OK so I've got my 500efl running a mini vbar running express SW. Align ESC and motor ungoverned, MKS servos and standard blades.
I've noticed three things today and wondered if any of them are likely to be solved with a trim flight.
First thing is if I punch the collective up hard the tail kicks out a small amount but is brought back. I'm guessing the only way to fix this is pre-comp using Vbar Pro.
The second is if I go hard +ve, -ve, +ve etc to make the heli climb then fall rapidly then the heli drifts left a bit through it. During a piro I think it drifts right but I haven't tried a piro the other way.
The third thing is that sometimes during forward flight the heli kind of nods a bit, it's tiny but noticeable when it does it, but most of the time it doesn't do it.
It flies beautifully really, and these are picky things. This being my first venture into vbar or FBL I'm not sure what to expect a lot of the time.
