A lot of you already know the value of a smoke stopper. Much of this is nothing new, so I will not go into the details of how to make one. There are plenty of posts and links you can find. 

I wanted to make this post because I added a switch to my stopper. Have you ever tried to hold down the bind button on your RX  with one hand and plug in lipo with the other. You are almost bound, the RX led is about to turn green and you loose grip of the lipo connector and now you have to try again. With the switch, very simple modification to your stopper, you can easily bind. 

Here is a photo of mine. 

That is an awesome idea!
