Yup, Rick. That's where I'll start looking.

The lower blades are connected to the outer shaft (of the coaxial), which is connected to the top gear of the gear box, which is driven by the front motor. If none of these things is turning when throttle is up, and that the motor has not seized so that you could still turn everything by hand, then my first suspicion would be a loose motor wire. Open up the canopy and check the wires connecting to the PCB.

Below, you will find a wiring diagram for R3 for your reference. R5 is the same.

I just repaired one like that Saturday for a kid. The front motor negative, blue wire, 2nd from the bottom of the picture was stripped and cut by something. The wire was cut and the insulation was hanging by a thread. I had to cut it off and re-solder the now shorter wire to the PCB. After that, the lower blades were spinning and the helicopter flew like new!

Sometimes, IR signals are subjected to interference. Perhaps you're flying in a "noisy" environment (in terms of IR interference) and your control range is shortened to just a few inches.

But, it is perfect possible that there is no difference between the first flight and now. Something could have malfunctioned on the Rx side, and the sensitivity has gone down the drain. It has happened to me.

It seems to me that you've done everything right and checked everything - battery, status light, active signal, etc. If that's the case, just see if you could return it for an exchange ASAP.
There was no difference, I don't even think it ever worked better than how it does now.
I also turned off tv, etc. etc. even with ALL electronics off (even lamps), it didn't even make a difference.

Unfortunatly I don't have the right screwdriver to get it off.. maybe I can get one later, I will let you know.

I flied the heli untill the battery went dead, if I stay (VERY) close, it works, but I have to stay at the back of the heli.
It was fun, although it lost contact a lot when it went too far away
I will try to contact the website I bought it from, I hope I will get it to work!
Thanks anyway for the help! I will let you know how it works out haha

Good luck, Billie Banaan. Yeah, see if you can get an exchange before you pop the heli open. If it's new, I'd go that route first...

Okay. I does sound like you have an inferior bird. It happens. I have one of those and I'm exchanging it. Good luck with yours.

hey guys, sorry I havent responded in a bit but I ended up with strep throat and havent even felt good enough to browse the net with a laptop on my couch till today lol.

little heli is still working and yeah, probably should not have left it on the charger overnight lol. so I can unhook the tail fin and no adverse effects AND it'll go faster? nice.

on another note, I live in the dirty south (charleston, sc) to be specific and its bloody hot. we have ceiling fans in every room and man if they dont screw with the poor heli.

are there any other affordable (comparitavely priced) helis that react better to indoor fans and have decent battery life?

not saying I'm getting rid of my s107, I intend to run it to pieces and then sell the salvage on ebay as I do with everything I own lol. I just want something that can cruise better through my house and for a bit longer than 3 minutes before it starts getting funky...

Quite frankly, I think most of indoor helicopter of this class has more or less the same flight characteristics. Small rotors could never really compete with the ceiling fans. You started with one of the best in class. Unless you have the desire to experiment with others and ended up sourcing a bunch of different parts, you'd probably better off sticking with one model. While you're not using the fan, try and learn your helicopter on top of on the fan blades. It's a good challenge!

@stackz : I have air conditioners in my house and I actually have a good time flying my S107s *through* the air stream and riding it like a little surfer (well..sort of--more like a good PUSH). I haven't tried them with my overhead fans, but that sounds like it would be interesting.

As for the battery life, my solution is just to buy a couple more helis so you can grab a new one when the battery on the other wears out. They've got 5 different colors to chose from and there are some nice "scale" replica models (S102G, S108G, S109G, S111G, S026G) that you can collect if you want as well.

lol, dont have the room for multiple helis. I live in a traditional 1940's charlestonian "cottage" home. I keep my s107 in my sock drawer, only reason the finance allows me to have it.

I guess my worst thing with control is keeping it at a steady hover due to the fans. also, it doesnt like turning so much. I can fly it pretty darn good and land like cake but man, it gets caught in the air streams between rooms and when its about under the main fan blades. when she's not around, I turn off the fans and turn down the a/c but yeah...gotta hate the increase in the electric bill haha.

I love my blue color scheme on my s107...and paid a bit extra for it just due to rarity apparently. but then again, blue is my favorite color haha.

I've seen some of the youtube videos on battery/speed mods, just dont know which ones are good/bad.

and this thread is over 780 pages long, way too long to read through for me with ADHD sigh.

Give up the source where you got that or I'm gonna think it's photoshopped.
