I may be off base here with this and you've probably already taken care of it by now, but the Tiger Bipe & the old Ace 4-40 Bipe share an awful lot of similarities. You might consider getting a set of plans for it from RCM's plans service; it's number 977 and should have the dimensions for bending up and making a replacement set. I have the old RCM that it was published in and have an old 4-40 Bipe that I purchased second hand but no plans. However, reading through the construction article and looking at the two planes they seem remarkably similar in their design. It wouldn't surprise me in the least if Thunder Tiger took the 4-40 Bipe and changed a few details of it to make it their own (especially since they no longer offer the kit) and then offered it as an ARF. Just a thought; hope that it helps someone!
