Concerning pattern flying with UCD 46: offers a challenge with the large control surfaces and high throws. Easy to overcontrol, even with low rates. Needs tight hinges, tight linkages, and a decent servo, especially on the elevator. I was chasing my UCD all over the sky with S3004's on elevator. As an experiment, switched to S9001 coreless. Seems to give better centering, less chasing. Maybe someone has a suggestion for low-cost servo that centers well without hysteresis.
