Florian Kuehni when you go to build the Ryan throw away the hinge set up that is in the kit. Instead use Dubro hinges they will help out the control surfaces a bunch. I just replaced the hinges on mine and they are working just fine. If you don't you will have a lot of play in the hinge line later. Of corse I converted my extra ST Ryan to a bipe and she looks quite good. I still have the original ST Ryan also but the bipe realy looks quite well. Of course I don't have the wheel pants anymore but I found a set and I think I mite try to use them on the bipe. If I could ever figure out how to post pictures on the web site I would post them for you to see. She is also covered in chrom monokote with a checker board pattern on the bottom of the wings. If you have any questions I'll be glad to try to help.
