As one of the CDs, I'd love to help you, and address any questions. However, I am unclear regarding your question. Can you elaborate on what you mean by "convert . . . to tail dragger retracts?" Are you saying only the mains will retract, and the nose gear will remain fixed? Or, that you want to modify a tri-gear plane to a full-fledged tail dragger configuration? Or am I way off the mark, and you mean something else, entirely?
