    That could easily work, BUT: I am not familiar with CFS, but downloading one of the planes I see an aircraft configuration (cfg file), with an entry for

    [flight_tuning]
    cruise_lift_scalar = 1.0
    parasite_drag_scalar = 1.0


    These control the scale factor for the total drag as discussed. Fiddle with the parasite drag scalar only, see how it works

    This might provide some idea of what I am talking about:

    Ted,
    That's exactly how I would do it in CFS2, CFS3 almost the same. Something like a 1.2 to 1.5 on parasitic drag will take off about 5-10 kph or so.

    The cruise lift scalar is not about drag but the pitch of the ac when at cruise/max speed, which also combines with CoG.

    Don't be tempted into using - or negative amounts with drag, to gain speed, as this can haves odd and bad effects!

    Cheers

    Thanks for the starting figures, will make it easier to get the speed I am looking for.

    tsk

    Looking good Ted, btw I know I've been quiet, but I have made progress on the Whitley pit

    No worries, John genius takes time! Just about finished with mapping the exterior of the C6 - the oil cooler cowling is a bit messy, but no one is perfect.. The Rs will be easy enough just new engine cowl mapping and a few other parts. The vc, have I ever told you how much I hate mapping the vc......

    Mapping away the C6

    Had a couple of hours this past week to map the planes. Not perfect but when John gets done you'll never know...

    Mike,

    Hmm, I could model a C6 or R1/2 (0r any plane for that matter) with top speeds without the aerials. Then go back a fiddle with the parasite drag figure to reduce speed to the limit I want....hmmm sounds straight forward enough.

    tsk
