Hi friends,
Today got my Spektrum Dx7s. The only thing missing in this Tx is the 'Backlight' . I've googled regarding this and found that there are many kits available in the international online stores. Any body in this forum modded the Dx7s (backlight mod). Any suggestions ? Veterons please guide me.
Thanx in advance.

One of my friend Bilal had recently installed backlit on his Turnigy.
You can ask him or PM him.
Just a suggestion, why do you want to open your new radio... I mean a new spectrum... Grin Grin

i believe tinkering with your own radio sometimes is a precious moment far beyond the understanding of others.  Grin

if u really want to, see this http://www.rcindia.org/radios-and-receivers/avionic-rcb7x-review/25/

I think it could be done using the HK (9x) one too.

i have never seen a spectrum radio, so i dont know the screen size ,but dhruva must have seen it and if he approves the turnigy 9x  backlight it must be true, slight here n there you can do urself.
or
if u really want to go unique then use leds behind the lcd, u can install multicolored lights with some cool effects.

its basically a timer circuit attached to the backlight. the reset of the ic 555 is connected to the buzzer out of the radio. n so every time u click something a beep sounds starting the timer and powering it for whatever time u have set it for.

note: if u disable the buzzer this timer won't work
