Sorry to start this off with the fact that i am a bit of a noob with drones themselves, however am quite a nerd in lots of techie things and am so happy to be getting into this, but bare with me! Just got the 3DRobitics IRIS+, and honestly I love it but I wanted to make a couple DIY changes.
So, I wanted to mod my RC controller and add a backlight to it as I couldn't see a darn thing at night. I bought a hobbyking blue backlight, works great! Then i saw videos with this thing called...SmartiePants board. I guess it allows you to turn the light on and off. I have no idea how one would program to do so, but the install looks really easy, definitely do-able! I phones to 3DRobotics and they told me it shouldn't affect the programming they have in the controller for the IRIS+. Is this true?
How can I just program one of the back switches to turn that light on or off?
and my last question is this...I have a lame battery pack it comes with, and one port to plug it into. I see hobbyking sells 3s 2200mah lipo batteries made just for t9x rc's. Can I use this on this port or what would I need to do to get a battery fit in there?
