Challenger II doors
picture project

Let's figure out why these planes have yaw problems with the doors on

If your plane has yaw problems with the doors on but flies fine door off, please send the following information to:

1. true w/b, not just CG but weight on mains and tail

2. get pictures of the doors (mounted) on the plane

3. get pictures shooting down both sides of the plane (doors on/off) in the direction of airflow to the fin/stabs and from back to front, too

4. get pictures from front, back and each side.
