Taxiing Alphasim's SR71

[HarvesteR]

Hi,

i don't know if it's just me, but i'm having real difficulty in taxiing alphasim's SR71...

the bird just won't turn... it makes it incredibly difficult to follow a taxyway (even wide ones) and lining up to a runway...

i tried editing the aircraft.cfg, but couldn't find a proper entry to increase the nose wheel travel range

any help is appreciated  :)

Cheers
