Please do not modify the original .acf.  Any modifications will appreciably change the flight characteristics, and at the RC scale very small changes can have large effects.

Example specific to the Raptor 30, the CG is -.04 default position.  If you make it -.03 or -.05 flight characteristics change dramatically and stationary hover is degraded and pitch up in forward flight characteristics change.

If you wish to modify the .acf to match an RC helicopter you have, please do a SAVE AS and rename the file to match your own helicopter. This way your changes will not be saved to the original and when/if the modifications result in an unflyable model, you can revert to the known good .acf.

For non-commercial, private use only.  For RC orientation and operation training.

This model is not licensed by ThunderTiger. This model represents the Raptor 30.
