Yes, we have a white Labrador! It's not possible to vacuum the fur in my office. I've decided to consider it as insulation!
Question... in case anyone is even looking at this thread and can help. Notice the rudder above. For a flying wing with the rudders way out on the tip like this... it's best to have them work only one way. I learned this studying my plans for Burt Rutan's Long Eze. They only move outward. This is very easy to accomplish with one servo by just using a string. When I want to yaw to the left, only the left string is pulled and moves the rudder above outward... causing more drag on the left side (pulling the wing backward) and to a far lesser degree the force to the right. The right rudder will still be pointed strait back not creating any drag.
The question is... do you think I need a spring to return the rudder to strait back? The string isn't going to push it back. My current assumption is... without the tension on the string to pull the rudder out, the airflow will push it strait.
