A solder blob could short to the chassis, but the chassis on my S107G is non-conductive, even though it has all the appearance of a conductor. So, that alone should be a problem.

Clones


I know this has come up before but so many threads.
I bought two Syma s107 from the same UK supplier-both in S107G boxes but one in green marked on cockpit S107G Gyro system and above 3D full function helicopter.
After about 120 flights and a steep learning curve its hiccuping a bit.
The other I have just got out of the box and started to run after stripping extras of tail and fitting a picoos tail rotor.
Thing is second one just feels to fly better than first-its yellow and just marked S107-think it might be the clone but if so a far better build.
The problem is and I know this from researching Anchor Windlasses for my yacht in China you will get a company who assembles and markets a product but who buys in the bits from other companies who are quite prepared to do business independently.So in the case of windlasses and I am sure helis you can not only get Chinese branded products but US and UK branded products and if you are prepared to buy quantity you can have your own branded product.

Put a little piece of thin insulation between the two. I had to do this with one of my helis. I just used a yellow piece of insulation that is on the spare batteries.

I had a S107 that would just not charge (or seem to charge) and the heli could never make it off the floor. I discovered the red wire was up against the metal frame. I used the fix described in post # 12783 and all was well.

Yes, Mike, I remember you sharing that experience. I'm not quite sure how that worked.

When I put my meter on the metal frame of my S107G (quite a few of them), it not conductive. Even if it was, the -batt terminal bunches up against the left frame and the +batt terminal bunches up against the right frame, which are isolated from each other by a plastic frame in between, what does that has to do with anything???

So, what I'm guess then is that you have a cold solder joint, and the wire is not making good contact with the board. Whatever isolation you put in, or during the process of putting it, just moved things enough to create pressure necessary to complete the circuit. Wild guess, I know.

But unless I get your helicopter on my bench here, I could only offer you theories. And those theories are thin, I'm aware. If it ain't borken, leave it. Go fly!

BTW, my S107 and I went for another hospital visit today. Senior lady fell and broke her hip. You should see the big smile on her face when the helicopter came out!

My S107 flying skill is getting really good here. It goes with me to the hospital all the time. I fly circuits in hospital room. To date, I haven't cut any IVs or killed any one.

s107H and s107N


I did some checking on the new helis from syma. The s107-N and the s107-H. What I could get out of my parts suplyers is the s107-N will be available very soon. On the s107-H 2.4GHz
Well all they could say is it might be the replacement for the s107-G. They will be using the same parts, frame plastic main body and motors. Itís the 2.4GHz that will make the helis better. For me using a 2.4GHz transmitter instead of the inferred means I will be able to run the heli out doors and farther away from the TX. I need the extra distance do to the increase in speed. They also said to be very careful on the web sites that offer you to prepay or preorder.

If you have bright sunlight or a plama television on or any bright lighting in the same room then they can all cause the signal to be lost and your S107 will drop like a stone

Surely chassis are aluminium and whilst not a good conductor of low voltage is still a conductor.Works well enough on high voltage power lines!
I suspect that short is from side frame through the charging plug as mine is now running when I try to charge!
