Hello! Just a question: Why to make this modification? We cannot directly plug the backlight in the transmitter?

Thanks for your response and thanks for yours others step by step videos.

@fioulmaster Hi! With this mode you can control back lightning with settings in Er9x firmware.

I have 470 ohm resistors lying around. Can I use this to bypass the built-in transistor directly to red wire to the back light instead cutting the track on the pcb?

@spiro9210 hmmm, Sorry, I don't know, but you can try it :)

I have some C945 and C144 transistors that I salvaged from old circuit boards. Would either of these work as a substitute for the BS170 ? Thanks for the instruction video. I put my backlight on and the radio wouldn't power up and after much searching I discovered one of the crystal pins had never been soldered on and the radio only worked because the original foam was pushing the pin over to where it made contact.

You are the best my friend. Thank you as always for everything you do.

@ssanfelix No. Both mods (cut of track and wire bridge) are for this backlight/simulator situation.

@richardmrazek

Thanks. then i don't cut the track, but is it necessary the wire bridge between resistor and pin3???

[richardmrazek]

@ssanfelix exactly. Only for backlight on simulator/trainer cable. If you dont cut it, it will be works during standard flying without any problems.

[ssanfelix]

Is it necessary to cut the middle track? Or is only necessary for simulator runs without backlight?

Thanks
