Most likely a China Based Company, do you have a link? I just purchased a B25J 96" wingspan, twin 65's to mount its an ARF, was little bit hesitant about buying it because Ive never heard of the Brand, took a chance ordered it at about a 1/3 of the cost of say a Hanger-9 or other known Kit manufactures, i have to say its very well constructed the covering was wrinkled but a hot iron took those away, parts fit great and not much altering needed as far as squaring the plane up, id buy another one from them its a nice plane built real solid.
EDIT.. on the supertigre engines ive had one on my P51 and never have had any problems,
