Ventus 3 Flaps

Post by ni2803 » Wed May 20, 2020 9:43 pm

Hey i found something that is not correct with the Flaps of the Ventus. Its the Flap postion. When you set the flaps to 0 there are not 0 there are more like +1 only when the Flap position is -1 then their are neutral

That is correct. Flaps -1 is flush with the trailing edge cutouts. It is the normal cruise flight setting. Flaps 0 is a slightly more positive setting that has less drag at low speed. But for normal straight flight flaps -1 is optimum and is the setting for which the profile is most optimised.

Checked today on a real Ventus 3M. At the root 0 is slightly positive and -1 is slightly negative. At the tip both are positive relative to the fixed part of the wing.
