Default RE: Comp ARF Valiant

Canopy is now finished. Epoxy/micoballoons around the 2 blind nuts and alignment pins added. I went back and forth between using pins or the flat "hooks" provided into slots. I choose the pins as that seemed to work just fine on my Oxai Pinnacle. I used the same method as for the rear alignment pins. 1/8" CF rod into a teflon sleeve in a piece of balsa. Pictures should help. I placed 2 pins on each side, installing them 1 at a time with 5 minute epoxy and holding them in alignment untill the glue hardened. One problem was how to hold the balsa block with the teflon sleeve in place while the glue dried. I wanted to have it dry while the canopy was mounted and held in the proper alignment. For the front pins I tack glued a piece of balsa to the side of the fuse to act as a shelf for the alignment block. It was glued in place so the balsa block was held to a slip fit to the fuse rim. For the rear 2 pins I was worried that the fuse sides were too thin to have something glued to it and removed so I made the second support that was tack glued to the under edge of the fuse rim. I prefered ths second method. One issue in using the pins is that since the canopy is installed at an angle with the front up the pins do not want to go straight into the alignment blocks. In ordre to make this work the front of the teflon tube had to be relieved, and an angle sanded on the tip of the carbon fiber pins. Worked out OK, but next time I will probably go with the tabs and slots.

Fuse at this point with canopy and chin cowl mounted, rudder tray, rear canopy former extension and firewall mounted weighs in at 1048 gms.
