Hi  :)

About the POWER ISSUE from the 200:

You can change some things in the aircraft .cfg your
one if you wish to have more power.
Look for those entries in the aircraft .cfg :

[TurbineEngineData]
fuel_flow_gain = 0.002                        
inlet_area = 19.6                            
change this to 13.6 so it  reads:
inlet_area = 13.6

and:

[jet_engine]
thrust_scalar = 1.0
change this to  (1.1 or 1.2 test it your own i use 1.1 ) so it  reads:

thrust_scalar = 1.1

that should do the trick   :D

Backup your orginal Data before change so you not losing sometthing.

cheers
