You need to download the latest MSH PC setup application from the download site.
It only runs on Windows.
MSH makes both the Brain and the iKON - they are identical except for the case.
So, don't get hung up when you see "Brain" or "iKON".
They also have the Brain / iKON 2 now.
The only real difference between the 1 and the 2 is the 2 has logging and a faster processor.
There is only one setup application for all MSH products
Install the PC application first
Do not open it yet.
Make sure you have a battery connected to the iKON - it does not get power from the the USB cable.
Power on the iKON and attach the USB cable
Make sure your PC is attached to the Internet.
Then, launch the setup application.
Then, it will prompt you to download the latest software for the iKON (2.0.026) and then it will flash the iKON with that latest software
Once the iKON is flashed, close the setup application, disconnect the USB and power off the iKON.
Now, mount it on the heli. I would not attach the servos to it yet.
Power on the iKON, attach the USB cable and open the setup application.
There are step-by-step instructions that you follow one screen at a time.
Follow those exactly and you will be in good shape.
