have you ever had your Spektrum DX5C turn on by accident from something bumping the power button? This happened to me all the time, so i finally did something about it!

Print this protector then super glue to the transmitter.

Make sure you don't have too much elephant footing at the base otherwise it may not allow the power button to move freely. make sure to dry fit first. Use a pair of scissors to open up the hole diameter if needed.

be careful to only use a small amount of glue, otherwise you will glue the button in place and you won't be able to turn it on! i used medium thickness gorilla brand super glue. worked great.

also make sure to use rubbing alcohol and clean the surface before you glue it down. this gives you the best adhesion.
