Different wings on OV-10A?

mdatelmi · August 19, 2010

Flying with the OV-10A in WoV I noticed a strange flight attitude...well, for me...maybe it's normal in the "real" plane...

During a high bank turn...at any speed and any direction...and during a pull-up the plane always do a roll in the right direction.

I'm not a modder or a flight model expert but checking the data.ini I noticed this:

-------------------

The wings value aren't equal...I checked in other planes and here the wings seems equal.

My questions:

- It's the OV-10 data.ini ok or is corrupted/wrong?

- if wrong which wing values are the right ones?

Thanks in advance for yours suggestions!

Yes, values on one side should mirror those on the other, and, that FM is not SF2 friendly. Try mirroring the first set, keeping in mind that the stall values are somewhat optimistic, and that the Ymac for a left side surface is always expressed as a negative value, while that for the right surface is always a positive value (think of X,Y,Z coords, and you'll understand).
