Model weight
Weight of your model in kg.Aileron moment of inertial
Elevator moment of inertial
Yaw moment of inertial
The moments of inertia define the model tendency to oppose the rotation speed along the axis mentioned. The moments are rather large, if a lot of mass is mounted far away from the center of the axis through the CG.Front view detrimental drag area
Side view detrimental drag area
Top view detrimental drag area
This value defines the way, the visible front (side or top) area influences the drag an area produces at increasing speed. If the speed is increased, the resistance arising from the drag reaches a value that will not allow any further speed increase. This is the model top speed value. Increasing speed not will call for a lot of additional engine power. Reducing the drag area allows higher speeds..
Damage at load multiple of
If accelerations above the described value work on your models, some structural damage will apply and the model crashes. This usually happens during hard landings or dives from high altitude and strong elevator commands at high speed. In this case, the blade holders of a real model may break apart..Side fin area
Elevator fin area
These areas stabilize the longitudinal axis in the direction of flight. Higher values increase stability.
Center of gravity below rotor head
Positive value produce a CG under the rotor head, negative values show CG's over the rotor head.Distance of CG in front of rotor head
Positive values: in front of rotor head
negative values: behind the rotor head
