I found this video while surfing around on youtube and thought it was brilliant. I am amazed that it actually flew and if they even put any effort into trying to make it fly. To me it looks to be about the same size as the Parkzone Archer and is a bank-and-yank. Also looks like he used parts from the T-28. Thought I would share it to you guys, and mind the volume, they get excited and loud.
