Alientech Duo II hardware install for Mavic 2 RC

I finally took the plunge, watching the Chinese supplied Youtube Video was quite helpful really ( thank God for the subtitles ) I was a bit nervous stripping down the original RC unit ( I have recently purchased the Smart Controller, but didn’t want to risk damaging that ) took about an hour with little gaps inbetween to study the video or rewind a few times to check where the left over screws came from etc, the hardest part I thought was getting the original antenna sticks out of their mountings, the method the Chinese guy demostrated looked much too risky for damge through slipping etc, I opted for a small flathead screwdiver to wedge them out.
By the time I finished it almost dark, but I did a quick test flight in the freezing 1deg C outside temp & it worked fine, so no controller damage, I haven’t done a proper range test yet, but I have my smart controller to compare against, luckily they are both paired to the Mavic 2 Pro so really easy to use without having to pair one or unpare one depending on what I need.!

Nice one @Tony92 - thanks for sharing the details and pics!

I had the exact same problem when I did one of mine a few years ago.

I’m assuming they’ve not changed the antenna mount system since then :roll_eyes:

You’ll love it though - it blasts through any local wifi interference like a demon!
