I have two questions regarding the taxi procedure runway. 1) When doing the flight control check I notice that the ailerons react to my movements but immediately return to their neutral position even though I have the yoke fully turned. In flight however the rudders stay in the position of the yoke.2) Do 747s taxi at idle thrust? It is quite annoying having to adjust the power up and down to keep a constant taxi speed.Thanks,Ron

1) As long as your hydraulics are "powered" the aileron should not nove to center position unless you center the Yoke. You say "the rudders stay in the position of the yoke", how are you controlling the rudders via the yoke? Not having any rudder pedals myself I use the ministick on my CH ProThottle as rudder, however only use the yoke for Elevator and Aileron (throttle, flaps and elevator trim).2) That depends on the weight of the plane. You should be able to place your throttle in a position that gives your more or less constant taxi speed (only small corrections will be required). You have to remember these engines has a long spool-up/down time so don't make too big adjustments and let the engine settle on the new setting.[link:fs2crew.com]http://fs2crew.com/betateam.jpgPelle F.

Hello-Can't really comment on the aileron issue- never really looked for a problem there, but I will pay more attention and comment. The only "sticking" of non-neutral control surfaces I experience is with the rudders and ailerons. Loading situations leaves the rudder (upper or lower) displaced, or a single outboard up or down. As soon as power and hydraulics are established, they center and work correctly.Re. The taxi issue- it is well known. The FS9 program has issues where PMDG could not model that and the flight physics correctly. They chose flight physics- and rightfully so. So, if you advance to about 36-37% N1 and once rolling retard to about 34-35% N1 you should be fine. She's a great big girl so give her time to get moving- watch your ND ground speed. I don't generally use differential thrust, but will occasionally advance the throttles slightly on a sharp turn. Spot on about lead times because of spool up- but nothing like the old JT9Ds (707).Obviously the above N1 settings change with gross tonnage.Best- Carl F.

Thanks to both of you! Always great to have a forum like this.The ailerons now work fine, think it had to do with the hydraulics not powered correctly.Ron
