Place those Options inside your GameUserSettings.ini under the section "[DModify]"

If no Option was set, this is the default for all ridable flyers:
SpeedStep=0.025
MaxSpeed=300
BaseSpeed=<HardCodedValue> or if unknown: 100

Syntax:
You don't need to define every single suboption. If you don't want to use e.g. RotationMulti, then just don't define it.

BaseSpeed:
(If your target dino isn't a ridable flyer this Option is ignored)
The value is normally hardcoded into the mod, but if you want to override it, because it's missing or not correct, then you can use this option. It sets the default BaseSpeed of the dino before modification. (e.g. Argent => 100, Tapejara => 136.5).
Tihis value is used for calculation (together with SpeedStep) and also as the value which is taken if you unequip the costume.

SpeedStep:
(If your target dino isn't a ridable flyer this Option is ignored)
Defines how much speed should be added every LevelUp.
It represents the percentage of the dinos base speed.
Example:
Base speed of your dino is 100% and your SpeedStep is 0.02, then your dino will get a +2 speed on every LevelUp (100 x 0.02 = 2).

MaxSpeed:
(If your target dino isn't a ridable flyer this Option is ignored)
Defines the max speed your dino should be able to reach.
When this value is reached, then the Implant stops increasing speed on LevelUp and stays at this value.

StaminaMulti:
Increases or decreases all stamina consumtion values I found at once.
Values above 1.0 increase stamina consumtion.
Values below 1.0 decrease stamina consumtion.

RotationMulti:
Increases or decreases the turning radius of your dino.
Values above 1.0 make turning better.
Values below 1.0 make turning worse.

ForceRideFlyer:
By default this option is set to False.
If enabled (True), then the implant will treat the dino as a rideable flyer, which, by default, isn't able to level up speed. So please don't use this option on dinos which can level up speed the default way!
