SM, that is an amazing job. A hearty "WELL DONE". It's folks like you that are helping to save the very heart and soul of the building side of the hobby.

One aspect that will affect your flying is the generally farther ahead balance point used for control line flying. That means your higher than normal CG is just that much closer to the landing gear so it makes it just that much more likely to have more noseovers. One way to get around that is ensure you land with a touch more flying speed than normal and use the extra control authourity it provides to lever the tail down. Once you tip it nose up it'll stand a far better chance of it staying that way.

If you're building a mule to learn all this one try playing with the technique on that one first.
