RE: Heng Long Protocol
Simon, you sound like you know what you're doing and I will be looking forward to your conclusions. [sm=thumbs_up.gif] Whether you come up with easy, do-it-yourself improvements that can be made to the existing electronics or whether you design a whole new board, I'll want to know.
Several of the guys on this forum keep "spare boards" around and/or use fans to keep their electronics cooler, so the HL design can certainly be improved upon. Thanks for putting time and effort into the problems! [8D]
