I was 15 when my father was designing and producing these kits as he was one of the R’s in TRI-R. I remember watching the maiden of the prototype as I did with all the kits and it was a great flyer. I have the YAT I finished in 07 and it flies great. It will be extremely hard to find anything on these kits. Back then adding pictures to the manual was not in the cards as these were produced in a basement with jigs and band saws, circular saws and a host of creative production methods. I hope you enjoy the build. I traced all the parts before I built if I decided to do it again or forward to a kit cutter.
