Looking for a cool lockdown/winter project? Do this!
This is assembling an open source based FBL controller and installing it into an OMP M2.
Why do it? Well, you end up with a fully configurable and innovative flight controller with top notch flight performance and some very useful telemetry features.
Like what? Like motor current telemetry, so you can monitor the actual battery power used. Also, you have access to all of the FC parameters so you can configure it directly from the transmitter.
If I can do this, anyone can. I got into r/c helis nine months ago during the first lockdown, starting with a Nano S2 and a DX6. I then moved on to an OMP M2, and when I started on this project I knew nothing about FBLs, ESCs, OpenTx, etc.
Was it a lot to learn? Yes, but if you have the time to read, why not?
What I have tried to do here is highlight the internet sources which I found to be very useful and add a few tips based on my experience.
The thread that started it all, by eqtrian, introduces the project and documents its progress (page 1 and the bottom of page 18 are perhaps the most important):

His package contains the following files:
- compiled firmware for the FC board (Heliflight 4.1)
- a dump of the commands for configuring the
