=9V. So you need an adaptor that has mains in and 9V out.
Based on your description, I would guess that you need no more than 1 Amp of current. Your AC adaptor should therefore have more than 1A capability. Adaptors are often rated in milliamps or mA. 1000mA = 1A.
OK, I'm assuming that there is no dc-in socket on your remote control into which you can simply plug your adaptor. If there is - job done. If not, read on:
Open the battery compartment. You should see that the batteries are connected in series, with the negative (-ve) end of one battery connected to the positive (+ve) end of the next.
The wires connecting the batteries are usually visible in the battery compartment.
Locate the two extreme ends of the series string, note which one is +ve and which is negative.
Next take your ac adaptor. You need to determine which wire is positive, and which is negative. This is usually marked on the adaptor, or on the dc plug. The +ve terminal will be marked with a + and the -ve with a -. You may find that only one terminal is marked. Often a picture of the dc connector is shown.
Open the connector, if moulded with a sharp knife (ask an adult if you are not an adult). Now determine which wire is +ve and which is -ve.
Finally cut the conector off , bare the wires about 1/2" and attach the wires inside the battery compartment. +ve wire to the +ve end of the battery string and -ve to the -ve.
Job done.
If you want to be tidier, open the remote and solder the wires into the PCB where the battery attaches. Pass the wires through a small hole in the case (drill one), and add an in line connector (like one off a 9V battery, you can buy them on line). These things require a much higher level of skill though.
