I had ride in light winds today with the P4 15m in light winds. I should have taken my SA2 but wanted to fly this one.

Anyway, I notice it backstalls easy in light winds (but not at all when wind picks up).

The setting is factory default but not even check what is it.

Is there any setting can change to help that, and what would be the effects on other flying characteristics.

thanks P4 riders.

John, Brian, ???

yes sir

All my P3 and P4 settings are

C: -3cm
B: -1.5cm

And when I measure all four lines at the end (holding them together) when it's fully powered, center lines are 1cm longer, meaning center lines are probably shorter than control lines.

When I flew P4 10M stock and felt a ton of backstall. When I measured all four lines, center lines were 10cm longer than control lines.

thanks Brian

I'll check this
