I installed it on the Green Cube Solo about 3 weeks ago. Haven't done a whole bunch of flying in South Florida due to the weather (it's the rainy season now). Hopefully I can get some flights in this weekend. I actually like the way it flies. Without changing any parameters, it glides to a stop. I updated the braking parameters as suggested by Matt in the Facebook thread, and it now feels more like it did with Open Solo 3.0.0. One thing i noticed is that the parameter for vertical acceleration had a low value, something like 133, when the max is 500 (cm/s). It had very slow vertical acceleration. I checked it against the Open Solo parameter on my stock quad, and that value is 400, so I changed the Green Cube Solo to 400. Much better now. One thing I cannot do is enable RTL. Anyone had any success with this? I don't see it as a flight mode that can be enabled in Solex.
