Hi guys, I have noticed even with half tanks of fuel, just getting the 9s to move takes almost a quarter from full throttle. Does it really take that much thrust to get them moving in real life? Never been on a 9 so I have no idea.
Thanks
Bill

YES .... we know about this ! Taxi does .... unfortunately .... require excessive thrust !!!! It came up in testing. There is a ground fruiction problem there, but, as yet we've not been able to resolve that particular issue. If we get the the ground friction/taxi thrust right .... then we end up with an aircraft that's far too agile in flight, so, for the moment at least, it's one extreme or the other !  Mark C BOG/CO |

Ground friction is a general problem
I've been told that's why piston aircraft have to have a lot of throttle added to move....like turboprops...... when in real life they taxy off on near ground idle.
Difficult one to balance.

Hopefully there will be a solution to this, but in the mean time your DC-9 series are amazing

I'm afraid not Bill/amigo .... at least not at the moment or in the foreseable future That friction issue, as I've encountered it, seems to be more applicable to some aircraft than it is in respect of others .... and is a natural FS bug. If we get the thrust/ground roll right .... then we also suddenly end up with an aircraft that's too "eager/excited" when it gets airborne. You will require a little more thrust that is realistic to start taxiing the DC9's, but, I've found, on the basis of my "many hundreds of test flights", that once rolling at a good/sensible taxiing speed .... then it doesn't require too much more thrust than is realistic maintain the roll. "IF" you're having to apply rediculously high thrust setting to maintain a sensible taxiing speed .... then that may be suggestive of another issue .... even, possibly, a scenery related one .... I hazard to guess   If you're too heavy/overweight .... then that won't help things either. In this case try reducing your aircrafts all-up weight and see if that helps improves things .... just a bit ! Mark C BOG/COL |
