Teus says that his model, with the CG at 10.5cm, adopts a slightly nose down attitude. He further reports that in flight it resists turning with only ailerons and that rudder is required to make a turn. He also said that because his model has a lot of scale weight it flies fast. I believe my model weighs around 3.5kg.

Anyway, I think I'm done. (With the exception of making sure the engine runs properly.)
