I have one, I couldn’t work out how to do it on mine, so I just did regular twin on my mini guinea. I am not sure it has the required number of mixes. Regular twin engine flies fine on it, flat spins are out obviously but ypu can do any of the FT twins without differential thrust.
It’s pretty much the same menu architecture as the Flysky FS6I, maybe the method for that would be adaptable? Hopefully some smart person has an answer, as I would certainly change my mini guinea to see how much difference it makes.
