I just bought a used FS one unit with the Tacon radio and after downloading the upgrades to 1.0.9 the prop on the plane just barely turns at full throttle until I use the shift key on the keyboard. As long as I hold down the key I can fly the the plane. All other controls work perfectly. Any help would be appreciated.
