VTOL/Hover (V4.0) for Wilco Tiltrotor
This freeware package adds new V(S)TOL & Hover features to the Wilco BA609 Tiltrotor. This solution is based on overriding the normal FS flightdynamics when the nacelles are rotated out of the normal flight position; in short, it's a V(S)TOL & Hover FDE coded in a gauge.
To use this addon, you need to have the (payware) Wilco Tiltrotor installed, and working, in FSX. The README includes extensive installation and flying instructions.
