I have a positive I.D. on your mystery aircraft. It is NOT a Top flight Elder, very similar but not an Elder. This is a model sold by Horizon Hobby, shown in thier"spring/summer 2004" "Air Time" catalog on page 17. They called it a "SuperFlying Models Eindecker .46 ARF". It is pictured on the same page as four other "Hanger 9" brand war birds however this is not a Hanger 9 product but rather a lower priced line of ARF's that they sold at that time (priced at $109.99 in this book). Recommended engines are .35-.46 2 stroke or .40-.60 4 stroke. They say it has a fiberglass cowl (Elder will have a built up balsa cowl), a wingspan of 63" (Elder is 65"), and it looks like it may have either fiberglass or plastic wing tips ( Elder will be built up balsa). Elder is a balsa built up KIT only, and this is a ARF. They list it as a "skill level 2" requiring previous flight experience. If you have never flown anything before you can not fly this model without help. With an instructor and a buddy box you may be able to learn on this airplane but not by yourself! Get help and this should be a nice fun flyer. Go it alone and you will turn it into a pile of sticks in......oh... i'd say.... 10 to 15 seconds. Good luck and good landings.
