| Before the fiberglass wing tips can be fitted to the wing structure, some modification is required that involves removing some material. |
 |
| I found this cutoff wheel for my dremel that I had used for something else decided to give it a try on the fiberglass. It worked very well as long as I didn't get in a hurry and applied minimal force. If not, the wheel had a tendency to "grab", which cause problems. |
 |
| The description in the plans for the required cuts on the wingtips was slightly confusing for me (not hard to do). I found it helpful to hold the tips in position so I could visualize what was taking place. |
 |
| When making the cuts, I made sure to always "leave the lines". Much easier to remove material than to put it back. |
 |
 |
| After a few trial and error fits, the wingtips fit nicely. The plans advise to use a strap to ensure the leading edge of the tips fit snuggly in the leading edge of the wing assembly. |
 |
| Holes are match drilled from the wing assembly into the fiberglass tips for later installation of nutplates. We found while drilling, some areas of the fiberglass tips tended to push in with the slight pressure of the drill bit. We used a suction cup for a GoPro camera to help hold the wingtip skin in place during drilling. |
 |
| Clecos are added as drilling progresses from fore to aft. |
 |
| As common to most all wingtips it seems, we ended up with the tip slightly longer than the aileron trailing edge. This will require some trimming and fiberglass work. |
 |
| I drew this red line as a possible option to cut to make the trailing edge of the wingtip match the aileron. You can see it is not a straight line but trails aft to meet the existing outer edge of the wing tip. I haven't decided if this would look ok, and/or not cause any adverse aerodynamic affects, or I should just trim the edge straight. I'll have to do some research and decide later. |
