I've been playing a lot more with hover settings of late, and am making some progress. I've got the general flying feel about where I want it, and tend to run 25% (ish) expo on a bit of a hybrid - it's a T-Rex 700L v2 running the SAB F3C head (2 bladed) from the Urukay. I run around 1,380 r.p.m. in the hover, using the Align F3C blades (700mm).
I tend to use dual-rates to fine tune, but the rotation rate is really what should be used as I understand things, so I fine tune, then go back and adjust the Spirit settings so as to not have to have dual-rates in play. Flight style is 8, and I tend to turn down all the values based on the
Tuning Guide, but probably still have a way to go to things just right there - I imagine coming from a 'flying' tuned system to one simply for hovering is muddying the waters for me a little there.
The one thing I have found is that the helicopter does tend to drift around a lot more in the hover with no input compared to others (running Futaba or even vbar), but I do not know why. The helicopter is mechanically accurate - I use the
Soko tool to make sure all is completely accurate, and then fine tune e.g. pitch range in the Spirit to make sure of equal travel etc. I did wonder if vibration was an issue, but it's logging approx. 6% on the GT, so it's not likely that.
I'll share my settings once I'm back on the 'other' computer.
