I just got my i8 and wanted to share what is inside the black box. only 4 screws on the back to remove. A GD32F130 is running the show and there is a Silabs SI2102 on the USB port, so it is not only for charging the Nokia style battery. The RC part is a FlySky FS-HF030B.

RC part= RF part. Damn you, autocorrect!

Man, there is not a lot going on inside there!

Yes, you can shave off quite a lot when you don't need to drive an LCD and some buttons for the interface.

What do you think about the general quality?

Will you test C2 link/communication?

Hmmm, with an Arduino mini you could replace the 6pos with 6 buttons.  Light up buttons, even.  Heck, one of the buttons could have a flip cover over it.

How was the process to change to mode 2? It looks like stock is mode 1.

Thanks for the peek!

Alex: It is very close to the CX-20 radio both in size and general feel. It is very light. Probably due to the small battery and the general emptiness inside. The rotary switch is surprisingly small and you need two fingers to turn it. You cannot give it a nudge while still holding the stick. The LEDs have a nice christmas feeling and cycles between red-green-blue-yellowgreen-orange. Feels totally usable for 50 bucks. Will mess with USB later.

Tedro: i ordered it as mode 2. Looks like it is simple to convert to 1 (move spring/move metal plate).

I think the stiffness it's a good thing for the rotary switch, so you can't change the flightMode accidentally with big fingers or winter gloves.

I will stay tunes for further info.

How bout some peeps jump aboard the Flysky i6 Mod page: https://github.com/benb0jangles/FlySky-i6-Mod-

We have already released our own firmware updater to increase #ibus channels, but we want to also allow Ardupilot telemetry.

Project goals:

Project goals:

  • Increase number of channels (using PPM or ibus) (Done)
  • Enable Mavlink/APM Telemetry (using ia6b receiver)
  • Ability to edit TX Voltage reading & alarm (allowing lithium battery power)
  • Edit duration of 1 minute 'inactive' alarm (Done)
  • Functional Flight Timer
