It's not as simple as betaflight, but it's all there too be assisted, just no graphical interface.
Once you get it nailed down it flies really nice, too.
The MOSFETs are a bit of a rough project to learn soldering on, but it's not as bad as it looks.
Part of it though is that if you're replacing them it's because your FC is dead, so worst case it stays dead. That lowers the pressure a bit.
If you want I can send you a dead-dead FC to practice on. I put the battery connector on backwards and cooked it, so it's useless at this point.
