Been out of the hobby for over 10 years... I started in later 80s, ah the days of mechanical gyros (which froze up in flight), Enya engines with supertiger carburetors, and radios with pot adjustments. No such thing as flybarless!
Anyways, I finished a 450L test flew last couple of days and so flybarless systems are new to me.
Programmed the 3gx and ESC as per the manual.
Issue is when I do a pirouette the heli tends to drift off a little backwards, however, it's not bad. If I just hover in one spot its quite stable. Flies around just fine. A friend who has 450L but with a Vbar, flew mine and did some 3d with it, he says it flies almost like his with the vbar and he did like the feel of my setup, but he also note the minor drift while pirouetting.
So being new to this, what can be adjusted to better stabilize while pirouetting? Balance, trim and subtrim is neutral. 3gx is square with frames and mounting plate.
