Spektrum Dx7 Power on LED

On more then 1 occasion I've been woken up by my low voltage alarm going off on my Dx7 because I forgot to power it off after setting up a model, etc.. Other then a bind light on the back of the Transmitter, there's no power light to remind you that you've left it on. So after some research on the forums, this is the easiest way I've come up with to install a "Power On" LED. Step 1 is to remove the battery and the 6 screws on the back of the DX7.

Description: . Next locate position "J5" on the board you just removed the 4 screws from. you'll notice i've already got the wires soldered in. Position 1-J5 is a positive and the other 4 are negative. With a meter I got 3.2 volts across here. Perfect for a 3.2 volt L.E.D. Name: 2014-01-20-18-54-11.jpg

Description: . Solder on an L.E.D. of your choice and choose a location for the L.E.D. Drill carefully! I decided to drill directly through the SPEKTRUM label on the top/ front of the TX. There is nothing in the way if you drill here. Then I just held in place with some hot glue.Name: 2014-01-20-18-55-54.jpg
