thank you for your deeply considered replies HB, PC and. sevo i am sure after the 15 minutes of hard thought, that you gave my musings you had no problems coming to these respectful conclusions. I had hoped that whoever had made the RC Command BUs had considered continuing. Or that Bob from RC Command had possibly sold or traded the design, or someone may be considering a continuance without being a RC Command product. but your responses were so much more appropriate and in the future I will be sure to elicit your considered opinion or make a equivalent response to your thoughts or questions.
