The Carl Goldberg Yak 54 EP was a balsa/ply, park flyer-sized, fully aerobatic electric radio controlled airplane originally designed by Carl Goldberg Products, Ltd. of Oakville, Georgia USA. Intended for release in the latter part of 2006, the Yak 54 EP was in production in China during negotiations for the sale of the company to Champaign, Illinois-based hobby distributor Hobbico, finalized in August 2007. As a result of the negotiations, the model did not appear in the final independent Goldberg catalog nor did it appear in Hobbico's dealer newsletter, Great News.
