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.

If you wish to modify the .acf to match an RC you have, please do a SAVE AS and rename the file to match your own aircraft. 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.
