Sorry but the link only takes me to the RC-Fever website. Am I missing something?

 

But thanks anyway. And like I already wrote earlier, my S107G is already flying again and survived many crashes since the last main shaft repair :-)

I am sure I have a wiring diagram ( schematic) somewhere, but I have tried to find it and to no avail, but I do remember Raptor gave me the link.

Very sorry I cant be more help but I will keep looking for you.

In the mean time my heli is flying again. I got the main shaft delivered in 2 days (from a different Dutch shop by the way, also good: http://www.rc-toyshop.nl/) and as a first timer it took me about the same time to fix as Supernovas video :-) Next time I will be quicker I am sure.

 

BTW: when I was working on fixing the loose wire, another wire broke off from the PCB during the re-assembly of the heli. This happened twice so I guess I (like a Dutch phrase) my helis PCB "was assembled on a Monday morning".

I've fixed the instability problem because of the broken pins before. You can just get another main shaft for a few bucks, and it's a five miute job. SN takes longer to explain what he's doing than the whole job takes.

You could buy another heli and part this out out in the long run, but that's a cheap part and wouldn't take much to repair.

I ordered my heli online at Dutch RC Helicoptershop. I got it delivered within two days (around Christmas time!). Two weeks ago I ordered spare parts and they even delivered within one day. Yesterday I called them asking them for the wiring info which they emailed within an hour so I am very happy with them.

In the mean time I figured out what causes my stability problem, thanks to Supernova's video on repairing the Main Shaft. The pins of the main drive rotor have broken off during the crash so I have to order spare parts again (I might be cheaper off ordering a complete spare S107G).

BTW: I tried to post the PCB picture in the Stop Thief topic but it is locked. Probably not for you as admin so if you can please do so.

Well, thanks for that! I'll have to keep that one in my back pocket in case anybody asks for one in the future!

Where did you get your heli from? Sounds like a good supplier to me. You should probably post them and the diagram over in the "Stop Thief" topic where we list good places and bad places people on here have bought from.

Hi CPD,

 

Thanks for your response. Impatient as I am I called the supplier from which I bought my helicopter. Within minutes he sent me the following picture which I would like to share here. In the mean time I have been flying again for a few minutes but after one crash I now have a control / stability problem (I have seem to remember there was another topic describing this behaviour so I hope to solve that one without having to solder again)

I could be wrong, but I haven't heard of anybody making a wiring diagram. They need to release one or somebody needs to make one.

There could be one out there from before my time on the forums, I just don't know of any. SymaFreak should be able to help, though. (wiring's not really my strong point)

Hi,

Since a few weeks I own a S107G helicopter and I learned to fly it quickly. However suddenly in mid flight the top blades stopped running. After watching most of the movies here I started disassembling the S107G and finally discovered that the white wire of the rear blade motor came loose from the PCB. My eyes are not too good and I need reading glasses / a magnifying glass. I am not 100% sure where to connect it back to.

Is there a link to a circuit diagram, a wire connection diagram or pictures maybe? Otherwise can someone give a description on which wire should be soldered to which PCB terminal (and on which side).

Thanks in advance,

Jan

PS: I found the topic on the Syma S107 Wiring Diagram but only one link was still working and the pictures there didn't show the wire soldering points (http://syma107.com/forum/gener.....g-diagram/)
