The DG4 has a steerable nosegear so I can make tight turns on the ground and enjoy taxiing around WideAwake Island but the XR-1 and XR-2 have wayyyyyyyy to large of a turn radius (no steerable nosewheel) and they are useless to taxi with so I was wondering if there was a mod for the XR's to make them more realistic on the ground? Not sure about XR-5 because I have not tried it yet (it says it does have a steerable nosewheel).
