Hi Joachim, Yes, the AN-225 does incorporate steering on some of the main units - according to http://www.air-and-space.com/Antonov%20An-225%20Mriya.htm it's the rear four sets. This site also has some nice pics of the main gear, which show that the front three and rear four units are different, if anyone would like to make more detailed and accurate main gear units:) The AN-225 also has a max taxiing weight but I couldn't find the doc which stated what it was:( Basically, it means that the AN-225 cannot make ground turns above this weight and so for mtow takeoffs it has to be lined up on the runway and then loaded. Unlike the AN-124, from which it was developed, it was never intended for short-field operation. One new 'fact' I found while trying to find the max taxi weight was that the takeofff run at mtow is 3500m (11500ft). I think the FG AN-225, at mtow, gets off the ground a little shorter than this - iirc, I tried to tune it so that it could just, and only just, get over the hills after leaving on KSFO 27, figuring that it would be in the right ball park and that it had to work at the default FG airport.
