Worked some more on the tune. I am now 100% against the statement quads fly fine on stock pids in Beta Flight. I will leave it at "Quads fly on stock pids".
When it comes to the Gremlin it is actually harder to get it to fly accurately then the larger quads. I am finding this out more and more now that I am getting used to a different lens then I normally fly with. To hit gates sized for the Gremlin and be controlled its is harder as you as constantly flying in ground effect. This requires a completely different approach then flying fast above 3 feet or doing freestyle with them.
The level of precision with throttle management is exponentially more important then any other quads I have flown. There is a seriously minuscule range where you go from low flight to tumbling. Its almost like the throttle calibration will not allow for such a precise low stick set up. Its like a 10-20 us range where you either pass under the gate or you tumble thru it with this tiny thing. I also think a lot has to do with the props requiring the torque to keep spinning at low rpm on motors that are made for higher rpm efficiency.
I do think it is able to be set reliably but it is surely tasking me to think different on how to do it. The next thing on my list is to try some reverse expo on the throttle to stiffen the stick control on the extreme low end.
Anyway here is the latest testing run with what I have worked out for my set up.
