Are there any small RC Helicopters that use a button cell battery, rather than a rechargeable battery?

Q. I am currently temporarily disabled and was looking at small RC helicopters to entertain me. So far, all of the small ones that I have seen use a rechargeable battery that has a ~2:1 charge to flight time and seem to lose their capacity fairly quickly. I am looking for a helicopter that uses a button cell battery rather than a rechargeable one. Another alternative would be if it would be safe to modify one of those cheap helis to use a button cell.

Answer
as far as i'm concerned, a buttom cell does not provide and it will never provide enough power to lift a helicopter out of the ground. (we're both talking about toy helis right?)

you might modify one helicopter and you COULD get the blades to spin but i doubt that you'll get it to fly. it is worth a try with 3 buttom cells.

I would try with 3,4 or 5 buttom cells connected in series so when the drop off voltage kicks in, the heli flies at least for 10 seconds with no problems......

RC HELICOPTER EXPERTS!! THIS QUESTION IS FOR YOU!?

Q. I just ordered a Syma S108. They look very fun and cooler than the S107. What your opinion? Should I have bought the S107 for $22 or the S108 for $30?
Thanks God Bless.

Answer
i have never heard of this model however after looking up the model i can tell you this they are both mini / micro helicopters.
these micro helicopters are ones that are marketed towards people who are new and or just want a cheap helicopter to try out the hobby without sinking much cash on a helicopter. its also smaller and can be used in small spaces compared to full size helicopters. this model should be easy to fly due to its design.

in terms of s 107 vs s 108 they are pretty much the same and you would not see much difference.

the 107 has a larger battery though and could fly for a few minutes longer.

i would say the s108 is a good choice if your only spending like $30

is this your first helicopter?

if its your first helicopter and later your interested in something more challenging or larger you could go with something like what i did for my first RC helicopter that was above the lower entry level. if your interested in something priced a little higher but could perform better.

this is what i did with my first helicopter.

I own a thunder tiger mini titan e325 3d its electric and i found it easy to assemble( having never done it before)

i liked it and with help learned to fly using it.

you can find this helicopter at many sites

tower hobbies is a good place to buy from
http://www.towerhobbies.com/#

theirs lots of other places you could buy from too.

i would go with electric to start off. gas can be more complicated.

word of advice don't just buy the helicopter find someone willing to teach you how to do it without destroying it.

sometimes they can even help you set it up.

local RC clubs may be able to help you get more info on the hobby.

trust me get help learning so that you don't crash.

its a great hobby and once you learn can be great fun!

so the 107 and 108 are not to different. i wo

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

perryinjax

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.
