I just built assembled one of these ARF's a few weeks ago. One little tip with CA hinges that SIG didnt mention in the instructions was to drill a 1/16 " hole in the middle of the hinge slots. This helps the CA wick its way down. If you dont know what I am talking about, go the
www.greatplanes.com and download any of the instruction manuals for any af their ARF's and check out their hinging instructions.
The K & B 40 will fly this plane but it really deserves a good .46, .50 or the Irvine .53. Or if you have the extra cash, pickup a Y.S. 63 and it will be an animal!
