ID:	2003 Well guys looks like most of us are locked up for a while. So there is no better time than build a new airplane. The build I will be doing is a Extra 260 from Silhavy AeroSports. This is an excellent kit with all the ply parts fitting snug and accurate. For those that have never built from plans and a box of parts you should find this very interesting how a aerobatic plane is constructed.
    Thanks to Toby Silhavy and Ben Batts for the design and modifications and the precise laser cutting of the ply and foam parts. Enjoy

              Cool! So CA on motor box, not epoxy all around? Where did you get T-88 and what is it’s cure time? I use the Bob Smith epoxies but they tend to cure too fast for large quantities.

                  David using CA to glue the motor box is just to make sure all the joints are tight and straight. Not to mention not having very sloppy glue joints that you would have to go back and clean up.
                  Once I am done with all he joints you will see in the next step that all joints will be reinforced with triangle stock and T-88.

                  Google T-88 it is available online several places. I have used it for years it is ideal for building because is slow.
                  T-88 is a high-performance, non-brittle, two-part epoxy adhesive designed to give superior results under adverse conditions. The adhesive may be used without modifications in normally fitted joints, and will cure without shrinkage.

                  T-88 is clear amber and becomes virtually invisible when varnished. T-88 exhibits outstanding adhesion and permanence on a wide variety of materials, and is endorsed by leading designers, builders and organizations.

                  Full Cure @ 77°F (25°C) 72 Hours

                    Just found the build Mike, I just put together a Aero Works Extra 260 in a 50cc size. I'm going to watch this build very closely. I may be interested in this kit. Keep it coming!
