I've adjusted fuel scalar and engine inlet very successfully on some a/c so that now I get almost book values for both. But the rate of FF is not exactly right. Do I adjust fuel flow gain for this? If so, are there are any rules for this item or is it just trial and error?Also, the pitch of some of my add-on a/c is excessively high with certain flap settings and I want to reduce the body angle. How do I do this?Appreciate any posts and advice, thanks!JS

To get your fuel flow as you want it, look for this line in your aircraft.cfg (I lifted the one from my MD-11 for this example)GeneralEngineData//0=Piston, 1=Jet, 2=None, 3=Helo-Turbine, 4=Rocket, 5=Turbopropengine_type = 1fuel_flow_scalar = .77 <-----change this valueengine.0 = 11.25, -27, -8.9,engine.1 = -92, 0, 13.8,engine.2 = 11.25, 27, -8.9,A higher scalar raises FF, a lower scaler lowers FF. Simple enough. As far as rules go, you could look up the cruise specific fuel consumption of the engine the aircraft is based on. If it is for example .500, then you would set the scale to 1.00 (the scalar value/2 = SFC). But sometimes, real world values don't give real world performance in Flight Simulator. So you'll have to experiment if this is the case (good ol' trial and error).Now to get the nose down when you've deployed the flaps, head down to the flaps sections of the aircraft.cfgOnce again I have lifted the section from my MD-11Flaps.0lift_scalar = 1.0drag_scalar = 1.0pitch_scalar= 1.0 <---change this valuetype=1span-outboard=0.500000extending-time=45system_type=1flaps-position.0=0.000000,0.000000flaps-position.1=0.100000,0.000000flaps-position.2=5,0.000000flaps-position.3=15,0.000000flaps-position.4=25,0.0flaps-position.5=28,0.000000flaps-position.6=35,0.000000flaps-position.7=50,0.000000Try increasing, and then decreasing the pitch scalar, and see which way moves the nose in the direction you desire. For BOTH of these problems, a more proper fix would be to go into the .air file and work with a legion of values, but these scalars will provide a simple, easy to test fix.

Thanks, Albaro, I appreciate your post and shall try as you suggest.Cheers!JS
