Carbon tow spars fabricated


Card stock paper glued on top of spar formers with CA to seal the gap between them


Card stock gap seal view from bottom show channel between spar formers to lay in carbon tow


Area taped off to keep epoxy off surfaces


Stab carbon spar tubes scratched and scuffed with Perma Grit file to get good bond of carbon tow


Popsicle stick stuffing tool made to stuff carbon tow down into spar channel


19 long strips of carbon tow wetted out on wax paper and stuffed into each channel of front and rear stab spars. The scientific number of 19 was because that's how many I got laid out on the first strip of wax paper, so I just did it again for the other spar!


Next 4 short strips were wetted out for each spar. Turns out it was a good guess since it filled the channel up in the center


Paper towel squares stuffed in the channels to absorb excess epoxy


Finished layup of both spars


Peel ply strip placed over the spar layups and tape added to keep it flat


Layup cured and tape removed


View from top after cure


Foam plugs replaced in front and aft of stab


Foam filler applied and sanded and new Promodler HV elevator servos dry fit
