hello all.. lately ive been flying and fiddling around with the Isdt ATR 72-212 merged with the F1 Atr panel
These are my engine and propeller stats right now..they currently provide great engine performance for me..I can cruise at 23000 feet at about 210-220 knots. with throttle in the green at about 60-70% and cruise mode selected:
[GeneralEngineData]
engine_type =5
Engine.0 =5.400, -10.150, -2.000
Engine.1 =5.400, 10.150, -2.000

rated_n2_rpm, static thrust, and thrust scalar...have all been modified to accommodate a FS2004 tweak that provides a realistic feathering effect only available on ISDT ATR aircraft..(
)..but it doesnt work well in FSX using the same modified parameters(propellers spin too slowly in FSX)....After much fiddling around I've discovered that for the feathering tweak to work in FSX.. rated_n2_thrust has to be increased to about 70816...unrealistic value that leaves the engines almost powerless..but it gives a very cool realistic feathering effect.
My question is...if at current values(rated_n2=40816, static thrust=105, thrust_scalar=0.875, and fuel_flow_scalar=0.2) the ATR responds and flies like a charm(imo)..If i place Rated_n2=70816...what else would i have to modify..and to how much...so that the ATR responds as good or near as good as it responds now?? Should I use a simple math equivalence..between lets say static thrust and rated_n2 ??(example, if 105=40816, then X=70816 ??(lol i wish it was that simple but any help would be much appreciated))
I plan on releasing my ISDT ATR 212 aircraft.cfg and soundpack both modified especially for those who use this aircraft with the Flight1 ATr panel merge..but i would like to hae realisitc feathering modified into that aircraft.cfg as well..
