The UCD has bad coupling from rudder into elevator and aileron, as we all know.
Has anyone yet tried to reduce the height of the rudder? This could easily be done by coming down to the first cross member and cutting the top off. The plane has way too much rudder anyway. I really believe this would be beneficial, and am toying with the idea of doing it.
Has anybody else tried this idea yet?
NOSRAM,
I decided to do what you suggest about the rudder coupling issue. Although I haven't flown it yet I believe it will be a helpful fix. I plan to fly it tomorrow (weather permitting). This time I took pictures of what I did throughout the process and will post them sequentially over the next 6 posts including this one. The whole process was quite easy and took less than an hour to complete. Overall, after cutting off the top of the rudder and then adding a new cap for strength and to get the new desired height the rudder height was reduced by 2.25 inches.
This first picture shows how I simply cut away one side of the monokote down to the first cross member of the rudder. This gives visible access to everything that needs to be cut.
