Ok, just turned my wtt on to double check the placement. The board led is NOT at the end of the board,it is in the center, right behind the main shafts. There is a tiny little square led there that sends the green light. You can't really even tell that it's the led unless you turn it on and look right at it. If that led isn't turning on, then it's not the problem, you either have a dead board or dead heli battery. Something else that I'm thinking, granted I'm a little rusty with that heli since I haven't been able to fly it in a while, are you sure that you're turning on the remote with the throttle all the way down? If your throttle isn't all the way down, (which is mostly only a problem if you have removed the throttle spring) then it will also turn the led on the controller to red or flashing green. You could also have a broken connection somewhere within the remote, also causing it to turn red.

Thinking about it, how fresh are the batteries? I think the led turns red when you have older batteries about to die in it and it won't work for the heli any longer. I want to say WTT/real helis will only work when the batteries are good enough, then the led will turn red when they're down. (the fakes just stop turning on when the batteries are dead dead) I don't have my helis wth me at the moment to double check, but I think that's the problem with the remote.

That should be the problem there.

Sounds to me like you're looking at the green plastic led-looking reciever. On the very back of the board, sticking out of the frame, is a little green square thing that looks like it's an led, but it's not--it's the reciever for the infra-red signal.

I have a WTT s107 also, and it can be tempermental to try to bind. That's most likely your problem. You have to play around with turning on the heli, then the remote, throttle up, down, up, turning off the heli and remote again and turning on remote, then heli, throttle up, throttle down, throttle up and so-forth until you've figured out what combination your heli likes. That said, I do remember my wtt having a green led on the controller, not a red one. (been a little while since I've flown that one since it's speed modded, which isn't great for in a college dorm, and the one spring in the remote's jerry rigged with a spring out of a broken pencil)

I would still say the primary thing to do is to just take 10 to 15 minutes and figure out what combination your heli likes of turning on the remote and heli before binding. ALSO--make sure to let the led on the heli go from flashing to solid before trying to do anything or it will do nothing. (that's it setting up and calibrating the gyro for that flight)

Hope that helps!
