Savage Cub Rotax 912 ULS/S fix v0.5
This add-on changes default Savage Cub Rotax 912S to be closer to POH and BRP specifications for Rotax 912 ULS/S
I wanted to go for numbers to be similar with what engine docs and Zlin Aviation POH’s give + youtube, I don’t have any real-life reference, please be aware and feel free to comment.
Version 0.5:
Maximum static RPM = 5500 ;for me it was never get higher then ~4800 at ISA in default aircraft at run up and even in the air.
Climb rate = ~1000ft/min ;POH specially indicate it as a feature for aircraft so it is one of the references
Performance, RPM, GPH, Speeds & Power settings now more correct at ISA and realtime weather settings ;as reference too, sometimes throttle is 5% higher then POH stated
Changed:
max_rpm_mechanical_efficiency_scalar = 0.58 ;default is 0.43
thrust_scalar = 0.87 ;default is 1.25
DisableParkingBrakeControls = 1 -> DisableParkingBrakeControls = 0 ;just for convenience
Issues:
Oil Pressure at maximum RPM is in low yellow arc
Throttle position for some power&speed settings is 5%higher then settings stated in the POH
(Not an issue) for now it is ~ 2 GPH at 4000RPM. I don’t actually have found what real GPH for Savage Cub is, so help would be appreciated.

It is an ongoing small simple project and i will be glad to hear your opinion and experience, especially from pilots who had experience with this Bush Beauty. Feel free to test this add-on thoroughly
Next steps for me is to implement numbers for engine systems and dimensions, such as piston volume, pressures, temps, etc, but for now it causes engine to be unstable so that is why i go for now with mentioned parameters to be modified.
