DX6i Transmitter Flap Mix

...tail-heavy no more

I took the Phoenix out for a fly this afternoon, not having flown it for a while, and took the opportunity to try the flap mix which was something I'd overlooked when I first got the transmitter.

I'd set the Phoenix up for flaps when I'd first got it, but have never particularly liked flying with flaps as it makes the Phoenix fly tail-heavy, dampening what are generally immaculate flying manners.

This is because the wings are in a high-lift configuration but the tail is not, causing it to dip at low speeds associated with flaps. The other day, flipping through the menu's when setting up the Stinger, I came across the flap mix menu and suddenly it made sense.

The mix is very simple, allowing you to dial in a dose of elevator with the flaps. Now the trick is, to cure tail-heaviness as in the case of the Phoenix, you don't want positive elevator, as this would just push the tail down more and increase the angle of incidence of the wings.

What resolves the issue remarkable well is negative elevator, effectively working as a flap for the tail. On the Phoenix I set negative elevator at 20 for a flap setting of 10, which I tried out this afternoon and which works brilliantly well.

Highly recommended on the Phoenix...
